American Academy of Sleep Medicine
Make your bedroom quiet and relaxing. Keep the room at a comfortable, cool temperature (60 to 67° F /15 to 19° C)
Limit exposure to bright light in the evenings. Consider red, yellow, and orange lights.
Turn off ALL electronic devices (yes, including the TV) at least 30 minutes before bedtime.
Avoid eating large meals 2-3 hours before bedtime. If you are hungry at night, eat a light (less than 200 calories), healthy snack (ex: tart cherries, bananas with almond butter, kiwi, protein smoothie).
Exercise regularly & maintain a healthy diet.
Avoid consuming caffeine in the afternoon or evening.
Avoid consuming alcohol before bedtime.
Reduce your fluid intake 1-2 hours before bedtime to avoid waking up to use the bathroom & disrupting sleep.
Try to keep a consistent sleep schedule. Get up at the same time every day, even on weekends or during vacations.
Set a bedtime that is early enough for you to get at least 7-8 hours of sleep.
Don't go to bed unless you are sleepy. This helps train your brain to associate your bed with rest.
If you don't fall asleep after 20 minutes, get out of bed. Go do a quiet activity without a lot of light exposure (ex: mindful stretching/yoga)
Establish a relaxing bedtime routine.
Use your bed only for sleep & sex.
