A strong, healthy body can do an amazing job of resisting disease. There are many things you
can do to keep your body healthy. Eating proper foods is one of the effective ways. A balanced diet
gives the body the nutrients it needs to function properly.
Getting plenty of sleep is another good way. A tired, run-down body does not function
efficiently and is like a car that needs a tune-up. Sleep refreshes the body and restores the energy
necessary to fight disease.
Exercise is also important in reducing stress and keeping the body healthy. Regular, moderate
exercise, such as running, dancing, swimming, biking or playing a sport, will relieve muscle tension,
keep the muscles firm, and make the heart and blood vessels healthy. Exercise, like sleep, makes the
body function more efficiently. People who exercise regularly can even strengthen their hearts.
