Ethan Weiss, a cardiologist at the University of California, San Francisco, has been wearing a ring on his finger called Oura Ring, which includes a sleep tracker, for nearly a year.

(Duh.) Buried deep inside the data was some general information about sleep, but the app stopped short of offering advice on how to solve my personal sleep problems.Дr. My sleep-tracking statistics said I needed more sleep. O.K., but what happens once you collect your sleep data from a tracker or an app? There is no real answer. He added that the devices enabled some sleep tracking to be done in the real world, not a lab. Michael Grandner, director of the University of ArizonaвЂ™s sleep research program, who has consulted for Fitbit, said that wrist-worn sleep trackers had a long history of use in scientific research and that some devices could be very accurate at measuring sleep stages. Some scientists said consumer-grade sleep trackers should not be dismissed as inaccurate. In contrast, the algorithms used by university sleep labs have been publicly shared for decades. David Walsh, the computer scientist who developed AutoSleep, said he knew the movement and heart rate sensors would not accurately estimate the REM stage, so he didnвЂ™t bother.ДЄnother unknown for sleep trackers are the algorithms that are being used to measure peopleвЂ™s sleep, Dr.

Here is where the AutoSleep app gets credit: It estimates sleep duration and deep sleep using the motion and heart rate sensors, but it does not attempt to guess REM sleep. In sleep-tracking labs, the gold-standard scientific equipment typically includes sensors that are connected to someoneвЂ™s face and neck to measure eye and brain activity, among other variables. ThatвЂ™s partly because the cycles are not the same throughout the night: The early cycles have more deep sleep, whereas the later ones have more REM sleep.Д«ut our sleep-tracking tech? It generally canвЂ™t accurately measure REM sleep. To get a good nightвЂ™s sleep, you need to complete four or five cycles. On average, a person completes a sleep cycle, which includes each of the three main stages, every 90 minutes.

REM sleep, the stage in which we dream, helps in repairing our psychological and emotional networks. The deep sleep stage is beneficial for physical restoration, like muscle reparation and metabolism recovery, researchers said. There are three main stages: Light sleep, deep sleep and REM sleep (for rapid eye movement). To understand sleep-tracking data, I delved into how sleep works. HereвЂ™s what I learned after two weeks of sleep tracking. вЂњYou may think: вЂOh, gosh, I didnвЂ™t sleep well. вЂњIf you look at your data, it can modify the perception of your sleep,вЂќ he said.
