Healthy sleeping habits known as sleep hygiene can help you shift from daytime frenzy to nighttime slumber.
Go to sleep when you are tired and avoid caffeine four to six hours before bedtime. Don't smoke near bedtime, and finish dinner several hours before going to sleep. Keep your bedroom quiet, dark, and cool, and only use it for sleeping and sex.
And don't drink too much water. If you do, you'll wake up because you'll need to use the bathroom.
