Promoting Deep Sleep

Steps like these may also help restore sleep:

Eliminate alcohol and caffeine late in the day.
Keep the bedroom as dark and quiet as possible and maintain a temperature that is not too hot or cold. Use fans, heaters, blinds, earplugs, or sleep masks, as needed.
Talk with your partner about ways to minimize snoring or other sleep habits that may be affecting your sleep.
Exercise, but not too late in the day.
Try visualization and other relaxation techniques.
Try to unplug from the TV, laptop or your phone earlier.
