One in every five young people has sleep problems, so you are not alone. Getting enough sleep has become as important as eating vegetables and exercising regularly. ____1____.
Most young people only get seven hours of sleep each night, but they actually need nine hours. And making up for lost sleep during the week by sleeping on weekends doesn’t really work. In fact, sleeping late on weekends may actually do you more harm than good if you have sleep problems.
What happens if you don’t get enough sleep? If your sleep problem continues for a few nights, you could suffer more serious problems. ____2___. Worse, if your sleep difficulties last a long time, it could make you anxious or lead to depression.
___3___. Here are some suggestions:
Go to bed at the same time—including weekend, if possible.
Wake up the same time every morning. When you sleep late just one morning during the week, it may disturb your body clock. This will make it hard for you to sleep that night.
Do something relaxing before going to bed.
Exercise during the day. ____4____.
Avoid drinking alcohol. Alcohol makes you excited. This keeps you from falling asleep or wakes you up during the night.
Don’t smoke. ____5___. Smoking before bedtime keeps you awake.
If you trying the advice over a few weeks does not help you, speak to your doctor. Do not take any sleeping medicine without first asking your doctor. It may be harmful to health.

B. Don’t exercise right before going to bed.
