For insomnia, you can try several methods. First, maintain a regular sleep schedule. Go to bed and wake up at the same time every day. Create a comfortable sleeping environment, keep it dark, quiet and cool. Avoid caffeine and heavy meals close to bedtime. Relax before sleep through activities like reading or taking a warm bath. Do some light exercise during the day but not too close to bedtime. If these don't work, consult a doctor. They may recommend therapy or medications. Cognitive behavioral therapy for insomnia can be effective. Don't stay in bed awake for a long time. Get up and do something relaxing until you feel sleepy again.
