A relaxing evening helps you fall asleep. Avoid stressors like email and tough talks with family members at least an hour before bed. To get in the mood for slumber, you can meditate, stretch, take a warm shower or bath, or read a book in a low-lit room. If you get at least 7 hours a night but you're still worn out, see the doctor. A health problem or a sleep disorder like sleep apnea may be to blame.
