How to do it

  1. Pick a wake time you can keep every day, then count back at least 7 hours for your bedtime.
  2. Keep weekend times within about an hour of your weekday times.
  3. Keep the bedroom quiet, dark, relaxing and cool.
  4. Get outside in daylight during the day, and stay active.
  5. If you nap, keep it to 20 minutes or less and take it earlier in the afternoon.

Why it helps

Your body clock runs on routine. Regular sleep and wake times make it easier to fall asleep and wake up rested. Most adults need 7 or more hours a night. Shift work, late screens and catching up on weekends all push the clock around.

Be careful

If you snore loudly, stop breathing in your sleep, or still feel exhausted after enough hours in bed, talk to a doctor. Shift workers who can't adjust should also ask about other options.
