3. After a busy day of work and play, the body needs to rest. Sleep
is necessary for good health. During this time, the body recovers from the
activities of the previous day. The rest that you get while sleeping
enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the
one before. As you sleep, your muscles relax little by little. Your heart
beats more slowly, and your brain slows down. After you reach the fourth
level, your body shifts back and forth from one level of sleep to the
other.
Although your mind slows down, from time to time you will dream.
Scientists who study sleep state that when dreaming occurs, your eyeballs
begin to move more quickly (although your eyelids are closed). This stage
of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing
very slowly and very deeply. Other people believe that drinking warm milk
will help make you drowsy. There is also an old suggestion that counting
sheep will put you to sleep!
