Avoid bright light at least 30 minutes before going to bed—including that from the TV or computer. Light governs your internal clock and suppresses melatonin, a hormone that makes you feel tired. The absence of light stimulates production of this hormone, so you feel sleepier.

Try a pre-bed snack that includes tryptophan, an amino acid that causes sleepiness, and carbohydrates. Examples include a small bowl of oatmeal with milk, half a turkey sandwich on whole grain bread, or a 6-ounce banana smoothie made with milk.

Develop a ritual to break the connection between sleep and the stress of the day. A few to try: Make a list of any pressing issues and a possible plan for dealing with them, or simply look at favorite photos that relax and calm you.
