Use light strategically
Get bright light in the morning; dim lights and screens in the evening.
Reduce sleep disruptors
Limit caffeine later in the day and avoid heavy meals or alcohol close to bedtime.
Build a wind-down
Use a short routine (reading, stretching, shower) to cue sleep; keep the bedroom cool and dark.
