Step 4: Regularity Regularity of bedtimes and getting up times helps ensure good sleep. If possible, try and go to bed and wake up at the same time every day. Keep your bedroom dark while you are sleeping so that the light will not interfere with your rest. As soon as it's time to wake up, open the curtains or turn a light on. Light helps your body know it's time to wake up. Planned daytime naps are fine, but naps caused by sleepiness will ruin your night-time sleep. Try to stay awake all day if you can.
