Plain-English sleep tips
- Keep a steady schedule. Going to bed and waking up at the same time every day trains your body clock.
- Dim screens before bed. Try to avoid bright phone and laptop screens for 30 minutes before sleep.
- Skip late caffeine. Coffee and strong tea in the afternoon can keep you awake at night.
- Cool, dark and quiet. A dark, quiet bedroom a little on the cool side helps most people sleep better.
- Wind down, do not scroll. A short calm routine — like reading or a warm shower — beats doom-scrolling in bed.
