There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need.
The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure.
How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas an expert（专家）in sleep. He says, “Sleep is like a credit card（信用卡）. When you sleep less. You are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to ‘pay back’ the hours on your ‘sleep credit card.’”
For those who value work more than sleep, they should listen to what a famous person once said. “Don’t think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more.”
