Good sleeping habits are also an important part of healthful living. It is difficult for your body to grow and to fight off illness when you don't get enough sleep. Some studies show that heart disease and diabetes can be linked to lack of sleep.
It is also important to stay away from harmful substances, such as tobacco, alcohol, and drugs. Choosing to stay away from these things and choosing to make good hygiene, exercise, and good nutrition part of your everyday life will start you on your way to healthful living.
