The 7 Best Sleep Trackers of 2023, According to Doctors





These sleep devices are key to waking up feeling rested. Have you ever woken up feeling tired after a night's sleep? A one-time occurrence may be nothing to worry about, but if it happens regularly, your sleep health may be affected. 

Since you're unconscious while you sleep, it can be difficult to know what's going on. A sleep tracker can help you (and your doctor) pinpoint the problem so you can get the best rest possible, as quickly as possible. 

Sleep trackers are typically (but not always) wearable devices that record a variety of data, including heart rate, breathing rate, sleep onset and duration, sleep stage insights, and sleep position, although some devices provide more or less Function. 

In addition to identifying potential issues, these devices can "set and track sleep goals, provide personalized insights, and motivate you to improve your sleep," says Raj Dasgupta, MD. 

Dasgupta warns, however, that these devices are not completely foolproof, and they in no way preclude a visit to a sleep specialist if problems such as sleep apnea arise. "Sleep trackers are not as accurate as medical sleep studies," he explains. 

Although sleep trackers come in many different styles, there are some important things to remember when purchasing one. “A good sleep tracker should be comfortable, have long battery life, have an easy-to-use app, and be within your budget,” says Chisom Ikeji, MD, critical care physician and NatureMade health ambassador. 

Dasgupta adds that the best sleep tracker for you depends on your personal needs and preferences. "If you're not sure which features are important to you, talk to your doctor or sleep specialist," he advises. 

How we chose the best sleep trackers. With the help of our experts, we've picked out the best sleep trackers you can buy right now. Read on to learn more and shop for a good night's sleep. 

Overall the best - FitBit HR inspired: This iteration of the FitBit is an improvement over the previous model and offers more insight into sleep stages. 

"The FitBit Inspire HR has consistently performed well in clinical trials, and its technology has improved the performance of sleep tracking algorithms over the years," says Ikeji. The device automatically records and estimates your time in light, deep, and REM sleep. 

Ikeji also noted that the battery life is very good and the price is reasonable. It may not be the least invasive option on this list, as it requires wearing the wristband to sleep, but it's relatively lightweight and worth considering for its price and various other fitness features, like tracking calories burned during exercise and daily steps Number, worth the sacrifice. 

Basically correct - Hula 4.0: WHOOP 4.0 may look like just another simple wrist tracker, but it's much more than that. This screen-less, lightweight band is designed to fit seamlessly into your daily life and provide you with ultra-precise health data via five LED and four photodiode sensors. 

It can be worn 24/7 and is therefore waterproof. When it's time to charge, you don't have to take it off and lose your data. Instead, you can connect the brand's wireless, waterproof battery pack to power it on the go. 

Particularly when it comes to sleep tracking, users appreciate the ability to suggest optimal wake and sleep times, as well as the tactile alarm feature that gently vibrates to wake you up during optimal sleep stages. 

(Once you can read text on your wrist, it's hard to go back.) The technology's sleep-tracking capabilities are just an added bonus—and it actually works. The latest version tracks your body temperature, blood oxygen, heart rate, and sleep stages, and even breaks down how much time you spend in each stage: rapid eye movement (REM), core sleep, and deep sleep. 

The only drawback: If you want to use it as a sleep tracker, you have to find time to charge it, and not overnight. 

Best for beginners - Garmin Vivosmart 4: If you're new to sleep tracking, Dasgupta recommends trying a wrist-worn device because it "tracks total sleep time relatively accurately." The Garmin Vivosmart has great reviews and is fairly basic, making it easy to use. 

It measures blood oxygen levels, sleep stages and total sleep time during sleep and displays it in easy-to-understand graphs on the connected mobile app each morning. 

Best ring - Oura Ring: Ikeji also recommends the Oura Heritage Ring. Unlike many wristbands that use a less accurate green light, it uses NTC skin sensor technology and infrared light (commonly used in heart rate trackers in hospitals) to provide highly accurate measurements of your health stat sensors. Some people may also find it easier to wear it while sleeping than a bracelet. 

"Studies show it achieves results comparable to invasive sleep monitoring devices.
It's also stylish and can double as a fitness tracking device," Ikeji said. "I prefer this ring because I find it more convenient than a wrist device that I can wear in bed."


Best for light sleepers
Bía Smart Sleeping Mask
Anyone who is a light sleeper or wants to wear no accessories on their arms at night may appreciate this wearable sleep-tracking eye mask that simultaneously blocks light and takes your sleep habits into account.

“This is great for people like me who work all night and need to sleep during the day, or who are sensitive to light that affects sleep quality,” Ikeji said. "Sensors in the mask can provide neurofeedback, so it can theoretically detect sleep stages better." It also has an app that's easy to navigate, and it's Bluetooth compatible so you can stream music. The music will automatically turn off when it detects that you are sleeping. 

The best sleep tracking apps
sleep score
If you're not ready to invest in new technology, start with a sleep tracking app like SleepScore. Using your smartphone's microphone and speaker capabilities, your sleep stages, breathing rate, and body movements are recorded and a "sleep score" is displayed to you each morning. Upgrading to a premium subscription provides additional benefits, such as the ability to chat with a certified sleep coach, log your sleep trends, and weekly sleep insights.
