Frequently Asked Questions

I know you were looking for what are the best options, but here is some more detail as to why you would want to use a sleep tracking device you wear at night.

What are Sleep Trackers?

Sleep trackers are usually wearable devices that measure the quality of your sleep and track it within a connected smartphone app.

Sleep trackers are designed to give you an idea of how much quality sleep you are getting each night. They track deep sleep, light sleep and periods of wakefulness during the night.

Theoretically, you can use this information to make lifestyle changes that allow you to get more and better quality sleep.

While most sleep trackers stop there, some go a step further and provide you with personalized steps you can take towards achieving your sleep goals.

Many sleep trackers also feature a smart alarm that will wake you up while you are in a light sleep phase so that you are not woken out of a deep sleep.

How Does Sleep Tracking Work?

Sleep trackers use accelerometers to measure the speed and directions of your movements while you sleep. The software analyzes these movements and determines periods of sleep and wakefulness. This is called actigraphy. While actigraphy can be an accurate way to track sleep, it tends to have a high margin of error because it is only tracking motion, not brain waves or eye movements. (ref)

Also, rather than tracking all five stages of sleep, it simplifies sleep into “light” and “deep”. So while sleep wearables can be accurate, they only offer a rough estimate of sleep quality. (ref)

Types of Sleep Tracker Devices Available

Here is a list of the types of sleep wearables out there.

Sleep trackers have gotten more competitive over the last few years, with many different types becoming available.

Many companies are now making sleep and activity trackers that look like jewelry, so that you can track your metrics in style.

When to Use Sleep Tracking Wearables to Help Improve Sleep?

There are numerous situations in which tracking your sleep may be helpful.

Most of us don’t get enough high quality sleep every night, so simply being aware of what your sleep patterns are can help you be more conscientious of your sleep habits. Here are some examples of situations in which sleep tracking can help.

It’s also important to mention when not to rely on sleep tracking wearables to help improve sleep.

If you have a sleep disorder, it is best to go to a health professional who can track your sleep using scientific instruments that can measure brain waves and eye movements, as these are much more accurate ways to assess sleep quality.

Sleep Tracker Device vs Sleep Tracking App

Here are the benefits to using a wearable sleep tracking device versus just an app on your iPhone or Android phone to measure sleep quantity and quality.

A sleep tracking app can be a great way to keep track of how much you sleep each night, but if it is not connected to a wearable sleep tracking device, it is probably not telling you anything you don’t already know.

Plus, can you be trusted to input your own sleep information accurately, even if you’re a little disappointed in yourself for not quite hitting that all-important eight-hour threshold?

Is It Safe to Wear Wearables When Sleeping?

Side effects from sleep wearables are miniscule. While there has been some concern about wearable devices emitting small amounts of radiation, the consensus in the scientific community is that the level of radiation is negligible.

For comparison, a cell phone emits 100 times more radiation than a wearable, and cell phones are considered generally safe.

As far as physical side effects go, you might experience some irritation from a wearable wristband or headband.

Inevitably, some people will use the information from these devices for medical or health purposes. This is not recommended.

Sleep wearables are safe for people with normal sleep patterns, but they may not be accurate enough for those with sleep disorders. That’s why it is important that you talk to your doctor first and, of course, choose a wearable that is reliable. Wearables that do not work as intended can unintentionally put users at risk.


Are Sleep Trackers Accurate?

Wearable sleep tracker devices are more accurate than sleep tracker apps. However, both wearable devices and smartphone apps are not as accurate as polysomnography, which is the gold standard for measuring sleep in a clinical setting.

The following sleep trackers have been tested in scientific research papers for accuracy compared against polysomnography.
