Put aside any work, touchy discussions, or complicated decisions 2 to 3 hours before bed. It takes time to turn off the "noise" of the day. If you’ve still got a lot on your mind, jot it down and let go for the night. Then, about an hour before you hit the sack, read something calming, meditate, listen to quiet music, or take a warm bath.
Tip: Even 10 minutes of relaxation makes a difference.
