5. Turn off late-night news
Given the fact that most late-night newscasts tend to feature murder, mayhem, and man’s inhumanity to man, these are bound to turn on every arousal mechanism your body owns. No way are you going to drift into a peaceful sleep after 30 to 60 minutes of watching violence and disturbing stories. So ditch the late news. Watch it in the morning when that shot of adrenalin it triggers will help you fight rush-hour traffic.
