During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for 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 body relaxes (放松) little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts (变换) back and forth from one level of sleep to the other. Though your mind slows down, you will dream from time to time. Scientists who study sleep point out 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 (建议) breathing very slowly and very deeply.

Dr. Waltor Powys, formerly with the United States Air Force, noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate (硫酸盐) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body.
