Do you forget to log your migraine symptoms? 

Introducing Smart Reminders, powered by an AI system designed to detect your recent migraines. This feature not only supports you in tracking your symptoms but also invites you to play an active role in shaping the future of migraine detection. 

By responding to timely alerts and keeping your daily logs up to date, you help us learn and adapt to your unique patterns, paving the way for more personalized and accurate insights.

Regular tracking also helps you keep track of your migraines and possible triggers. You can use this to help prevent future migraines, or share the information with your medical provider to help with treatment options.

How it works

The Smart Reminders feature looks at data from your daily symptom logs, demographic information in your profile (like age and gender), and data from your connected wearable devices (such as steps, sleep, and heart rate) to determine if you might have experienced symptoms. 

This data is used to help identify patterns of a recent or on-going migraine. 

Once we detect a possible migraine, we deliver personalized alerts and follow-ups to remind you to log your symptoms. This way, you don’t have to remember to write everything down when you do have a migraine. 

We’ll share this data with you in your monthly reports (found in the My Health tab). That way you’ll have what you and your medical team need to better manage your symptoms and treatment.

Key features

• Timely Alerts: If you forget to log your symptoms on a day we detect patterns in your data consistent with a migraine, the Smart Reminders will nudge you to make sure your records stay complete and consistent for your next checkup.

• Post-Migraine Check-Ins: If you forget to log, we’ll follow up after a detected or reported migraine to track your recovery and see if you’re still experiencing symptoms.

Empowering personalized healthcare

Your participation is key to making Smart Reminders as effective as possible. By wearing your device consistently—both during the day and at night—and responding to symptom logs and alerts, you provide valuable data that helps us understand your patterns better. Over time, this collaboration leads to more personalized and accurate predictions tailored to you.

At Evidation, we’re always looking for innovative ways to empower our members. Smart Reminders is more than just a tool—it’s a partnership. Together, we’re building a smarter, more responsive way to manage migraines and support your health journey.

Healthy habits score overview

We’re excited to introduce a major new feature coming to the Evidation App: the healthy habits score. The healthy habits score has been designed by Evidation’s data scientists to estimate your current level of cardiovascular and metabolic fitness based on data from the wearable devices you have connected to the Evidation App. You’ll receive an updated score each week plus meaningful recommendations for how to improve your score based on what we see in your data. 

This new score will be available for some members starting early December. And we’ll continue to expand to all eligible members over the next few months. 

If you want to be one of the first to see this new healthy habits score, be sure to connect and use one of the devices listed below and grant permission for Evidation to have access to the required data. 

How it works 

The healthy habits score uses a variety of measurements commonly found on wearable devices to provide you with a numeric score between 1 and 100. Higher scores are generally better and are correlated with higher levels of cardiovascular and metabolic fitness. 

‍We calculate your score based on the following measurements and factors:

• Activity and Exercise: Daily average step count and daily average minutes spent exercising in specific heart rate zones
• Sleep: Average sleep duration during your “main” sleep period
• Physiological: Average resting heart rate
• Demographic: Age and gender. Note that this category is used only to put your other measurements in context. Measurements in the other categories vary in relation to age and gender, so it’s important that we control for these variables when building personalized recommendations on how to improve your score.

Frequently asked questions

How much data do I need in order to receive a score?

In order to send your score, we need both the right types of data, as well as sufficient data density (enough data to calculate your score accurately). Currently, our score only supports Fitbit, Apple Watch, Garmin, Withings, and Oura devices that capture heart rate, steps, sleep, and exercise. In order to calculate your score, we need 21 days of data out of each 28 day period to ensure an accurate score.

Note that the healthy habits score uses exercise as an input to calculate your score. Some devices auto log activities and exercise, while others require manual logging. In order to ensure you get the most accurate score possible, we recommend that if you have a device that does not auto log activities and exercise sessions, that you log these manually to ensure they’re accounted for within the Evidation app.

I’m a very active person and I received a low score, why?

Data that’s fetched from your wearable device provides only a partial view of your cardiovascular and metabolic health. Since the healthy habits score is meant to be an estimate of your general cardiovascular and metabolic fitness, we recommend focusing less on the current number and more on how you can improve your score over time. Also note that the healthy habits score is meant only for general health and wellness purposes and is not meant to treat or diagnose any health conditions.

How often will I get a healthy habits score?

You’ll see a new score in your My Health tab weekly, so be sure to check your app often. Please note that while the score updates weekly, the data used to calculate your score is from the 28 days prior. This means if you incorporate the recommendations given to you in any given week, you could see a lift in your score, but you won't see the full projected impact until you've incorporated the changes for the full 28 days. 

Health insights on Evidation

The Sleep Regularity Index (SRI) is a measure used in sleep research to gauge the consistency and regularity of a person’s sleep-wake schedule. It’s calculated based on factors such as bedtime, wake-up time, and sleep duration.

Researchers and healthcare professionals use the SRI to assess the quality and stability of an individual’s sleep-wake cycle. Irregular sleep patterns have been associated with various health issues, including mood disorders, impaired cognitive function, and cardiovascular diseases.

A higher SRI means that a person has more consistent or regular sleep patterns, while a lower SRI suggests more variability or irregularity.

Understanding your Sleep Regularity Index can help you make choices that improve your sleep schedule and overall well being. That’s why our team of data scientists went to work to deliver this valuable insight to our members.

How we calculate your sleep regularity index

SRI can be calculated in different ways. Evidation uses the probability that you are in the same state (awake or asleep) at any two times 24 hours apart.

To explain this, we have to get a bit technical. But hang in there, it’s worth it! 

To get the most accurate picture possible, we look at your sleep data to find the time you went to sleep and the time you woke up each day over a 30-day period.

We use that information to figure out the hours you were asleep or awake at the same time on 2 consecutive days (2 days in a row). The following chart is an example of sleep data over 7 days.  Each area from left to right represents 1 hour of 1 day. When the person was asleep, the area is filled in blue.

‍

For each hour of the day, we calculate how likely you are to be in the same state (awake or asleep) on consecutive days. We then average the values across all hours in the day to get your SRI.

As SRI is just a number, we provide a more detailed view of your sleep patterns through the daily sleep profile. The daily sleep profile is a plot of your likelihood to be asleep throughout the 24 hours of the day. The x axis (the horizontal line) is the time, and the y axis (the vertical line) is how likely you are to be asleep at that time.

‍

Very simply, the higher the bar, the higher your likelihood to be asleep. The lower the bar, the lower your likelihood to be asleep, in other words, the higher your likelihood to be awake. 

Middle-sized bars are for more “uncertain” times of the day when you’re neither very likely to be asleep nor very likely to be awake. It’s super important to be mindful of these times as this is when your sleep is the most inconsistent.

For many individuals, the daily sleep profile will look somewhat similar:

• it will be close or equal to 100% in the night time, between midnight and 6am, when they’re most likely sleeping 
• it will be close or equal to 0% in the day time, between 9am and 9pm, when they’re most likely awake, going about their day

The most interesting part is what happens between the high probability and low probability zones!

• people who are highly regular sleepers have more “all or nothing” profiles—at a certain hour they go from being awake 100% of the time to asleep 100% of the time 
• other people will have a pretty gradual decrease/increase in probability to be asleep: these are the more irregular sleepers   

It’s important to identify these “uncertain times” where your sleep is not regular. This is where you can work to move towards a more regular sleep schedule. Remember, going to bed and waking up at around the same time each day helps keep you healthy and well rested.

How do I interpret my Sleep Regularity Index?

The Sleep Regularity Index is defined as “the probability for an individual to be in the same state (awake or asleep) at any two times 24 hours apart”. So, if your Sleep Regularity Index is 92, it means that there’s a 92% chance that you’ll be awake or asleep at the same time each day.

Generally speaking, a Sleep Regularity Index in the 90s or above is considered good and healthy.

 How do I get my Sleep Regularity Index?

In order to receive a sleep regularity score from Evidation you must do the following:

1. Use a wearable device that logs sleep and connect it to your Evidation app. Make sure you enable sharing of sleep data when you connect your device.
2. Wear your device while sleeping for at least 20 of the last 30 days. We need to see your observed sleep in order to accurately calculate the Sleep Regularity Index. Too few data points will make our calculations inaccurate.

How often will I get my Sleep Regularity Index?

If you follow the steps above, we’ll send your Sleep Regularity Index to your My Health tab monthly. 

Remember to regularly sync your device with Evidation. This guarantees we’ll have the most accurate information for providing you insights like the Sleep Regularity Index.

Hypertension, commonly known as high blood pressure, is a significant health concern that affects over a billion globally. As a leading risk factor for heart disease and stroke, which are among the primary causes of death in the United States, understanding and managing high blood pressure is crucial for long-term health and well-being. 

High blood pressure develops over time and is often linked to a combination of genetic predisposition and lifestyle factors. It's called the "silent killer" because it can be asymptomatic for years, making awareness and early detection vital. Regular monitoring of blood pressure is essential for early intervention and management. The Centers for Disease Control and Prevention (CDC) provides comprehensive resources that define high blood pressure and its causes, and that emphasize the importance of measuring and monitoring blood pressure.

Interpreting your personal health data

At Evidation, we harness the power of personal health data to shed light on the modifiable factors (things you can change!) that may contribute to developing high blood pressure. By analyzing responses from your health surveys along with your wearable data – such as alcohol usage, smoking history, activities, and sleep patterns – we can identify key lifestyle patterns that may influence your blood pressure.

‍

The image above represents a range of health and lifestyle factors, and where you might fall compared to official guidance from the CDC and the American Heart Association (AHA) for managing high blood pressure or improving cardiovascular health. 

The blue bars stretching towards the right of the center line show where you are compared to the recommended range. These factors may have a positive influence on your blood pressure. For instance, if you sleep 9 hours per night on average, you’re well into the recommended range of more than 7 hours of sleep per night, which can help keep your blood pressure in a healthy range.

The red bars that don’t extend beyond the center line indicate areas for improvement. If, for example, your aerobic minutes are less than 150 minutes per week on average, the red bar suggests that a beneficial change would be to increase your physical activity, in particular your aerobic minutes (for example, by spending more time doing moderate exercises, like brisk walking, biking, or mowing the lawn). Increasing your physical activity may lead to an improvement in cardiovascular health and may improve hypertension prevention and management.

The path forward

Our goal at Evidation is to empower individuals with actionable insights. By understanding where you stand, you can take informed steps to maintain the positive behaviors and address the areas where change could lead to better health outcomes.

Monitoring personal health data is a proactive step towards understanding and mitigating the risks associated with hypertension. By focusing on modifiable lifestyle factors, we can work towards prevention and improved health. For more information on how to manage and prevent high blood pressure, visit the CDC's High Blood Pressure page.

Information is key when it comes to figuring out how you can take your physical health to the next level. At Evidation, our team is proud to offer you the tools necessary to track and analyze your health-related data, using your personal metrics to provide recommendations, information, and suggestions that allow you to make informed decisions that support your well-being.

Evidation's health monitoring capabilities

Using the Evidation app is simple—we're here to help you understand the health data you're already tracking, and reward you for actions that support your health.

We start by asking your permission to utilize the data you're already tracking through apps like Fitbit or Apple Health. Our app will then ask you questions to help us learn more about you and your goals, as well as offer surveys and articles tailored to your personal health needs. With your permission, we'll use your data both to provide you with information and suggested action steps that will support your health, as well connect you with opportunities to contribute to research that supports the development of modern medicine.

Key metrics for physical health optimization

In today's age of information overload, it can be tough to figure out what health information actually matters. At Evidation, we're here to provide you with the support that you need to make the most of your health data. Here, we'll take a look at the metrics that are most important for you to keep track of in order to optimize your health.

Role of activity tracking in health improvement

We all know that it's recommended that we get 10,000 steps a day, and using a step tracker is a great way to encourage yourself to increase your activity. At Evidation, our activity tracking allows you to see the ways that movement is improving your health.

New research shows that people who receive prompts to keep up with physical activity took an average of over 800 steps more than people who did not receive similar prompts.

Keeping track of your activity throughout the day and week can help you pinpoint the times when you're less active, which may make it easier to find ways to add more activity to your day, according to Harvard Health.

Sleep data for better physical health

Understanding your sleep data can provide you with the insight you need to get better rest. Most sleep trackers can tell you how much time you're spending in each stage of sleep, helping you to understand how your energy levels are affected by the time you spend asleep each night.

Tracking your sleep data can also provide your health care provider with valuable information in the event that you're experiencing difficulty sleeping. While sleep trackers don't take the place of a sleep study, they can work to help your doctor determine whether it's possible that you're experiencing abnormal sleep disturbances.

Sleep trackers can also help you to maintain good sleep hygiene, as you can get crystal-clear data on the time you go to bed each night and wake up each morning. This can help take away the temptation to put off going to bed or to scroll on your phone once you lie down.

Stress levels and their impact on well-being

Stress can affect all systems in your body, and understanding how your stress levels fluctuate can help you learn more about how to use stress management techniques to support your health.

Tracking your stress levels can help you see if your stress is related to particular situations, as well as whether your stress levels could become a health concern. Stress that isn't managed well can lead to several health issues, including heart disease, stroke, diabetes, and high blood pressure.

Nutrition tracking and its influence on physical health

Life is hectic, and it can be tough to stay on top of your daily nutrition habits. Simply tracking what you eat—even if you're not making any changes to your normal routine—can help you spot connections between your food and your health.

Nutrition tracking can also help you learn more about what foods help you feel your best. You may find that you have your best workouts after eating a complex carbohydrate-heavy meal, or you may find that eating a large amount of protein right before you go to sleep makes it harder for you to get a restful night’s sleep. Many people are surprised to find that tracking their nutrition makes it easier for them to understand other aspects of their health.

Mental wellness metrics for holistic health improvement

It can be easy to forget to check in with yourself throughout the day, but doing so is important in understanding how your habits and activities are affecting your mental health. Evidation regularly asks you simple questions about your mood and well-being. By taking a second or two to tap an answer, you'll be well on your way to learning more about how your activities—from exercise to sleep and everything in between—positively or negatively affect your mental health.

The information gathered from tracking your mood can help provide your mental health care provider with valuable insight into how you're coping with stress, as well as how different activities affect your well-being. You may find it helpful to pull up your mood tracker during therapy sessions, as this can provide you with clues as to how you and your care provider can work together to support your mental health.

Often it’s interesting to know how your body and behavior change over time. That’s why we’re introducing a new insights feature: week over week changes. Beginning next week, members will receive weekly insights when Evidation observes a significant change in your weekly step count or average resting heart rate.

How it works

If you connect a wearable device to Evidation and give us permission to analyze your data, we’ll analyze your daily steps and resting heart rate data each week to determine if there was a notable change between last week and the week prior. In this case a “notable” change means at least a 20% change in your average daily step count. For resting heart rate, notable means at least a 5 beat per minute change in your average daily resting heart rate.

How do I interpret my week over week changes?

How do I get my week over week change alerts

In order to receive week over week change insights you’ll need to do the following:

1. Use a wearable device that logs either steps or heart rate (or both!) and connect it to the Evidation app. Make sure you enable sharing of steps and heart rate data when you connect your device.

Learn more about pairing connected devices here. 

2. Wear your device at least 6 days per week. We need enough data on a weekly basis in order to accurately detect meaningful changes.

How often will I get my week over week change alerts?

You’ll receive weekly alerts if you wore your device enough during the week, have your device connected, and we detect a meaningful change. If you do not receive an insight and have your device connected, it means we didn’t find any significant changes in your steps or resting heart rate.

Here's to a healthier tomorrow with My Health on Evidation!

Evidation Members tell us they love seeing insights in the app such as how their sleep and mood are connected or how their mood or sleep impacts their activity levels. So we’re always working to provide new and valuable health insights for our members.

To that end, we’re kicking off an exciting new project… 8 new insight types in 8 weeks!

Here, we’ll dive into the first of these new insights — sleep debt! Keep an eye out for more insight types coming soon.

What is sleep debt?

At a high level, sleep debt is just a measure of how much you sleep compared to how much you ideally should sleep. 

‍There are two kinds of sleep debt: 

• long term sleep debt that you accumulate over months and years, and 
• short term sleep debt that you accrue over days and weeks. 

Both are important, but the measurement we provide members focuses on short term sleep debt — specifically sleep debt calculated over the last 14 days.

Learn more about sleep debt and the associated risks here. 

How Evidation tracks your sleep debt

Here’s the overview of how Evidation calculates sleep debt:

1. First we estimate your “ideal” nightly sleep duration based on sleep data logged on your sleep tracker. This number is personalized to you, but for almost everyone this number will be between 7 and 9 hours of sleep per night.
2. We then look at your actual sleep duration over the past 14 days. For each day, we take the difference between your ideal sleep and your actual sleep to calculate a daily sleep debt score.
3. The daily sleep debt scores are then adjusted to account for the fact that recent sleep debt is more impactful than sleep debt you accrued far in the past. For example, sleeping only 2 hours last night will make you feel terrible today if you’re used to consistently sleeping 8 hours each night, but if you had a night where you slept 2 hours a week ago, it would impact you far less today, assuming the other nights you slept your usual 8 hours. 
4. Finally, we take the adjusted daily sleep debt values and sum them up over the last two weeks. This is your total short term sleep debt.

How do I interpret my sleep debt score?

‍The graph you’ll see in the evidation app shows four different pieces of information:

1. Your daily sleep duration over the past week
2. Your ideal sleep duration (the dotted horizontal line)
3. Your daily sleep debt (the red bars that are stacked on top of your daily sleep duration on days you slept less than your ideal sleep duration)
4. Your total sleep debt calculated as discussed above (the final red bar)

How do I get my sleep debt score?

In order to receive a sleep debt score you must do the following:

1. Use a wearable device that logs sleep and connect it to the Evidation platform. Make sure you enable sharing of sleep data when you connect your device.
2. Wear your device while you sleep as often as possible. In order to receive your sleep debt score, we need at least 10 days of sleep data every two weeks. Too few data points will make our calculations inaccurate.

How often will I get my sleep debt score?

For now, you’ll see your sleep debt score weekly. In the future, we’ll begin updating your sleep score daily so you can better track your score over time. Knowing your sleep debt score makes it possible to take steps to improve your sleep and get the rest you need to feel your best.
