Cold plunge benefits & alternatives
Cold plunging is all over social media. Here, we'll dive into the truth behind cold plunge benefits, as well as alternatives you can try.

Cold plunging—the practice of immersing yourself in an icy bath in hopes of mental and physical health benefits—has gone viral on social media. If you're shivering at the thought of plunging into a tub full of ice water first thing in the morning, but are curious as to the health benefits, we're right there with you. Here, we'll explore everything you need to know about cold plunging, including potential benefits, the pros and cons of jumping into an icy tub, and alternatives to cold plunging.
What is a cold plunge?
Also known as cold water immersion, cold plunging involves submerging your body (usually, up to the neck) in super-cold water (between 39°F and 59°F) for up to 10 minutes. A cold plunge can be completed in an outdoor cold plunge tub prepared with ice and cold water, a converted chest freezer, or an icy natural body of water (such as a lake or ocean). Beginners may prefer to give cold plunging a try in their home shower or bathtub at first, where the temperature can be more easily adjusted, and they aren't subject to the outdoor elements.
Why is cold plunging so popular?
While cold plunging has experienced a hyper-increase in popularity recently due to social media, it's rooted in ancient tradition. Cultures in Egypt, Greece, Russia, Japan, and Scandinavia have used cold plunging as a part of health routines and rituals for thousands of years. Today's cold plunge practices typically work to meld mental and physical health benefits.
Many hugely successful athletes, including LeBron James, swear by cold plunging for physical recovery and mental clarity. Some biohackers—social media personalities who produce content on how to make the most of your health and well-being by making changes to daily routines—say that cold plunging offers metabolic and immune health benefits. Others say that the endorphin rush and resilience-building power that comes with stepping outside of your comfort zone can set you up for success throughout the rest of your day.
Many believe that cold plunging pairs well with cold weather workouts, such as trail running in the winter, cross-country skiing, or participating in outdoor boot camps. After pushing through a tough workout in the elements, a quick dip in a cold plunge tub can feel exhilarating before warming up indoors.
Benefits of cold plunging
Cold plunge benefits differ from one person to another. The research on cold plunging is ongoing, and many of the benefits of cold plunging are anecdotal. If you're interested in giving cold plunging a try, be sure to take note of the benefits you experience, and don't force yourself to keep up the routine if it's not the right fit for you.
Some of the reported benefits of regular cold plunging include:
- Reduced muscle soreness: Regular cold plunges may help to reduce inflammation and numb nerve endings, which can make it easier for you to bounce back after tough workouts.
- Increased circulation: Moving between exposure to cold and exposure to warmth can create an extra workout for your cardiovascular system that can strengthen blood vessels and improve circulation.
- Enhanced mental resilience: Doing something difficult first thing in the morning can help create a sense of mental fortitude for the rest of the day. For some people, this can help to manage anxiety, discomfort, and difficult emotions later in the day.
Cold plunge pros and cons
There's no doubt about it—cold plunging can be an effective way to wake up and get your mind right for the day.
Some of the pros of cold plunging include:
- Quick energy and mood boost. The feeling of exhilaration you get from a cold plunge can create a positive tone for the rest of the day.
- Improved muscle recovery. Lowered inflammation and increased circulation can decrease soreness, reduce the likelihood of injury, and improve muscle recovery after workouts.
- Increased mental toughness throughout the day. If you've already completed your toughest task of the day before you head to work, you may find that it's easier to overcome other challenges.
- Easily accessible for beginners: As we mentioned, a cold shower or cold bathtub can be a good start for cold plunging, making it easily accessible to anyone who wants to give it a try.
- Can be done at home or in nature: Since cold plunging is versatile, you can complete it outdoors or indoors, at home or in a hotel room, etc.
Some of the cons of cold plunging can include:
- Discomfort, especially as you get used to the process. For many, the thought of spending time in cold water brings feelings of anxiety and discomfort. If you find that cold plunging causes you high levels of stress, it may not be worth the potential physical and mental health benefits.
- Health risks: Cold plunging may not be a safe choice for those with heart conditions, high blood pressure, or other health conditions. Cold plunging can affect the heart's rhythm, so it may not be a good fit for those concerned with cardiac health issues.
- Risk of hypothermia. If you decide to give cold plunging a try, start slow, spending just 30 seconds in the cold plunge tub until you understand how your body reacts to such a vast temperature change.
As with any new health routine, it's a good idea to talk with your doctor before you give cold plunging a try, especially if you have heart conditions or other health issues that may be negatively affected by temperature change.
Cold plunge alternatives
If you'd like the benefit of cold plunging but don't love the idea of diving into a tub of ice first thing in the morning, you aren't alone. Thankfully, there are some other options you can use to improve your mood, boost mental clarity, and start your day off right.
- Contrast showers: Alternating between hot and cold water in the shower can increase circulation and provide you with a manageable version of exposure to the cold. Over time, you can try to increase the amount of time you spend in cold water.
- Cryotherapy: Cryotherapy is a high-tech alternative to cold plunging that exposes the body to super-cold air for two to three minutes at a time. Cryotherapy chambers are super-expensive, with a used model costing tens of thousands of dollars. Many people who are interested in cryotherapy purchase sessions at a wellness center, where they can enjoy the benefits without such a massive investment.
- Outdoor winter walks: If you live in an area with cold winters, spending time in the brisk air can energize your body, enhance your mood, and help to build your tolerance to the cold. It can take some time to get used to the cold. You may want to start with spending just a few minutes walking outdoors before coming inside to warm up with some yoga, Pilates, or other gentle movement.
- Breathwork and meditation: Practicing breath control techniques (especially paired with mild cold exposure) can provide similar mental clarity and stress resilience benefits. Using a simple meditation app a few times a day can help you get into a routine.
- Sauna or heat therapy: While it seems counterintuitive, spending time in a sauna or using other types of heat therapy can offer similar benefits to cold plunging, as heat can increase circulation, reduce inflammation, and improve mood.

Men’s Health Matters — During International Men’s Health Week and Beyond
International Men’s Health Week is celebrated every year the week before Father’s Day. The focus of the event is on men’s health, wellness, and prevention — which is critical to lowering risk factors for disease.
Men’s Health Matters — During International Men’s Health Week and Beyond
International Men’s Health Week is celebrated every year the week before Father’s Day. The focus of the event is on men’s health, wellness, and prevention — which is critical to lowering risk factors for disease.
Statistically, men tend to avoid routine medical care and avoid seeking medical care until much later than other genders.
A 2019 survey from the Cleveland Clinic’s MENtion it campaign highlights some of these statistics.
Why?
According to the Cleveland Clinic Survey, stereotypes and social conditioning surrounding gender play a large part.
“Why do men avoid the doctor? Stereotypes taught at a young age may be to blame. Two-fifths (41%) of men were told as children that men don’t complain about health issues.”
International Men’s Health week is an opportunity to focus on the specific health concerns men face, and a way to say, “Hey, guys, your health is important!”
It’s a great time to schedule events, have informed conversations, and raise awareness around men’s health and wellness.
But, the importance of men’s health doesn’t stop at the end of the week. It’s critical that we continue to focus on men’s health throughout the year and remind the men in our lives that they matter and that their health matters!
Regardless of gender, we can all play a part in helping men to feel confident seeking health care!
Luckily, today more than ever, there are many resources focused on the issue of men’s health! We’ve included a short list of resources below. And we encourage all men, everywhere, to remember that their health matters!

Honoring Juneteenth
We celebrate the connection between identity and whole person health. In this spirit, we honor Juneteenth (short for “June 19th”) which marks the end of slavery in the United States.
Honoring Juneteenth
At Evidation, we celebrate the connection between identity and whole person health. In this spirit, we honor Juneteenth (short for “June 19th”) which marks the end of slavery in the United States.
What is Juneteenth
While Abraham Lincoln issued the Emancipation Proclamation on January 1st, 1863, only a tiny number of people were actually freed at that point.
In Texas, the last enslaved African Americans were declared free two and a half years after the Emancipation Proclamation and two long months after the fall of the city of Richmond.
Juneteenth, which commemorates the anniversary of that historical event, June 19th, 1865, has been observed and celebrated ever since.
Juneteenth is not just a pivotal landmark in American history for many Black Americans, but a representation of independence, freedom, and hope. A moment in time where the road to equality seemed more visible than it had ever been. Some of the most impactful pioneers in the history of civil rights were born from the breath of life that June 19th generated.
History of Juneteenth Celebrations
Juneteenth festivals could be observed extending from one state to another as formerly enslaved individuals relocated throughout the country.
Juneteenth celebrations commonly included singing, dancing, and coming together over food and fellowship.
Some of the first sightings of Black fashion have been connected to Juneteenth celebrations as clothing was a vital part of these festivities.
One way for formerly enslaved people to celebrate their emancipation was by wearing bright and vivid attire that they were unable to wear while enslaved. There are significant connections between those early festivities and modern-day Juneteenth gatherings that exist today.
Juneteenth Inspires
While we celebrate Juneteenth this weekend, let’s use this as an opportunity to remember that the fight for equality and liberty for Black Americans is not yet finished. Many injustices persist, and we must reflect on their impact on health and identity.
Today we fight to bridge the gap to access essential resources, education, healthcare, and equal opportunities, and representation that one day will be celebrated in ways that Juneteenth has paved the way for.

Are you a Morning Lark or a Night Owl?
Discover your sleep type plus 5 tips for better sleep.
Some of us naturally go to bed early and wake up early feeling refreshed and ready for the day. Others feel best when they are up late and wake later in the day.
And while much of the way our work life and society is structured seems to favor the early risers, the tendency toward one pattern or the other is entirely normal, natural, and individual.
Whether we are more inclined to be morning larks or night owls is based on our biology!
Our circadian rhythms to be exact.
According to the National Institutes of Health,
“Circadian rhythms direct a wide variety of functions from daily fluctuations in wakefulness to body temperature, metabolism, and the release of hormones. They control your timing of sleep and cause you to be sleepy at night and your tendency to wake in the morning without an alarm. Your body’s biological clock, which is based on a roughly 24-hour day, controls most circadian rhythms. Circadian rhythms synchronize with environmental cues (light, temperature) about the actual time of day, but they continue even in the absence of cues.”
Scientists call this tendency toward thriving in the morning or at night our chronotype.
Your chronotype score is determined by looking at your mid-sleep time (the exact midway point between when you fall asleep and when you wake up) and adjusting based on differences in your sleep habits between your free days and non-free days.
You can learn more about chronotypes and how our genes affect this aspect of our lives with this master class preview from Professor of Neuroscience, Matthew Walker.
Where do Evidation Members Fall?
Thanks to wearable health devices and sleep tracking apps, we’re now able to really see what our sleep patterns and chronotypes are.
Turns out many of our current members are morning larks!
How did we determine this?
We compared sleep data on non-free (work/school) days to sleep data on free days.
Why?
Because social obligations like work and school can interfere with our natural preference for morning or night.
So, in order to know where we truly fall, we need to look at how we behave when we have the freedom to follow our natural habits.
Specifically, we looked at when individuals fell asleep, when they woke up, and their mid-sleep times.
On average, the members whose sleep data we looked at, had mid-sleep times of around 2:50 am.
But to determine chronotype score, we need to look at the difference in total hours slept between free days and non-free days because people often sleep more on free days.
On non-free days, the average mid-sleep time was 2:35am. And on free days, it was 3:21am.
This tells us that while people did tend to go to bed later (and sleep in a little later) on their free days, it wasn’t much later.
So, how do we determine whether someone is a morning lark or a night owl?
We compare their chronotype score to the average (median) chronotype score of other Achievers.
What we found is that many of the members we looked at tended to be early risers.
This graph represents the distribution of recorded mid-sleep times (chronotypes).

Tips for Better Sleep
Whatever your chronotype, there are things you can do to help improve the quality of your sleep — and good sleep is important for so many reasons!
According to the Division of Sleep Medicine at Harvard Medical School,
“sleep plays a critical role in immune function, metabolism, memory, learning, and other vital functions.”
That means that how you sleep directly affects your health, your mood, your weight, your ability to function and work or school, even the success of your interpersonal relationships.
And it’s one of those areas where quality is even more important than quantity.
Here’s our top 5 tips for getting better sleep!
- Unplug. Step away from your electronics for a good hour or more before going to bed. We know it’s hard to resist the pre-bedtime scroll — so much of our lives are connected to our devices! But it will help you sleep better.
- Maintain a regular sleep schedule! This one is critical. While our circadian rhythms are largely determined by biology, environment plays a HUGE role as well. Irregular sleep schedules interfere with our natural rhythms and can make it difficult for us to sleep.
- Get regular exercise. Even a small amount of exercise helps our bodies maintain balance, and that’s great for healthy sleep. Just be sure to exercise at least several hours before you plan to go to bed. Exercise gets our endorphins going and can keep you awake if too close to bedtime.
- Manage any anxieties or tasks before bed. This is especially important if you’re one of those individuals who lies in bed thinking about all the things you need to do. Make a list before bed and then set it aside until the next day.
- Create a restful space for yourself. Usually that means a space that is organized or free of clutter, dark, cool, and quiet. White noise like a fan can help for some.

Why is Mental Health Self Care So Important?
Studies show that mental health is just as important as physical health. And little things like taking time for self care can make a huge impact. check out these tips for working mental health into your daily routine.
Why is Mental Health Self Care So Important?
The importance of mental health self care
We all know the importance of taking care of our bodies. When we neglect them, we become ill. Eating right, getting adequate rest and exercise, managing any chronic conditions — these are critical to maintaining good physical health.
But what about mental health?
Studies show that mental health is just as important as physical health. And little things like taking time for self care can make a huge impact.
So why do so many of us neglect this aspect of our wellbeing?
We asked Achievement users how often they made time for mental health self care, what types of activities they typically did, and what keeps them from practicing self care as often as they’d like.
What did we learn? That while many of our users do practice regular self care, the majority of them don’t do it as often as they’d like.
Why?
The most common responses (in order) were:
- Not enough time
- Pressures of daily life
- Financial burdens
We also discovered that while many of those who responded said that self care was very important to them (almost 75%), and almost 70% said they would like to practice self care daily, only 27% do.
So, in honor of Mental Health Awareness Month, we’d like to share some quick, easy, free ways to practice regular mental health self care!
10 tips for working mental health self care into your daily routine
- Take a quick (5–10 minute) walk or bike ride
- Download a free meditation app — most have practices as quick as 1–2 minutes!
- Look in the mirror and tell yourself one thing you like about yourself
- Reach out to someone who helps you feel good about yourself
- Sing your favorite song
- Draw or color something
- Go to bed 10 minutes earlier than usual
- Close your eyes and focus on your breath for 1 minute
- Hug someone
- Write down 5 things you are grateful for
These are just examples of some of the ways you can practice mental health self care daily. We encourage you to find ways that work for YOU!

Honoring ALL Who’ve Fallen this Memorial Day
For many of us, memorial day is the unofficial start of summer. It’s the day the neighborhood pool opens. The day the parks, beaches, and amusement areas start filling up. The day the BBQs, picnics, and beach parties begin. But while we enjoy these freedoms, we should also take the time to remember why we honor memorial day in the first place.
The True Meaning of Memorial Day
For many of us, memorial day is the unofficial start of summer. It’s the day the neighborhood pool opens. The day the parks, beaches, and amusement areas start filling up. The day the BBQs, picnics, and beach parties begin.
And it’s good that we enjoy these things. After all, it’s for these things that our service members fight.
But while we enjoy these freedoms, we should also take the time to remember why we honor memorial day in the first place.
History.com defines Memorial Day as,
“an American holiday, observed on the last Monday of May, honoring the men and women who died while serving in the U.S. military.”
Unlike Veteran’s Day, which honors all of our service members, Memorial Day is special in that it is a day of remembrance.
And for our veterans and for the families and loved-ones of fallen service members, Memorial Day is often a day of honor and pain. A day of remembering. A day of visiting graves and paying tribute to fallen friends and loved-ones.
History of Memorial Day
Memorial Day (formally Decoration Day) was declared a national holiday in 1971 but has been observed since the end of the American Civil War.
And while the tradition of visiting the graves of fallen soldiers began sometime during the civil war, the first recognized formal observance was held in May 1868 and annually after that.
The first recorded observance, however, actually occurred three years earlier, just after the end of the war. It was held by freed slaves in Charleston, South Carolina in honor of fallen union soldiers.
If you’re interested in learning more, this post from History.com is an excellent resource.
Memorial Day, Mental Health, and Veteran Suicide
While memorial day traditionally focuses on those who’ve given their lives while in active duty, it’s important that we not lose sight of those who’ve given all in service, whether their sacrifice occurred during active duty or after their service has ended.
Rates of mental health problems and suicide among vets and active duty service members are staggering and and have increased in recent years. Many sources indicate a rate of around 20 suicides per day.
According to an article by Militarytimes on the latest report on veteran suicide rates,
“The rate of suicide among veterans ticked upwards in recent years despite increased public attention and funding on the problem.”
It’s important to note that while this report was released in November 2020, the numbers reflect rates from 2015–2018. Data suggests that these rates have continued to increase and have escalated even more during the Covid-19 pandemic.
So, since May is also Mental Health Awareness Month, we’d like to take this opportunity to pay tribute to those who’ve lost their lives in service to this country — both on the battlefield and at home — and we’d like to remember those who are still with us but struggling.
Thank you. And thank you to the families of those we’ve lost. Your sacrifice is not forgotten.

Creamy Asparagus Soup
This rich, creamy asparagus soup is one of those go-to comfort meals. It will easily satisfy your want for flavor, and the best part…it’s super healthy. So you get all of the glut with none of the guilt!
This rich, creamy asparagus soup is one of those go-to comfort meals. It will easily satisfy your want for flavor, and the best part…it’s super healthy. So you get all of the glut with none of the guilt!
It’s naturally gluten free, vegetarian, and keto — and with one simple swap it can be vegan and paleo too!
Food is such an integral part of our daily lives, and while we know that eating healthy is important to our overall well being, it can sometimes seem difficult to find delicious meals that are good for you.
So we’ve decided to create a place to share these gems.
This is just the first of many healthy, tasty recipes we’ll be sharing with our Achievement community. Each of these recipes will come from Achievement team members or Achievement users like you!
We’ll also tell you a little about the recipe author and the dish. Because sharing a meal is about so much more than the food. It’s about coming together.
The Story
I love asparagus! And it just so happens, that May is National Asparagus Month! And since it’s also Celiac Awareness Month, I knew I had to share this recipe.
I’m a sucker for cream soups, but I have celiac disease which can make it almost impossible for me to find safe soup in a restaurant or out of a package. Most cream soups start with a roux to ensure that rich, creamy texture.
Now, I could get that with a gluten-free flour, but I try to keep things as simple and healthy as possible.
So creating a thick creamy soup without the need for thickeners was top priority for me!
Luckily, I love to cook.
This soup gets it’s texture by using the parts of the asparagus stalk that you would normally toss out. Which also means it helps reduce food waste — which is a big win!
And the best part…it’s full of good-for-you nutrients and easily aligns with many dietary needs and preferences.
Ingredients:
2 pounds fresh asparagus
1 small onion
2 cloves garlic
4 cups vegetable broth (or chicken broth)
1 cup heavy cream
Pinch of fresh ground nutmeg (pre ground will work too!)
Salt and pepper to taste
Directions:
- Trim woody ends of asparagus and place in a large pot — reserve the rest for later! ***If there are very thick, hard parts at the bottom, remove and discard.
- Cover with broth and heat to boiling.
- When the broth reaches a full boil, reduce to simmer, cover, and cook until stalks are tender. 20–40 minutes, depending on the toughness of the asparagus stalks.
- Remove any stalks that have remained too hard or woody (that won’t puree nicely).
- Chop onion and garlic and remaining asparagus. Add to the pot. These can be rough chopped as it will all be pureed later.
- Return to a boil. Add a pinch of salt and a pinch of freshly ground nutmeg. ***You can leave the nutmeg out if you don’t like it or are unsure. The idea is not to taste it, just to add a depth of flavor to the soup.
- Cook until veggies are tender.
- Remove from heat and puree using an immersion blender, or allow to cool and transfer to a standing blender in batches and then return to the pan.
- Reheat until warmed through and add in cream. Allow to heat through, but do not boil.
- Salt and pepper to taste.
Modifications:
This dish is already gluten free, vegetarian, and keto-friendly (trust me, you won’t know it — it’s so rich and delicious!). But you can easily make it Vegan and Paleo as well by substituting the heavy cream with full-fat coconut cream.
If you’re not familiar with coconut cream, it’s the solid part of a can of coconut milk (before you mix it up). So, if you can’t find canned coconut cream, you can use the solid cream part of a can of coconut milk.
It does change the flavor a bit, but I’ve done it plenty of times and it is still very tasty!
Tips:
- I save the woody ends of asparagus throughout the year and freeze them. Then, when I want to make this soup, I pull them out of the freezer and cook them down with the rest. This gives the soup a much deeper flavor. And it means less food waste!
- Use chicken bone broth instead of vegetable broth for added nutrition and a dose of gut-healing collagen!

The Women who Inspire our Evidation Members
Meet the women who inspire us to be our best selves! In honor on National Women's month, take some time to honor the inspiring women in your life.
Last month was Women’s History Month and later this month we celebrate one special group of women in our lives — the group of women we call mothers.
We know that Mother’s Day can be difficult for many, and we recognize that the word “mother” means many things.
With that in mind, we want to share the love and inspiration that comes from the women in our lives, whoever they are.
Some of these women have given birth, some have raised us, taught us, picked us up when we’ve been knocked down. Others have been friends, sisters, aunts, lovers. Some, we have lost.
But each of them have inspired us in one way or another.
And inspiration is something we appreciate here at Evidation.
So, we’d like to highlight the women who’ve inspired our community of members!
We recently asked Evidation Members about the women who inspire them, and the response was amazing!
Over 19,000 members sent us inspiring stories of the women in their lives.
It took us a while to get through the many heartfelt submissions, and while we’d love to share them all, we’ve chosen to highlight a few here in honor of women everywhere.
Meet our members and the women who inspire them

“Ms. Thomas was my first African American female teacher in the third grade; also my only till I reached college. We instantly bonded and have a relationship to this day. She was such a smart and powerful woman and I think she is one of the many people that have encouraged and supported me to become the woman I am today. I could not imagine what my school experience would have been without her. She was always there to offer me extra support outside of class time and continued to help when I was no longer in her class. I can say that I love this woman and am so glad that she is a part of my life.” — Brieanna, Lexington

“My friend Michelle inspires me in many ways. She is a retired firefighter/paramedic. She has been a competitive bodybuilder. Is a yoga instructor, painter, quilter and end of life doula. When she turned 50 she walked the Camino de Santiago and hiked the Kalalau in Kauai, both in a skirt. (Because, you know, year of the skirt). She is a wife, mother, and grandmother. She loves life and encourages others to love themselves and their life too.” — Karen, Las Vegas

“My Lola (grandmother in Tagalog) is a truly inspiring woman. She originally graduated at the top of her class in accounting, then when she was in her 40s, she fought ageism and attended medical school to become an ophthalmologist. Not only is she brilliant, she is also a wonderful mother to 7 children, and Lola to her 13 grandchildren and 2 great grandchildren. She was also one of the first female drivers in the Philippines. While my mom’s classmates were being picked up by their drivers, my Lola decided to learn how to drive a car so she could pick up her children herself. At 94 years old today, she is still brilliant, witty and going strong.” — Mariella, Toledo

“Nhu is a very dear friend of mine and she came to USA around 1980. She became USA citizens and is very much a good person. She has had her struggles along the way as she lives here in the USA and had always been a positive person no matter what happened to her as far as people treat her, she has always look to a more positive attitude towards them as she goes on with her life, she appreciate being here from where she came from she is a refugee from Vietnam and I can only imagine what her life was before her life here! To be so patient and positive about things takes a lot of patience and I love and dearly respect her for that. She has inspired me to look at things in a more patient and kind away in my life. She is a very dear and precious friend to have.” — Sher, Tacoma

“She has been my head principal for 10 years, and she continually inspires teachers, students, staff, parents, and the community to do and be their best. She never accepts excuses, and is continually looking for solutions to problems that make our high school awesome. She also treats everyone equally, which I never experienced until she came. She even helped our band to get funding for new marching band uniforms which we haven’t had in a few decades. I’m just sad to see her retire at the end of this school year, but wish her the best in her next chapter. I’m very grateful for knowing because she has made me a better teacher. I’ll never forget her.” — Charles, West Jordan

Preliminary Results from our Second COVID-19 Vaccination Perceptions and Behaviors Survey
COVID-19 vaccines have been a source of hope and trepidation for many. We wanted to know how individuals felt about the vaccines
The release of COVID-19 vaccinations has been a symbol of hope to many people — -and a source of hesitancy to some. For our second survey on COVID-19 vaccination perceptions and behaviors (which we will refer to as “survey 2” throughout this blog post), we wanted to understand how people were feeling about the vaccines as people first started getting access to them. We launched the survey in January 2021, and are excited to share some preliminary results with you!
Participants
100,080 people (“participants”) completed survey 2. 54,701 have completed all surveys in the study so far. The mean age of survey 2 participants was 37.4 (standard deviation: 12.2 years). The majority of survey 2 participants identified as female (80.8%) and identified as white (78.0%).
.jpeg)
Vaccination Likelihood and Hesitancy
One of our main focuses for this survey was to examine how COVID-19 vaccination likelihood and hesitancy has evolved over time.
11.4% of participants had already gotten a COVID-19 vaccine when they took the survey, with an additional 0.6% reporting participating in COVID-19 vaccination trials:
.jpeg)
Overall, survey 2 participants reported being more positive about COVID-19 vaccination than they had been previously. 30% of participants reported feeling more likely to get a COVID-19 vaccine than they had been a month ago:
.jpeg)
People reported a range of reasons for their likelihood of vaccination increasing, with some common responses including:
- Feeling more informed about COVID vaccination overall (for example, “learned more information about it”, “just thinking and researching”)
- Feeling more confident about COVID vaccination safety as more data and research were released (for example, “more data on potential side effects”, “studies are getting better and more people are receiving it.”)
- Feeling more confident about COVID vaccination safety as they saw their friends, family, and community starting to get vaccinated (for example, “seeing those I respect get it”, “watching people I know get it with little adverse side effects”)
We saw a similar trend looking at the differences between reported vaccination likelihood in the first and second surveys; mean reported likelihood was 4.93 in survey 1 (median=5), and 6.53 in survey 2 (median=8.0):

Although the majority of participants (51.5%) still report being more hesitant about COVID-19 vaccines than other vaccines, a higher percentage of survey 2 participants reported being equally or less hesitant than survey 1 participants:

Vaccination Informedness
As mentioned above, one common reason people gave for their increase in vaccination likelihood was feeling more informed about the vaccines. Our data reflect this increase in self-reported informedness; in survey 1, only 27.1% of participants reported feeling “informed” or “very informed”, but 53.3% did so in survey 2:

The most common pieces of information unvaccinated participants reported needing to know before deciding to get the COVID-19 vaccine were all potential side effects (62.7%) and possible long-term impacts of vaccination (58.9%).
We look forward to further investigating these current perceptions and behaviors and see how they change as more people become eligible for vaccination!
Next Steps
To understand how people’s perceptions and behaviors related to COVID-19 vaccination continue to evolve as vaccines become available more broadly, we will send additional surveys over the following months asking for Evidation Members’ perceptions and behaviors. The exact dates of these future surveys will depend on developments in the pandemic and COVID-19 vaccination, so stay tuned for more!

How Election Night 2020 Impacted Our Bedtimes
Do people stay up later on election night? Find out what we discovered.
Our Research, Analytics, and Learning team is exploring and analyzing data from our Evidation platform, where members contribute to research and help us uncover insights that could improve their health and the health of others.
During this year’s presidential election there was high voter turnout which included record-breaking numbers of mail-in ballots due to COVID-19. As we now know, this high volume of ballots required multiple days to count, so no final winner could be projected on Election Day. We decided to look at Evidation Members activity data to see what changes the election may have caused for our members.
We used Fitbit data contributed by Evidation Members, to explore sleep characteristics and schedules for the month leading up to Election Day in 2020. We looked specifically at the time that each member went to bed in their local timezone. Equivalent time periods in 2017–2019 were used for comparison. These periods were aligned across years based on week rather than calendar date, so that differences in weekend and weekday sleep cycles would line up. This also syncs the end of daylight saving time, which happened on November 1, 2020, the Sunday two days before Election Day, and temporarily shifts our sleep cycles earlier. Positioning the data in this way allows for appropriate comparisons of data across years.
So, did anything about our sleep change? This plot shows the average time Evidation Members started sleeping on the weeks leading up to and immediately after daylight saving time from 2017–2020:

There is a clear weekly pattern: we go to bed later on Friday and Saturday nights, when we have a weekend day ahead of us. On daylight savings weekend we started sleeping slightly earlier as we adjusted to the end of daylight saving time, a trend which continues through the following week as we slowly adjust to going to bed later again. However, on Election Day 2020 this pattern was disrupted; bedtimes spiked up over 20 minutes from Sunday and Monday night.
You may also notice the interesting pattern of later bedtimes in 2017, leading up to daylight saving time. This lines up with Halloween night and games 6 and 7 of the 2017 World Series. We’ve examined the impact of the 2017 World Series on sleep in the past.
As we looked closer at our sleep data, we were curious to see if members on the East Coast stayed up later in their time zone than those on the West Coast while they waited for results, so we examined average bedtimes in each time zone. On election night, members on the East Coast stayed up the latest (11:51 PM), compared to members in the Central (11:39 PM), Mountain (11:39 PM), and Pacific (11:43 PM) time zones. Compared to the previous night, members in Eastern Standard Time stayed up 22 minutes later, Central Standard Time 20 minutes later, and Mountain Standard Time 23 minutes later, while members in Pacific Standard Time stayed up only 14 minutes later.

Regardless of where we live, sleep is an important part of our health. Fortunately, later bedtimes due to the election were confined to Tuesday night. Bedtimes returned to normal after Election Day, as it became clear that election results would take at least several more days to be projected.
