How smart watches detect deep sleep?
The sleep tracker, like most on the market, measured heart rate and movement . The idea is that because, for example, the heart slows as you move into stage 2 (deep sleep) of our four-stage sleep cycles, and the body is paralysed during REM sleep, the tracker can estimate the stage you are in.

An average sleep cycle lasts about 90 minutes. Ideally, you need four to six cycles of sleep every 24 hours to feel fresh and rested. Each cycle contains four individual stages: three that form non-rapid eye movement (NREM) sleep and one rapid eye movement (REM) sleep .

How do fitness trackers track sleep?
