Evaluate Your Sleep Hygiene

Make sure your body is totally prepared for rest. You can't sleep if there is light in your room or if a TV is blaring in another room. Make sure your room is quiet, dark, and cool. Use earplugs if you are sensitive to noise, and wear an eye mask to block light. Eliminate afternoon caffeine from your diet, and exercise regularly -- although not near bedtime. Sometimes a snack that's high in carbohydrates can help induce sleep because it boosts levels of serotonin in your body. Serotonin is a chemical messenger that helps regulate mood, appetite, and sleep.
