And keep yourself occupied - boredom can also lead to insomnia. Reset your body's clock. If you fall asleep too early, use light to push back your internal clock. In the evenings, go outside in the sun or sit near a bright light. Avoid or limit naps.
Naps can make it harder to fall asleep at night.
If you can't get by without one, try to limit it to 45 minutes. A warm bath or light snack before bedtime may help prepare you for sleep. The harder you try, the more awake you'll become. Read or watch television until you become drowsy and fall asleep naturally. Check your medications.
