A good quality mattress is the first step. However, there are other steps that you can take to sleep well. Try to establish a bedtime routine that includes relaxing activities, such as prayer, reading or yoga exercises. Computer games and television can relax you as long as you observe a regular bedtime. Drink fluids before bed, but don't drink so heavily that you have to go to the bathroom in the night. Avoid alcohol. Don't exercise heavily before bed; otherwise adrenaline may keep you up. If you have to eat before bedtime, have something light. Foods high in tryptophan will also help you get to sleep. The major ones are warm milk, turkey, bananas, and peanut butter.
