How The Apple Watch Tracks Sleep

FitBit sleep prediction: scientific test (full year)!

It’s rare that Apple lags far behind other brands, but Apple didn’t have its own sleep app until recently: you had to use a third-party app, such as Pillow.;

As of watchOS 7, however, you can track your sleep through Apple’s built-in Sleep app. Watch OS 7 works with the Apple Watch Series 3, 4 and 5, as well as the new Apple Watch Series 6 and Apple Watch SE. If you own one of the earlier versions, make sure your OS is updated. WatchOS 7 isn’t compatible with the Series 1 or 2, though.;

Once you’ve set up sleep-tracking on your Apple Watch, the Sleep app can detect when and how you’re sleeping, based on your movement and your heart rate. You can use it to set sleep schedules and goals and request a wakeup alarm. You can also set a wind-down time, meaning the watch will go into Sleep Mode for a period in advance of you going to sleep.;

To our own surprise, we weren’t hugely impressed by the Apple Sleep app. It’s crammed with information, but, aside from the heart rate information, not much of it is all that useful. We’ve tried many other watches that are easier to use for sleep-tracking while also providing for information. You won’t get information on sleep phases either although, as we explained, such data shouldn’t be taken too literally anyway.

If you were using Pillow before, you can continue to do so, if you prefer.;

What Are Fitness Trackers

Fitness or activity trackers are wearable smart gadgets that are typically fashioned as bracelets. Similar to pedometers, these devices count the steps you take every day. But they can also measure other data points such as your heart rate, weight loss, distance traveled and sleep patterns. Fitness trackers then sync up to your smartphone via Bluetooth, giving you access to all this information via their associated app.

While they often share features with smart watches, activity trackers stand apart in the amount of fitness-focused data they collect. Smart watches often have a few activity-focused features, but fitness trackers typically collect more in-depth information.

Types Of Sleep Trackers

While sleep trackers come with a wide variety of designs and features, they can typically be classified into one of two categories: wearable and non-wearable. We dive into the different varieties of wearable and non-wearable sleep trackers below:

Wearable Sleep Trackers

As noted above, wearable devices typically also serve as fitness trackers. Wearable devices are most commonly worn around the wrist as wristwatches or wristbands, but may also be worn as rings and other accessories on the body.

Non Wearable Sleep Trackers

Also called no-contact sleep trackers, non-wearable trackers are placed under mattresses, on bedding, or built into the actual mattress itself rather than worn on the body. You may prefer a non-wearable sleep tracker if you tend to find wearable technology obtrusive.

How Do Fitness Trackers Track Sleep The Science Behind It All

Image from

For a few decades we have marveled at the ability of our fitness trackers to record and analyze our every move. They cheer us on when we reach our fitness goals and remind us when we need to get moving. Recently these small devices have done even more to improve our health. They now tell us how we are sleeping. When you wake up in the morning, you can now check the app that is tied to your fitness tracker to see how well you slept. So the question is, how do fitness trackers track sleep? Read on to find out.

Heart Rate And Respiration

Some sleep trackers estimate REM sleep in addition to deep and light sleep stages by measuring heart rate. Although heart rate and respiration rates are known to vary greatly during sleep, they have a close relationship with each sleep stage since the autonomic nervous system significantly affects both. Respiration is considered the most important parameter of physiological data because it clearly indicates sleep disorders such as snoring and sleep apnea according to research published in the journal,;Sensors.

Well break down some of the top things to look for when purchasing a sleep tracker. While all of these factors matter to a certain extent, some may not be high priorities for you. Assessing what you want in a tracker can help you hone in on the most important aspects.

Sleep Tracking: Sleep trackers capture an array of data that may include heart rate, heart rate variability, respiration, snoring, time awake, time sleeping, sleep interruptions, and body temperature. Some may also monitor room temperature, humidity, noise level, and light. Since trackers vary in what sleep-related factors they detect, shoppers should pay attention to the specific product details to find an option that collects the information that interests them most.

Sleep Analytics: Sleep analytics use the data from sleep tracking to delve more deeply into sleep quality and patterns. They may provide detailed charts to show you how your sleep has changed over time, overlay multiple sets of data to show you how different factors are linked, and provide you with a daily sleep score. Wearable trackers can also link your daily activity levels to the quality and duration of your sleep.

Other Features: Sleep trackers often come with additional features, like fitness tracking, GPS, coaching, and integrations with other apps. These components may make your device more versatile, insightful, or convenient, but they can also increase the price-point.

Many people use sleep trackers because they are not sleeping well. They are hopeful that they may learn a little bit about why they are having difficulty sleeping. If insomnia persists, this search can become desperate. Although some insight may be gleaned, more evaluation may be necessary. If you have poor sleep, especially if you have trouble sleeping through the night with frequent awakenings or experience daytime sleepiness, get evaluated by a board-certified sleep physician to sort out what might be contributing to your troubles. Wearables may identify a problem, but they cannot typically provide the solution.

The Withings ScanWatch is the most detailed and accurate sleep tracker weve used. On top of recording your sleep duration, depth, regularity, and interruptions, it uses its medical-grade SpO2 monitor to detect breathing disturbances overnight. Breathing disturbances are detected when the ScanWatch performs a Respiratory Scan, which measures your heart rate,;heart rate variability, respiratory rate, and oxygen saturation levels.

One downside to the ScanWatchs sleep tracking is that it does not monitor your REM sleep stage. Withings said its keeping that functionality exclusive to its sleep mat .

  • Small display limits smart features
  • Few advanced fitness features or insights

Add In The Algorithms

CNET News – How accurately do fitness trackers monitor sleep?

As you might already know, its difficult to get two fitness trackers to agree on how much activity youve got through in a day or what your heart rate actually is. Thats because the sensors inside each device arent perfect at measuring what youre doing they all use slightly different algorithms to translate the raw data into actual statistics.

Read this: How Fitbit is hoping to crack sleep apnea

For example, your tracker might dismiss a small movement of the wrist and not include it as a step. But how small is too small? Different devices will have different thresholds and thus bring back different readings. Anything from a bumpy car ride to a plush carpet can throw off the accuracy of your fitness tracker.

When it comes to calories, an app needs more than just a step count to make the calculation: thats why youll often be asked for your age, gender, height and weight too. The algorithms used by each manufacturer arent made publicly available, as each one likes to keep a lid on the secret sauce they use to get the best and most accurate results, but the more sensors and data points used the more accurate the results are likely to be.

To really tell how many calories youre burning, for example, a tracker needs to add data about your heart rate and how much youre perspiring into the algorithm alongside how many steps youre taking.

Will Tracking Make You Anxious

There is one caveat: If you tend to be anxious, tracking your sleep may not be helpful, cautions Dr. Lance.

Some people can become obsessed with their device, checking their data constantly and worrying about whether its normal to awaken during the night.

But we all awaken at night, she says. The question is, do we fall back asleep OK, and can we function OK the next day?

Wanting to track your biometric data, however, is generally a good thing, Dr. Lance believes. It means youre more likely to follow doctors orders and do what it takes to maximize your well-being.

Consumer sleep technologies offer a wonderful, relatively inexpensive way to become more engaged in your overall health, she says.

Eight Sleeps data processing also raises more privacy concerns than some of the other trackers featured in this article. According to a representative, the product is managed via Wi-Fi and app connection, and transmits data on your sleep to a warehouse for analysis.
