It’s a shame current wearable devices aren’t great at assessing sleep problems, because we do need a solution that is less intrusive than all of the sticky sensors and loud monitoring required for a full PSG sleep test. That’s not useless information, but it’s far from the robust reporting that sleep trackers promise. The only information sleep trackers accurately gauge is how long you stayed in bed. As reported in Sensor in September, 2019, “results suggest that, to date, the available sleep trackers do not provide meaningful sleep analysis but may be interesting for simply tracking time in bed.” It turns out, fitness bands and watches aren’t great at measuring these qualities. How long did you sleep? Did you wake up again soon after you fell asleep? What was the quality of your sleep time? When scientists measure your sleep, they measure a number of different stages and events. Theoretically, the Apple Watch could also use its heart rate monitor, and even microphones, as part of a multisensor array, but Apple is not providing specific details about the feature beyond motion-detection.

They instead rely on accelerometers, and feed the motion data through machine learning software to guess what sort of sleep accompanied each movement, or each short “epoch” of time. Clinicians attach sensors to measure your heart (ECG), your brain (EEG), your eye movement (EOG), and skeletal-muscular activity (EMG).įor the most part, wearables don’t pack these sensors. When doctors measure sleep, they rely on a set of techniques together known as “polysomnography” (PSG). As the open access journal Sensor reported, “the currently available consumer devices for sleep tracking do not provide reliable information about one’s sleep.” Your wearable device doesn’t do a great job of tracking your sleep and giving you an accurate report in the morning.
Sleep tracking simply doesn’t work well, and you shouldn’t bother using your wearable device to track your sleep.
If you’re running motion sensors all night long instead of charging, that leads to an obvious question: When will you charge the device?Įven if you ignore the battery issue, there’s a more fundamental problem. OURA RingĪmid these developments, we have concerns about the effect sleep-tracking features will have on battery life. Oura makes sleep tracking a key feature of the device, and it’s the first feature you’ll see on the company homepage. The new Oura Ring is also getting a ton of press, thanks to a coronavirus-inspired partnership with NBA players. While it’s surprising that Apple never pushed hard for sleep features before, there may be a good reason for the delay.
