Dogs sleep, cats sleep and you sleep. All mammals and birds sleep. Elephants sleep only 2 to 4 hours a day. Bats sleep 18 hours a day. Children need more sleep than grownups. A newborn baby sleeps 17 to 18 hours. A 10-year-old needs about 10 hours of sleep a night. Grownups need between 6 and 9 hours of sleep a night.
Though scientists do not know for sure why you sleep, they do have some ideas. Safety could be one reason for sleep. People and other animals might sleep because it keeps them safe at night. Sleep might also help you work better. Things go wrong if you do not get enough sleep. It is hard to think and work and play unless you get plenty of sleep. Besides, sleep is necessary for good health.
Scientists have learned a lot about what happens when you lie down, close your eyes, and fall asleep. Sometimes your eyeballs move back and forth while you’re asleep. They move fast. This kind of sleep is called REM, which means rapid eye movement. Your brain is also very busy during REM sleep. It is almost as busy as when you are awake. What do you think your brain is doing? Here is a clue: You dream during REM sleep.
If you have trouble falling asleep, some people suggest breathing very slowly and very deeply. Other people believe that drinking warm milk will help you make you drowsy. There is also an old suggestion that counting sheep put you to sleep!
