Sleep is not optional: small changes that actually help

Sleep advice tends to arrive as a long list of rules, which is precisely why most of it doesn't stick. A shorter, more honest version: consistency matters more than duration, light matters more than most people expect, and the last hour before bed does more damage than the rest of the day combined.

Going to bed and waking up at roughly the same time — even on weekends — does more for how rested you feel than chasing an extra hour of sleep on an irregular schedule. Your body adjusts to rhythm faster than it adjusts to willpower.

Bright light in the evening, especially from screens held close to the face, delays the body's natural signal to wind down. It doesn't have to mean no screens at all — just dimmer, and ideally not the last thing before you close your eyes.

If poor sleep has been a pattern for weeks rather than days, or comes with snoring, gasping, or daytime exhaustion that rest doesn't fix, that's worth raising with a doctor rather than another sleep app — it can be a sign of something a night routine won't solve on its own.
