Getting enough hours doesn’t always mean the sleep you got was good. This category covers what shapes how restorative sleep actually is: mood, hormones, life stage, daily habits, and the tools people use to track it all.
Some of these factors are within your control (exercise timing, alcohol, tracking habits gone too far). Others are tied to a life stage you can’t change, like pregnancy or aging, but can still work with once you understand what’s happening.
