You might want to be living a healthy lifestyle. Before you go charging
of, though, you should understand how important safety is. For
example, exercising isn't going to do you much good if you hurt yourself
doing it, is it. Probably not. You can follow some simple safety
rules so you won't get hurt. Whether you're exercising, riding in
a car, or just hanging out, you can help prevent accidents and injuries.
You can be safe and still have fun. When you play a game or sport, follow it's rules. Don't be rough. Wear the right clothes, shoes, and protective equipment, like helmets and pads.
Always be careful when you are crossing the street. Watch for traffic. Before you cross make sure no traffic is coming.
You can avoid falling by wiping up spills at once. Don't leave anything lying around where somebody could step on it or trip over it. Always ask yourself, "What is the safe thing to do?" Then do it.
the Nutrients You Need"
"Avoiding Tobacco, Alcohol, and Other Drugs"
are chemicals that change the way the body works. Medicines are drugs
that are used to prevent, cure, and treat illnesses. If used carefully,
medicines can be helpful to health. Other drugs do
in your healthy lifestyle.
Cigarettes and other tobacco products contain a drug called nicotine. It makes your heart beat faster than normal. It narrows the blood vessels so less blood flows through them. Nicotine also causes dependence, which is the need for a drug. People who use tobacco often find it extremely hard to quit.
Tobacco smoke also contains carbon monoxide a poisonous gas that replaces some oxygen in the blood. Tar is another substance found in tobacco smoke. Tar builds up in a smoker's lungs where it can cause cancer cells to grow. Substances in tobacco smoke can also cause emphysema and contribute to atherosclerosis.
Alcohol found in beer, wine, and liquor, is another drug to stay away from. Alcohol slows down the work of the brain, changing the what a person acts, thinks, and feels. After many drinks, a person may have trouble making decisions or remembering things. Muscles may not work together properly. A person's vision may be blurred. Someone who drinks and then tries to drive a car is more likely to have an accident.
Drinking a lot of alcohol over a long period of time can cause brain damage, liver disease, and cancer of the stomach and other organs. Alcohol can also cause dependence. Alcoholism is an illness in which a person is dependent on alcohol and cannot control his or her drinking.
Drug abuse is the intentional use of drugs for reasons other than health. Some people abuse alcohol. Others abuse marijuana, cocaine, or heroin. Those drugs are illegal. They can harm health. They can cause dependence. The only drugs you should take are medicines from a doctor. If anyone else offers you any other drug, say "no".
"Getting Enough Rest and Exercise"
Getting enough rest and exercise is another
important part of a healthy lifestyle. Resting after working or playing
helps tired muscles recover. Rest also can help relieve stress.
Sleep is a special kind of rest. During sleep your breathing, heartbeat,
and some other body processes slow down. Then more energy is available
to build or repair body cells. You should get 9 or 10 hours of sleep
Regular exercise benefits your body in many ways. For example, exercise can help you keep a healthy body weight. Exercise helps keep arteries clear of fatty substances. Exercise makes muscles flexible. Exercise also strengthens muscles, including the heart muscle, diaphragm, and muscles between the ribs.
A stronger heart muscle can pump more blood with beat. A stronger diaphragm and rib muscles make it possible for your chest cavity to expand more as you inhale. That means you can take in more air with each breath. The result is that your body cells get the oxygen they need with less effort by your heart and lungs.
Sports like soccer and basketball are good for your whole body, including your heart and lungs. But you don't have to play sports to be healthy.
You don't have to do exercises that you think are boring. Riding a bike, skating, jogging, swimming, and jumping rope are all good exercises. Walking, dancing, and skiing are also good for you. Try to do some vigorous activity every day.
Before you exercise, warm up. Get your muscles ready for vigorous activity by doing slow, gentle stretches or by walking or jogging slowly for a few minutes. After you exercise, cool down the same way. That will loosen up tight muscles and help to prevent soreness.
