11.Do: Hydrate
You want to drink enough fluids so that you don’t wake up thirsty in the middle of the night, but not so much that you wake up because you need to pee. And of course, avoid alcohol and caffeine close to bedtime.
12.Do: Chill Out for Bedtime
Start to relax as bedtime approaches: no bright lights or stressful talks or activities. All of that can make it hard to fall asleep. Try to keep your bedroom dark and quiet. And cool, too: 60-67 F is ideal.
