If you are having trouble falling asleep， you are in good company. About 65% of Americans said they have sleeping problems a few nights each week， according to a recent study by the National Sleep Foundation. Sleeping too little can lead to a higher risk of becoming fat and getting depressed （沮丧的 ）. But before you go to a doctor for advice， it is worth examining your sleeping habits one more time. Some of your favorite evening habits may have something to do with the sleeping problems.

1. Setting a Bright Alarm Clock

The light of your bright alarm clock can prevent you from falling asleep. You can make your room as dark as possible. Cover the bright numbers with a book or consider buying a small travel clock. Your cellphone alarm may also do the trick.

2. Counting Sheep

When you just cant fall asleep， its useless to stay in bed to count sheep. If youve been trying to fall asleep for more than 30 minutes， the National Sleep Foundation suggests you get up to do some reading or watch TV for a while. Such activities will make you sleepy. Before you know it， youll be going back to bed really tired.

3. Exercising Late at Night

Daytime exercises will keep you full of energy for hours. Thats why you dont want to exercise within three hours of hitting the sack. Fierce （剧烈的 ） physical activities raise your body temperature and improve your energy level—both are bad for a good nights sleep.
