Two things: 1. Too much deep sleep might not be desirable. 2. Sleep staging by activity trackers is generally pretty inaccurate. Garmin is no exception.

- fasteo 1y agoCould you please elaborate on 1. ?
- elric 1y agoDifferent processes happen during different sleep stages. Typically people go from light sleep to deeper sleep stages (slow wave), to REM in a cyclical pattern. We go through each of the stages roughly every 90 minutes of "quality sleep". There's usually more deep sleep at the start of the night, and more REM towards the end of the night. If you end up with too much deep sleep (e.g. after being very physically exhausted for a while), you will have little or no REM sleep and your sleep quality will suffer. It's not just "too much deep sleep" that could fuck things up, being woken up multiple times can also mess up your sleep cycle, whether it's by crying children or sleep apnea.
- tartoran 1y agoPersonally, I am very alert throughout the day if I sleep between 6-7 hours. Past the 7 hours threshold I am get into a worse headspace (brainfog) throughout the day proportionally to the amount of extera sleep.
