If you or a loved one has been diagnosed with multiple sclerosis (MS), you may be unsure of where to turn. MS is a complex autoimmune condition, and no two people experience multiple sclerosis symptoms in exactly the same way.

Here, we'll explore exactly what a multiple sclerosis diagnosis means, the different types of MS and how they can show up in the brain and the body, and how to take steps to take control of your health following a tough diagnosis.

What is multiple sclerosis?

Multiple sclerosis affects several parts of the body, including the optic nerves, brain, and spinal cord. These components make up the body's central nervous system, which is responsible for receiving, processing, and responding to information perceived by the senses.

While researchers don't fully understand what causes MS, it's clear that the condition causes the body's immune system to attack the central nervous system. The nerve fibers that run through the body are coated in a protective layer called myelin. When a person develops MS, the myelin is damaged, which interferes with the messaging between the brain and other parts of the nervous system.

There are many different symptoms of MS, including:

• Numbness
• Mood changes
• Tingling
• Memory issues
• Pain
• Paralysis
• Fatigue
• Blindness

Some people find that they only experience multiple sclerosis symptoms during flare-ups, while others experience symptoms on a more consistent basis. Flare-ups can be caused by an infection in the body, not getting enough sleep, and inflammation in the body that may or may not be related to eating certain foods.

Understanding how your body is responding to MS is a key first step in managing your condition. In addition to knowing what causes your symptoms to worsen, it's also important to understand your classification of multiple sclerosis.

Types of MS

The type of MS you have may change over time. As you work with your healthcare provider to understand and manage your symptoms, they'll keep you updated on the current classification of your condition.

Here, we'll explore the three main types of multiple sclerosis--relapsing-remitting, primary-progressive, and secondary progressive, as well as clinically isolated syndrome.

Relapsing remitting MS (RRMS)

The most common type of multiple sclerosis, RRMS is characterized by periods of fewer or no symptoms, followed by periods of relapse. About 85% of people with MS are diagnosed with RRMS.

During the recovery period between each relapse, RRMS does not get worse. During each relapse, however, symptoms tend to increase in severity.

Relapses of MS are defined as the appearance of new symptoms or the resurgence of old symptoms. Keeping a journal of your symptoms can help you and your doctor to understand lifestyle factors or foods that may push your body to relapse. Typically, relapse symptoms begin and worsen within a matter of hours or days, and may remain active for just a few days or for several months.

While some relapses require inpatient treatment, often, symptoms can be managed at home. Some people find that symptoms come and go during an RRMS relapse. The return to the recovery period is often gradual, with relapse symptoms fading over time.

Primary progressive MS (PPMS)

Most commonly diagnosed in people aged 40-49, primary-progressive MS becomes worse over time. PPMS only accounts for about 15% of all MS cases. Many people don't notice that they're showing symptoms of MS at the start of the disease, as early indicators of PPMS are typically mild.

Unlike other types of MS, people with PPMS don't usually experience relapses. Their symptoms usually stay consistent for long periods of time, with a gradual increase as the disease begins to progress.

People are diagnosed with PPMS when their MS symptoms are apparent and get worse over the course of a year (rather than relapsing MS, in which symptoms get better and worse over time). In order to diagnose PPMS, your doctor will take an MRI of your brain and/or your spinal cord, looking for at least two lesions that formed at different times. You'll also have a lumbar puncture procedure. Your treatment team will analyze your spinal fluid, looking for antibodies that indicate the presence of MS.

There are many ways to manage the symptoms of PPMS, including lifestyle changes and medications. You may find that a combination of medication and lifestyle changes works to slow the progression of your symptoms.

Secondary-progressive MS (SPMS)

Sometimes, MS progresses into different stages as the severity and frequency of symptoms begins to increase. Relapse remitting MS (RRMS) can progress into SPMS for many people. During this stage of the disease, symptoms are continual, without a recovery period. In order to diagnose a progression to this stage of MS, healthcare professionals look for a six-month period during which symptoms have continually become worse.

While there's no cure for MS, some drug therapies can be helpful for people with SPMS, including beta interferons and siponimod. Your doctor will also work with you to develop lifestyle strategies to help you manage your symptoms.

Clinically isolated syndrome (CIS)

If your brain shows signs of damage that's similar to MS, and you've had symptoms in line with MS, it's possible that you may be diagnosed with clinically isolated syndrome, or CIS. Many people who are diagnosed with CIS are never diagnosed with MS.

Consistent physical exercise is foundational to any weight loss journey, regardless of your current health or the goals you’re pursuing.

When paired with a healthy diet, physical exercise can help people from all walks of life maintain a healthy weight while creating long-term, sustainable habits to improve their lives.

Creating a consistent exercise routine takes time and commitment, and giving yourself grace is essential as you find the forms of exercise that work for your body and your lifestyle.

Fortunately, there are so many ways to get physical exercise, and walking outside or on a treadmill is one of the most common ways people choose to work out.

This post explores the many benefits of walking for weight loss and why it’s such a popular form of exercise for people of all different ages, sizes, and backgrounds.

Key benefits of walking for weight loss

As you explore walking for weight loss and maintenance, there are important benefits you should know about.

While walking comes highly recommended by medical professionals, it’s also a popular choice for athletes, those recovering from injury, and everyone in between. Let’s explore why this form of physical activity is so widely embraced and what positives it can bring to your journey.

Metabolism boost & burning calories

Metabolism plays a role in weight loss; it’s defined as how your body uses energy or burns calories. Unfortunately, we don’t have total control over our metabolism, which is partially related to genetics and our health history.

However, some of your metabolism can be controlled by lifestyle and the activities you perform regularly. The more movement you participate in during the day, including physical exercise like walking, the faster your metabolism works. Building consistent daily habits that include more movement, whether taking a walk during lunch or walking for 30 minutes after work in the evening, will contribute to a faster metabolism.

A high or faster metabolism means your body will burn calories during movement and while your body is resting. This is an ideal scenario for weight loss because your body is still working even when you’re no longer exercising. Weight loss is much more attainable if you burn more calories than you consume.

Sustainable and low-impact

Many choose to add walking to their exercise routine because it’s low impact and easy on the body. Regular walking at a moderate pace usually doesn’t add any strain to your muscles or joints, particularly the hips, ankles, and knees.

Walking offers minimal risk of injury, unlike other high-intensity cardio exercises like cycling or running. It’s also a more sustainable method if you want to work out for longer periods of time; you can walk longer or farther without overexerting yourself.

Many individuals add a few walks a week to their workout routine as a way to let their body recover; you control the pace, the distance, and the duration, making it a very sustainable form of exercise, whether you’re power walking or just strolling with a friend or your dog.

Cardiovascular health

The body needs cardiovascular exercise to maintain a robust and healthy heart. Engaging in regular cardio exercise can lower blood pressure, reduce the risk of disease, and even reduce inflammation throughout the body, all by strengthening and exercising the heart!

Cardiovascular exercises range from high intensity like jump rope, boxing, rowing, and running to lower impact exercises like hiking, walking, and swimming. You don’t have to push your body to its limits to get a great cardio workout. Moderate or brisk walking is a fantastic way to get the heart pumping, improve blood flow, lower cholesterol, and much more.

General health and well-being

Whether you’re on a committed weight loss journey or just looking for new exercises to maintain your weight, physical exercise, like walking, is a great way to take care of the body and the mind.

Some people take long walks to free their thoughts, gain new perspectives, and even meditate. By getting fresh air or a change of scenery, many experience a change in outlook or even the “runner’s high” without engaging in high-intensity cardio exercises.

It’s no secret that physical exercise of any kind can significantly impact your mood. During exercise, the human body releases adrenaline and endorphins, which are known to improve mood and stress levels.

Additionally, regular physical exercise like walking has been shown to improve the quality of sleep, particularly for middle-aged and older adults.

Experts recommend anyone over 18 get at least 7 hours of quality sleep every night so the body can recharge and repair itself so you can wake up energized, healthy, and ready to take on the day!

As you add more cardio workouts to your weekly schedule, ensure you stay hydrated. As your body works harder and sweats more during your workouts, your body will need more water to function properly. As a general rule of thumb, experts recommend men drink 125 ounces of water each day, and women drink 91 ounces per day.

How many calories does walking burn?

According to Mayo Clinic, 30 minutes of brisk walking can help you burn at least 150 calories per day. The farther you go and the faster your speed is, the more calories you’ll burn along the way.

Many wearable devices will help you track these metrics, regardless of where you are on your journey to wellness. Whether you’re training for an event or setting a weight loss goal for yourself, having a supportive device can help you achieve those goals by tracking your progress along the way.

How often and how far should I walk?

Depending on your current physical health and if you want to lose weight by walking, most experts recommend starting with slow-paced walks for a short, manageable distance.

Start by going for 2–3 walks per week for 15 to 20 minutes at a time. You can add time and distance to your walks as you build endurance and muscle strength. Before you know it, you'll be walking 30 minutes a day and loving every minute of it.

Keep your health a priority with the Evidation app

Walking is a low-impact and enjoyable way to add physical exercise to your daily routine. Is weight loss from walking possible? Most definitely! Starting small and creating healthy, sustainable exercise habits takes time and commitment, but with apps like Evidation in your corner to track your progress, you’ll be achieving your goals in no time.

The thought of receiving a breast cancer diagnosis can be crippling, and many women wonder if there are any ways to prevent breast cancer that are within their control.

While breast cancer risk factors are genetic and out of our control, a few protective factors do reduce the risk of breast cancer.

Understanding these strategies and taking the necessary steps to ensure you’re living a healthy life is the most effective way to reduce the risk of getting breast cancer.

What are the risk factors and main causes of breast cancer?

When abnormal cells develop in the breast and multiply, breast cancer forms. While researchers don’t know for sure why abnormal cells develop, they have pinpointed a few risk factors and the main causes of breast cancer. These include:

Age

Older age is the primary risk factor for breast cancer. According to Cancer.gov, women over 30 have a 1 in 200 chance of being diagnosed with breast cancer in the next 10 years, while women over 70 have a 1 in 25 chance.

Sex

Women are much more likely to get breast cancer than men, although male breast cancer does happen. The American Cancer Society estimates that over 297,000 women will be diagnosed with breast cancer in 2023, with around 2,800 men receiving the same diagnosis.

Genetics

Women with a history of breast cancer in their immediate family, including their mother, sister, or daughter, have an increased risk of receiving a breast cancer diagnosis.

Lifestyle choices

Your lifestyle choices significantly impact your risk of breast cancer. Smoking and drinking alcohol are breast cancer risk factors, particularly if you consume regularly or have been a smoker for many years.

Obesity is another risk factor for breast cancer. Fat tissue is known to contain excess amounts of estrogen, a hormone that is associated with breast cancer, when high levels are present in a woman’s body.

How to Reduce Risk of Breast Cancer On Your Own

When it comes to breast cancer, many factors are out of your control. However, you can play a role in reducing your risk and potentially catching cancer early by doing the following:

Pay attention to your body

You know your body better than anyone, so pay attention to any signs or symptoms that may present themselves. If your breasts or skin change in appearance or you detect a lump, consult your doctor immediately.

Stay on top of mammograms and breast checks

Breast cancer screening recommendations are helpful ways to prevent disease and are highly effective at detecting breast cancer. These screenings include mammograms, breast ultrasounds or MRIs, and clinical breast exams performed by a doctor or nurse.

Know your family history

Some forms of breast cancer run in families, so knowing your immediate family history is critical to reducing your risk. Some people opt for genetic testing to know with more certainty what their risk is.

5 Ways to Prevent Breast Cancer With Your Lifestyle Choices

Genes, lifestyle choices, and your environment can all increase or decrease the risk of getting cancer at some point in your life. This applies to all kinds of diseases, not just breast cancer.

Fortunately, we have some control over our lifestyle choices and can take steps to make modifications as necessary to improve our health. Here are five meaningful improvements you can make in order to decrease your risk of getting breast cancer.

Eat Healthy

A healthy diet won’t actually prevent breast cancer from forming, but it can help lower the risk of getting it by ensuring your body is healthy and functioning properly by boosting your immune system.

Be sure to eat plenty of fruits and vegetables, whole grains, and lean protein. Avoid saturated fats, processed meats, and charred foods. 

For women who are genetically predisposed to breast cancer or have already beaten the disease, any steps to feel proactive with their health is often very helpful. As Evidation research suggests, nearly 23 percent of surveyed individuals reported feeling fearful and concerned about their cancer returning. Research shows that low-fat diets may reduce the risk of first-time breast cancer as well as recurring breast cancer, which is encouraging for those women who have already received a breast cancer diagnosis and those who are in remission. 

‍Stay Active

Research shows that women who are active and get regular physical exercise have a 10-20 percent lower risk of getting breast cancer, particularly in postmenopausal women.

We already know that staying active is essential to maintaining peak physical health at any age and can drastically improve overall health. Staying active has many benefits; you just have to find an activity you enjoy doing and make it a consistent habit in your life.

Adults need 150 minutes of moderately intense physical exercise per week to stay healthy and at least two days of strength training (working out with weights).

Avoid Smoking and Drinking

When a person inhales smoke from a cigarette, they are breathing harmful toxins into their lungs. These toxins include cancer-causing chemicals, increasing the risk of getting breast cancer at some point in their lives, especially when compared to people who have never smoked.

It’s never too late to kick the habit if you're a smoker. Doing so can decrease your risks of getting breast cancer and other diseases, including lung cancer or heart disease.  

Drinking alcohol is much more widely accepted, and some forms, like red wine, are often recommended for improving heart health. Alcohol is still a toxin and should be enjoyed in serious moderation.

Alcohol increases the levels of estrogen and other hormones in a woman’s body, which are associated with certain types of breast cancer.

Most experts recommend having two or fewer alcoholic drinks per week to reduce the risk of breast cancer.

Maintain a Healthy Weight

Carrying excess weight can significantly increase a woman’s breast cancer risk before and after menopause.

If you are overweight, work with your doctor to develop a plan to lose weight healthily. Plan to add physical exercise to your weekly schedule and start swapping out any unhealthy foods with clean options that will give you more energy and help you burn more calories. Eating healthy, balanced meals can help you feel satisfied and full to avoid snacking until your next meal.

Breastfeed

If possible, breastfeed your children for up to one year to reduce your risk of breast cancer.

During breastfeeding, the body loses breast tissue, which can remove cells with potential DNA damage. Breastfeeding also changes the hormones (like estrogen) in a woman’s body and reduces your contact with them. Many of these hormones promote breast cancer growth.

August is National Immunization Awareness Month, and this is a great time to shed some light on the truth about vaccines. Just like you can use a health tracker to predict a coming illness, vaccines can help people potentially prevent illness in the first place, or in the case of the flu and COVID-19 vaccines, reduce the impact of the illness. As we enter this critical month, the team at Evidation wanted to dig into the importance of vaccines for individuals and the community as a whole.

Recognizing the importance of vaccination

Since the discovery of vaccines, some of the world's deadliest viral and bacterial illnesses have been practically eliminated or greatly reduced globally. The World Health Organization states there are 25 illnesses with current vaccines. Several diseases commonplace a century ago are now pragmatically gone, including life-altering diseases like polio, hepatitis A, and tetanus.

In other words, vaccines save lives. National Immunization Awareness Month is an excellent time to draw attention to the importance of vaccination, so more people will get on board and get vaccinated.

Debunking popular vaccine myths

Sadly, vaccines have several myths surrounding them. Like all good myths, they have a measure of truth or speculation. Here are the four most popular and the reality behind them:

1. Herd immunity is enough

Herd immunity occurs when the majority of a population is vaccinated, which reduces the chances of an outbreak. Herd immunity protects the most vulnerable populations, like infants or pregnant individuals, who can't get vaccinated. So there's a measure of truth here. But if too many people rely on herd immunity, it won't work anymore. Also, the number of vaccines needed to reach this point is high. According to Yale, herd immunity against measles doesn't start until 95% of the population gets vaccinated. If too many people buy into herd immunity for their own protection, it won't exist.

2. Vaccines contain harmful ingredients

Again, there's a measure of truth to this myth. According to the American Academy of Allergy, Asthma & Immunology, some vaccines contain ingredients that can be harmful in high doses, such as thimerosal. However, manufacturers are moving away from these ingredients when possible, and the amount in the vaccine is very small. In fact, you're naturally exposed to mercury, the main toxin in thimerosal, every time you drink milk or eat fish, and in much higher concentrations than what's in the vaccine.

3. Vaccines cause autism

One of the biggest popular claims circulating today is that vaccines cause autism. For some parents of children with autism, looking for a cause can become their mission.

This myth became popular in 1998 when Andrew Wakefield published a case study in the Lancet. It suggested that the MMR vaccine may trigger behavioral regression in children. Sadly, many considered this study fact, even though it only studied 12 people, had poor parameters, and was entirely speculative. In fact, 10 of the 12 co-authors of the paper retracted their interpretation of the results, but the misinformation was already out there.

In 2012, the National Academies performed a new study to determine if vaccines can trigger autism. It found that vaccines were very safe. In 2013, the CDC added to that study and found that the number of antigens from vaccines was the same between children who were on the autism spectrum and those who weren’t. Based on these two studies, the CDC has stated that vaccine ingredients don't cause autism.

4. I don't need vaccines against normal childhood illnesses like the flu or chickenpox.

For many people, getting vaccinated against something like the flu or chickenpox, which isn't often life-threatening, feels unnecessary. Yet, even though most people have mild symptoms of these illnesses, they can be very dangerous for some. In the United States, between 140,000 and 710,000 people are hospitalized yearly from flu complications, and between 12,000 and 52,000 die. You don't know if you or your child are in the "high risk" category or not. With the low risk of vaccines, it's a health measure worth taking.

Vaccination across the lifespan: Tailoring recommendations for different age groups

Vaccines are safe, but using a vaccine schedule to deliver them at the recommended ages helps protect children from uncomfortable vaccine reactions. It also ensures that they get as many vaccines as possible by the time they are in preschool.

The CDC has a recommended vaccine schedule that looks like this:

Birth to six months

In the first six months of life, babies should receive their first doses of:

• Hepatitis B
• Rotavirus
• DtaP
• Hib
• Pneumococcal conjugate
• Inactivated poliovirus

Six months to two years

Between six months and two years, toddlers need several boosters for the vaccines they've already received, as well as these:

• COVID-19
• Flu vaccine
• MMR
• Chickenpox
• Hepatitis A

Later childhood and teenage vaccines

After the initial round of vaccines, children need the flu shot and COVID-19 vaccine annually. In addition, they'll need the following:

• HPV vaccine – First dose around age 11
• Meningococcal disease – First dose around age 11
• Tdap – First dose around age 11

Vaccines for adults

Adults need annual vaccines against COVID-19 and flu. In addition, they will need the Tdap vaccine on occasion to protect against tetanus. Adults who travel outside of the United States may need additional vaccines against illnesses still prevalent globally. Finally, adults need a booster for their HPV vaccination by age 26. At college age, young adults may need an MMR booster. Older adults benefit from the pneumonia and shingles vaccines. 

The challenge of vaccine equity

Some of the benefits of vaccination, like herd immunity to protect the most vulnerable, don't work if people can't access vaccines. According to the WHO and other global health organizations, countries with low economic status often struggle to obtain and distribute vaccinations. Even within the US, people who don't have health insurance may not have the funds to get vaccines for their children or themselves.

To combat this, in 2020, the CDC pioneered the Partnering for Vaccine Equity program, which increased funding for adult immunization programs. While more work needs to happen, this has gone far in increasing vaccination rates in underserved communities.

COVID-19 vaccination

The COVID-19 vaccine is the newest vaccine to make global headlines, as we're just a few years past the height of the pandemic. Since its introduction at the end of 2020, at least 80% of the US population has received at least one dose of the vaccine. This has prevented over 18 million hospitalizations and 3 million potential deaths.

This vaccine shows the power of working fast to protect against a global threat. Its swift development and free administration helped curb the effects of the pandemic. Continued use of the COVID-19 vaccine and boosters in the future may help keep new variants at bay.

What's the bottom line? Immunizations are safe and provide protection for our kids and the community at large. During National Immunization Awareness Month, take a moment to check your vaccine history and make sure you're up-to-date.

If you or someone in your family is living with asthma, you may wonder what caused the disease, and whether it can be passed on genetically. Here, we'll explore the symptoms of asthma, the genes that are associated with an increased risk of asthma development, and the treatments that can help control asthma symptoms.

What is asthma?

Asthma is a respiratory disorder in which airways become inflamed and cause recurring breathing difficulties. Sometimes, asthma episodes are referred to as asthma attacks.

During an asthma attack, the muscles around the airway tighten, making it difficult for the person experiencing the attack to breathe. Over time, this can have a compounding effect, as the tightening and strengthening of the muscles around the airways can cause the muscles to become larger, resulting in additional breathing difficulty due to airway compression.

Many people who have asthma experience mild symptoms regularly, and more severe symptoms less frequently. Asthma can flare up with seasonal changes, exercise, and illness, including the flu. Over time, people who have asthma often learn to understand their triggers, allowing them to utilize self-care and medication to prevent an attack.

Asthma symptoms can include:

• A feeling of tightness or itchiness in the chest
• Extreme sensitivity to environmental irritants and/or allergens
• Shortness of breath, even while performing everyday activities
• Wheezing (a whistling or squeaking sound in the chest that occurs while inhaling or exhaling)
• Excessive coughing (often flares up at night)

Is asthma genetic?

Asthma is a complex condition. Research shows that asthma is caused by both environmental and genetic factors. People who have a close relative who has asthma are more likely to develop asthma, but there's no guarantee. Research shows that people who are genetically likely to develop asthma develop the condition in about 75% of cases.

Genes and asthma: what you need to know

There is not a single gene that causes asthma, but there are genes that make it more likely that a person will develop the condition.

Genes associated with the development of asthma include ADAM 33, PHF11, DPP10, GRPA, and SPINK5. Since asthma has both environmental and genetic factors, it can be helpful to know if a person is likely to develop the condition.

While asthma development cannot be totally prevented, parents who have asthma can take steps to make it less likely that their child will experience severe symptoms. Reducing exposure to allergens, encouraging regular exercise, and working closely with a pediatrician to reduce the risk of severe symptoms can all help a child who is likely to develop asthma breathe easily.

Allergies can also make it more likely that a person will develop asthma. Allergies to dust mites, cats, dogs, cockroaches, fungi, and mold may be a predictor of an asthma diagnosis.

Genetic risk scores: predicting asthma susceptibility

Some asthma develops solely due to environmental factors, so it can be tough to correctly determine a person's likelihood of being diagnosed with the condition. According to the Centers for Disease Control, a person who has at least one parent with asthma is up to six times more likely to develop the condition.

Male children are more likely to develop asthma than female children, as 8.3% of males are diagnosed with childhood asthma, compared to just 6.7% of females. Researchers aren't sure what role sex plays in this difference. And, unfortunately, lack of research on childhood asthma rates for intersex individuals means we don’t have a full picture. 

As time goes on, however, there's a shift--among adults who were diagnosed with asthma as children. 9.8% of females still have the condition as adults, and 5.5% of males still have the condition as adults. As with children, there is unfortunately a gap in research when it comes to the incidence of asthma in intersex adults.

There are also racial differences when it comes to the development of asthma. According to Lung.org, "Blacks and American Indian/Alaska Natives have the highest current asthma rates compared to other races and ethnicities. In 2018, Black people (10.9%) were 42 percent more likely than white people (7.7%) to have asthma. Hispanics (6.4%) and Asians (4.0%) had lower current asthma prevalence rates than other ethnic groups."

Household income is also correlated with the likelihood of an asthma diagnosis. Of people who live in a home with an income level that falls below the poverty threshold, 11% are typically diagnosed with asthma, according to Lung.org.

Exposure to cigarette smoke and weight can also contribute to the development of asthma. People who weigh more may be more likely to develop asthma and tend to have more days during which they experience severe asthma symptoms. Weight can also play a role in how well someone is able to manage their asthma symptoms with medication. 

Asthma treatment

While it can be scary to get an asthma diagnosis, it's the first step toward learning more about how you can best support your (or your child's) health.

Left untreated, asthma can turn deadly. It's important that you work closely with your doctor to ensure that you're controlling the condition.

For many people, a combination of asthma medication and lifestyle can help ease symptoms. Your doctor may recommend that you take a daily asthma medication to keep your symptoms in check, while also keeping a quick-relief medication on hand for flare-ups.

Asthma medications are typically in the form of an inhaler or a pill. Some people may also keep a nebulizer at home, which is a machine that vaporizes asthma medication, allowing it to quickly get into the body in large doses. This is the same machine that's often used in the emergency room to help quell an asthma attack.

Your doctor may also recommend lifestyle changes to ease the symptoms of your asthma. These may include exercising regularly, losing weight, quitting smoking, avoiding certain allergens, and making dietary changes.

Cardiovascular diseases (CVDs) cause 17 million deaths globally every year, making it the leading cause of death around the world. 

The cardiovascular system—which includes your heart and blood vessels—distributes oxygen through the body and removes waste. Every cell in the body depends on this process to run smoothly. 

Your cardiovascular system plays a key role in your overall health and longevity. In today’s article, we’ll share three tips to improve your cardiovascular health. 

Definition of cardiovascular health

Your cardiovascular health refers to the health of your heart and blood vessels, according to the National Association of Chronic Disease Directors.

Many people experience cardiovascular health issues at some point during their lives. The heart and blood vessels are complicated, and it’s easy for small issues to grow into something larger and more concerning over time. Some people are more genetically prone to heart issues, while others develop heart problems due to environmental and lifestyle factors. Often, it’s a combination of genetics and lifestyle that lead to cardiovascular health problems. 

Lifestyle issues that can contribute to cardiovascular problems include: 

• Smoking
• Chronic stress
• Sedentary lifestyle
• High blood pressure
• High cholesterol
• Diabetes

When people are aware that they’re living with conditions that make them more likely to develop cardiovascular issues, they’re able to take steps toward improving their heart health, often avoiding invasive procedures. It’s important that you work closely with your doctor to manage your health to avoid heart damage.

While all cardiovascular diseases (CVDs) involve the heart and/or blood vessels, there are several different types of CVDs, including: 

• Deep vein thrombosis and pulmonary embolism: Issues involving blood clots that develop in the legs, which later may dislodge and move to the heart and/or the lungs. 
• Congenital heart disease: A birth defect that affects the way the heart functions. People with congenital heart defects may be asymptomatic, or may require surgery to repair structural heart issues. 
• Coronary heart disease: A common type of heart disease that affects the blood vessels that direct blood to the heart. 
• Peripheral arterial disease: A type of heart disease that affects blood vessels that supply blood to the arms and legs. 
• Cerebrovascular disease: A type of heart disease that affects the blood vessels that supply blood to the brain. 
• Rheumatic heart disease: Damage caused to the heart by rheumatic fever/streptococcal bacteria.

Some people who are at risk for cardiovascular issues never develop a problem, while others who are at low risk experience cardiovascular issues. Healthy lifestyle choices, including getting regular exercise, eating a healthy diet, and tracking your health data, can go a long way in helping you ward off a cardiac event. 

Now, let’s take a look at steps that you can take to boost your cardiovascular health. 

How to improve cardiovascular health

If you’ve recently learned that you’re at risk for the development of cardiovascular disease, it’s important to take the steps necessary to boost the health of your heart. While it can be scary to get the news that your health is at risk, understanding and following through with lifestyle changes can go a long way in restoring your heart’s health, boosting your energy, and helping you rest assured that you’re doing all you can to help you live a longer, healthier life.

Diet, exercise, and lowering stress levels can all help your heart stay healthy. You’ll also want to consider staying away from substances that can cause heart damage, including alcohol and tobacco. Here, we’ll take a closer look into how certain lifestyle changes can help your heart stay strong.

Diet: foods for a healthy heart

‍

‍Why is diet important?

If you’re researching how to improve cardiovascular health, you likely already know the importance of choosing foods for a healthy heart. Cutting out processed and fried foods can be a great choice to help your heart get strong, but eating foods for a healthy heart isn’t just about what you have to give up–it’s also about finding new favorites. Here, we’ll take a look at both what you’ll want to cut down on in your diet to boost the health of your heart, as well as delicious new favorites you’ll want to add as you work to get healthy. 

Certain nutrients, foods, and minerals can affect how well the cardiovascular system functions. While the tips below are a good fit for most people who’re working to improve their cardiovascular health, it’s important that you talk with your doctor before making changes to your diet, especially if you’ve been informed that you’re experiencing cardiovascular disease. Your doctor will be able to work with you and monitor your progress to discover what type of nutrition plan is the best fit for your heart health needs. 

Excess sodium can cause high blood pressure, which can lead to heart disease. One study showed that eating a diet high in sodium may cause water retention—straining the heart as it works harder to move extra fluid through the body. It’s recommended most adults limit their intake to 1,500 mg of sodium a day. 

Consuming too many unhealthy fats (saturated and trans fats) can cause high cholesterol, which increases the chance of coronary artery disease. When cholesterol is too high, plaque can build up in the arteries—putting you at higher risk for heart attack and stroke. 

Try avoiding too many unhealthy fats like fatty meats, dairy, and fried foods. Instead, do your best to eat good fats like olive oil, avocados, nuts, and seeds.

So what foods and nutrients support cardiovascular health?

High-fiber diets have many benefits, like:

• Controlling blood sugar levels
• Reducing your risk of cardiovascular disease (CVD) 
• Maintaining and achieving a healthy weight
• Lowering total blood cholesterol levels by lowering “bad” cholesterol levels.

Whole grains—or grains that haven’t been refined to remove their bran and germ—are a good source of fiber and other nutrients that help regulate blood pressure and boost heart health. Foods like oatmeal, whole-wheat bread, and whole-grain pasta are great options. Or choose whole grains like barley, quinoa, buckwheat, and brown rice instead of refined grains like white rice or things made with white flour.

Vegetables and fruits are both low in calories and rich in fiber—and have other nutrients that may help prevent CVD. Load up on red, yellow, and orange produce like carrots, red peppers, and tomatoes; they contain carotenoids and vitamins that can nourish heart health. Berries are full of heart-healthy phytonutrients—try throwing some in a smoothie or your morning oatmeal. 

Exercise for heart health

Your heart is a muscle just like your biceps and calves—exercise can strengthen it. If it’s been awhile since you last hit the gym, got out for a walk, or sit down to do some stretching at the end of the day, don’t worry–there’s no need to train for a marathon to boost the health of your heart (unless that’s your thing). Simply getting active a few times a week can work wonders to help get your heart health back on track, one workout at a time. No matter what your limitations, there are movement strategies you can use to begin the process of strengthening your body–and your heart.

The benefits of exercise include:

• Lower blood pressure. Exercising can help lower blood pressure and slow your resting heart rate.
• Reduced inflammation. As bodily systems are activated through exercise, the body adapts and reduces chronic inflammation. 
• Healthy weight. Being overweight can put stress on the heart and cause buildup in arteries, increasing the risk for heart disease and stroke. Exercise, when paired with a healthy diet, can help to maintain a healthy weight.
• Strengthened muscles and bodily systems. A combination of aerobic exercise and strength training is recommended to improve your muscles' ability to draw oxygen from the blood. This reduces the need for your heart to work harder to pump more blood to muscles.
• Reduced stress hormones. Exercise reduces stress hormones, which put a burden on the heart. Many studies also suggest that people who exercise consistently are less likely to suffer from a sudden heart attack. 

If you’re looking to exercise more, a combination of aerobic exercise and resistance training has been shown to be best for heart health.

‍Aerobic exercise, also fittingly called “cardio,” relies on breathing to fuel the activation of large muscle groups for a sustained period of time. Aerobic literally means “with oxygen.” It improves circulation to lower blood pressure and heart rate. It can also help your heart pump stronger. Ideally, for healthy individuals, a routine of 30 minutes a day, 5 days a week is best. But beginners should take their time and work their way up. If you are managing health conditions or haven’t exercised in a while, be sure to talk to your healthcare provider about what exercise program is right for you. Aerobic exercises include:

• Cycling / arm cycling
• Running
• Jump rope
• Swimming
• Brisk walking

‍Resistance training, also known as strength training, has a more direct effect on body composition. Resistance training grows and strengthens muscle mass while reducing body fat. One study found that one hour per week of resistance training also reduced a specific type of fat around the heart, potentially reducing risk factors for cardiovascular disease. Some examples of resistance training include: 

• Weight machines
• Resistance bands
• Free weight workouts (dumbbells and barbells)
• Body weight exercises (pushups, chin-ups, squats)

Exercise is a powerful practice to support cardiovascular health—especially in combination with a healthy diet. If possible, make a plan to get moving this week.

If you struggle to stay on track when it comes to exercise, you aren’t alone. Teaming up with a friend or family member who’s also working to improve their habits can be a great way to stay the course when motivation wanes. Setting a regular time to walk or do other exercise that allows you to still have a conversation with a friend or a group can help you stay on track, even on days when you’d rather hit the couch than lace up your sneakers.

Healthy habits for heart

Habits can also play a big role in the health of your heart. 

Sticking to habit changes can be tough, and it’s important that you set achievable goals to help you stay motivated as you work to make small changes that will impact your life in a big way. 

‍Higher stress levels may cause higher blood pressure—amplifying your risk of heart attack and stroke. 

To reduce stress, find time for hobbies that help you relax. Practices like meditation can also help reduce stress. Or try reaching out to a loved one to talk and catch up.

Don’t skip out on regular checkups. Finding potential health issues early can help you get the right treatment quickly and avoid any unnecessary complications. 

‍What are habits to avoid?

‍Alcohol and smoking can lead to poor heart health. 

According to the CDC, smoking causes around 1 in 4 deaths from CVD. Chemicals found in tobacco smoke cause cells that line blood vessels to become swollen and inflamed. This narrows the blood vessels—leading to cardiovascular conditions.

Excessive drinking can lead to heart failure, high blood pressure, or stroke. It can also contribute to cardiomyopathy—a disorder that affects the heart muscle. Alcohol is high in calories too. Excessive drinking can lead to weight gain and becoming overweight, a risk factor for cardiovascular disease.

Maintaining and improving cardiovascular health starts with your lifestyle. If you can eat better, exercise regularly, and avoid bad habits you may begin to build a more robust cardiovascular system. Adopting a new lifestyle can be challenging, but making small changes on a daily basis can help you establish healthy habits to improve your overall health and well-being. By taking things one day at a time, you can gradually build a foundation of healthy behaviors that will benefit you in the long run.

If you learned anything new, share this with a friend or family member who could benefit from learning about these tips for better cardiovascular health.

As every migraine sufferer knows, migraines aren't just headaches. Migraines cause debilitating pain that can make it impossible to get through the day--much less be productive.

June is National Migraine and Headache Awareness Month. At Evidation, we know many people in our community deal with migraines and headaches, and we're working to provide you with the information you need to come out on the other side following a migraine.

What causes migraines?

Many migraine sufferers work to pinpoint their triggers to avoid a future migraine. Unfortunately, researchers still aren't completely sure what causes migraines to occur. There’s likely a combination of factors at work, including changes in blood vessels, nerves, and chemicals.

While the exact cause of migraines has yet to be determined, many people find that certain health and life circumstances make migraines more likely to occur.

Common migraine triggers include:

• Hormonal changes throughout the menstrual cycle (people who menstruate are three times more likely to experience migraines)
• Stress (both chronic and acute)
• Fatigue
• Certain foods and drinks, including caffeine, alcohol, and chocolate

Knowing your triggers can help you and your doctor develop a plan to stop migraines in the future. Many people who live with migraines find it helpful to keep a journal regarding their symptoms. This can help you and your healthcare professional to work together to find patterns, allowing you to develop a plan that makes it less likely that you'll experience migraines in the future.

What does a migraine feel like?

For many people, a migraine involves severe headache pain. It's often only felt on one side of the head. When people are experiencing a migraine, they might be extremely sensitive to light and sound and may experience gastrointestinal symptoms (such as vomiting) due to headache pain. Some people experiencing a migraine find it difficult to fully open their eyes due to light changes (similar to the feeling many experiences following eye dilation at an eye appointment).

There are three types of migraines, and the type of migraine you experience can determine your symptoms. Some people only ever experience one type of migraine, while other people find that their migraines change over time.

The three most common types of migraines include:

• Migraine with aura: In this type of migraine, warning signs are experienced before the pain sets in. Many people experience an aura, which can include the appearance of flashing lights, blind spots in the vision, patterns in the vision (such as dots or repeating black marks, and tunnel vision).
• Migraine without aura: This type of migraine only involves severe pain without the warning signs associated with aura.
• Silent migraine: Only the aura portion is experienced in a silent migraine, and head pain does not occur.

Migraines are different from person to person. Suppose your symptoms are more severe than normal, or you're experiencing new and concerning symptoms (such as paralysis, weakness, slurred speech, a level of pain you haven't experienced before, fever, double vision, confusion, seizures, or a rash). In that case, it's important to go to the emergency room for help, as these symptoms can be signs of a more serious condition.

How long can a migraine last?

The exact length of a migraine can depend on several factors. Some people find that their migraines always fade within a certain time, while others experience more variability. Typically, a migraine lasts between four hours and three days.

The frequency of your migraines is important to mention to your healthcare provider. If you experience more than a few days of migraines per month, you may be a candidate for medicine that can stop migraines from occurring in the first place.

Migraine treatments

Are you searching for information on how to relieve a migraine? Unfortunately, there's no cure for migraines--yet. Researchers are working to determine the exact cause of migraines, so they can develop treatments to help people suffering.

Thankfully, some medicines can treat the symptoms of migraines, allowing you to get back on your feet faster following an attack.

Many people find that painkillers are helpful when experiencing a migraine. Taking medicine like Tylenol or Advil as soon as you notice the first symptoms of a migraine (such as an aura before the pain sets in) can help minimize symptoms, even if you can't eliminate them. If you find that you're experiencing regular migraine attacks that leave you reaching for the medicine cabinet, be sure to talk with your doctor, as they may be able to provide you with different, more effective pain management options.

Triptans (such as Imitrex, Zomig, Amerge, and Maxalt) are prescription medicines that can help with brain changes thought to occur before a migraine. You may find that these medicines help to stop your migraine faster than painkillers alone.

If you deal with nausea when you have a migraine, your doctor may prescribe you anti-nausea medications to help you get the rest you need to get through a migraine attack.

In addition to pharmaceutical treatments, there are some at-home remedies that many people find helpful for alleviating migraine symptoms. Lying down in a quiet, dark room with a cool cloth on your head may help with symptoms. Some people also find that stress reduction techniques (like deep breathing) can help to alleviate migraine symptoms.

Many researchers generally agree that personality is made up of 5 unique traits: 

• Conscientiousness (organization, productiveness, responsibility)
• Extraversion (sociability, assertiveness; its opposite is Introversion)
• Agreeableness (compassion, respectfulness, trust in others)
• Openness (intellectual curiosity and creative imagination)
• Neuroticism (tendencies toward anxiety and depression)

Some people may have very high or low levels of a trait, but most of us fall somewhere in-between. 

What is openness?

‍Openness describes how intellectually curious, imaginative, and appreciative of art and beauty someone is.

• Those with high levels of openness are generally open to new activities and ideas. They tend to be creative, curious, and sensitive to art and beauty. 
• Those with low levels of openness tend to be traditional, practical, and like to stick with conventional ways of doing things. They prefer the familiar over the new, and the concrete over the abstract. 

Why does openness matter for health and health decision-making?

Although openness doesn’t strongly or consistently relate to health, people can still use their understanding of their level of openness to change their health behaviors and make them more likely to stick.

We recently offered our members the opportunity to take a survey to see where they fall on the spectrum for openness. If you’re an Evidation Member who took the survey and received your openness results, read on to understand what a high or low score may mean for your health. If you’re not a member and want to see results like these, download the Evidation app.

I scored high on openness. What could this mean for my health?

If you’re high in openness, and thus enjoy exploring new activities and ideas, you may be more motivated to stick with a varied physical activity schedule than a familiar routine. 

If you have a hard time turning healthy behaviors, like exercise, into habits, try adding variety. For example you may try… 

• Going for a walk at a new spot
• Creating a new music playlist to run to
• Signing up for an exciting race you need to train for 

Finding new ways to fulfill your intellectual interests–like music, art, or something else–may also help boost your well-being. You may find these hobbies to be especially helpful when you’re feeling stressed.

I scored low on openness. What could this mean for my health?

If you scored low in openness, you may find it easier to stick with familiar exercise routines or healthy recipes than it is to try new ones. 

If you haven’t found healthy behaviors that work for you, try a few out until you find one you like, and make it a habit, such as…

• Making a healthy taco dinner every Tuesday
• Aiming to walk with a friend every day at the same time 
• Going to the same evening yoga class each week

Though personality traits are only one small part of your health and well-being, learning more about yourself may help you to find healthy routines and behaviors that stick.

From hyperthyroidism to hypothyroidism to Hashimoto's disease, it can be tough to understand all of the different conditions that can affect your thyroid gland. Here, we'll take a look at the differences between hypothyroidism and hyperthyroidism, including symptoms and treatments.

The thyroid gland: supporting your body, one system at a time

Hormones produced by the thyroid include thyroxine, triiodothyronine, prohormone, and calcitonin. These hormones work to regulate your body's growth, development, and metabolic rate.

If you're generally healthy, you probably don't spend much time thinking about your thyroid. But if the gland begins producing too much or too little thyroid hormones, many health symptoms can appear. Changes in energy levels, weight, heart rate, reproductive health, and skin health can all occur when thyroid hormone levels fall out of balance.

Cancer can also develop in the thyroid, interrupting a variety of bodily processes. Signs of thyroid cancer can include a lump or nodule in the front of the neck (where the thyroid is located), voice changes, neck and throat pain, trouble swallowing, and hormonal changes (such as acne and unusual growth of body hair).

If you’re experiencing any of these symptoms, be sure to talk to your healthcare provider.

What are the symptoms of thyroid disorder?

As mentioned, the thyroid is a key player in producing and regulating your body's hormones. If you're experiencing a thyroid disorder, such as hypothyroidism or hyperthyroidism, it's likely that you'll notice some changes related to your energy and hormones.

Symptoms of thyroid disorder are often attributed to aging and other factors. If you're noticing symptoms that could be indicative of a thyroid problem, it's important to talk to your doctor about the changes you've noticed.

Symptoms that may indicate a thyroid disorder include:

• Changes in mood, including anxiety or depression
• Sleep changes, such as excessive sleepiness
• Weight loss or weight gain that cannot be explained by lifestyle factors
• Changes in energy levels, especially feeling tired even after getting a normal amount of sleep
• Body changes typically related with teenage hormones, such as an increase in body hair and acne

If you're experiencing symptoms that could indicate a thyroid condition, your doctor will be able to prescribe tests to find the root cause of the issue. Thankfully, medication and lifestyle changes can be hugely helpful in alleviating many of the symptoms associated with a thyroid disorder.

What's the difference between hypothyroidism and hyperthyroidism?

Both hypothyroidism and hyperthyroidism mean that something isn't quite right with the thyroid.

The prefix "hyper" means "more"--when a person is experiencing hyperthyroidism, their thyroid is producing a surplus of hormones.

The prefix "hypo" means "less"--when a person is experiencing hypothyroidism, their thyroid isn't producing enough hormones.

Hypothyroidism symptoms

Hypothyroidism is a condition in which the thyroid does not make enough hormones. This can cause the body processes to slow down. People with certain conditions, including diabetes, lupus, and Celiac disease, are more likely to develop hypothyroidism than people who do not have these conditions.

Symptoms of hypothyroidism can include:

• Chronic fatigue
• Fertility problems
• Struggles to tolerate cold temperatures
• Slow heart rate
• Depression
• Muscle and joint pain
• Weight gain that can't be explained by changes in diet or lifestyle

Like the symptoms of hyperthyroidism, many of the symptoms of hypothyroidism are often thought to be associated with aging, mental health issues, and other non-hormonal conditions. Hypothyroidism tends to develop slowly. If you notice that you're developing symptoms of hypothyroidism, it's important that you ask your doctor to check your thyroid hormone levels.

Hyperthyroidism symptoms

If your body has an excess of thyroid hormones, it can speed up your metabolism to the point where you experience negative health effects.

Symptoms of hyperthyroidism can include:

• Losing weight despite efforts to maintain or gain weight
• Never feeling satiated despite eating more food
• Rapid heartbeat or heart palpitations
• Anxiety
• Hand tremors
• Eyes appear to bulge forward out of sockets

Simply put, hyperthyroidism speeds up your body to a point where it can be tough to function effectively. Many people who have hyperthyroidism believe that their symptoms--especially anxiety--are within their control. With hyperthyroidism, medication is often needed to regulate hormone levels.

It’s important to note, that while most people with hyperthyroidism lose weight, about 10% actually gain weight, which can lead to difficulty getting diagnosed. So, if you’re experiencing other symptoms of hyperthyroidism but are gaining weight, be sure to talk to your doctor. 

Hypothyroidism treatment

There are several approaches to treating hypothyroidism. Your endocrinologist (a doctor who specializes in hormonal issues) will work with you to determine the right treatment approach for you. Your doctor may recommend diet and lifestyle changes along with synthetic thyroid medicine known as levothyroxine. After about a month and a half of taking medication for hypothyroidism, your doctor will run tests to ensure that the medication is working as expected and make changes if necessary.

Hyperthyroidism treatment

If you're diagnosed with hyperthyroidism, your endocrinologist will likely prescribe a combination of medicine, radioactive iodine treatment, and/or surgery. Medications, including carbimazole and propylthiouracil can work to stop your thyroid from over-producing hormones. Some patients diagnosed with the condition also find that taking beta blockers can help to control their symptoms.

Radioactive iodine treatment uses radiotherapy to kill some of your thyroid cells. This can minimize the hormones produced by your thyroid, allowing your hormones to return to a healthy level. Some people also need surgery to remove some or all of the thyroid gland.
