Your body clock runs on cues, and a few of them are easy to adjust.

Morning light

Daylight early in the day helps set the clock so you feel sleepy at a sensible time.

A steady schedule

Going to bed and waking at similar times — even on weekends — makes falling asleep easier.

A cool, dark room

A slightly cool bedroom and less screen light in the last hour both help. General information only.
