Teenagers don't often appreciate being told what to do. They believe themselves nearly adults and expect to be treated accordingly. Some of them live like they plan to exist forever, feeling invincible. The problem is that many teens are still suspended between childhood and maturity, with much to learn about good health and accident prevention strategies.

As a concerned parent, you may feel helpless as you watch your son or daughter grow to adulthood. But while theyre still in their teens and under your roof, you can follow a few simple steps to provide your teenager with the best possible health protection and common sense advice that a parent can offer:

1. Serve nutritious meals. Though many teens eat on the run, they always enjoy home cooked meals. Often they'll brag about Mom's cooking or Dad's barbecue to their friends. Take advantage of their appreciation to offer a balanced diet full of fruits and vegetables. Check the American Heart Association's dietary guidelines for a healthy and nutritious eating plan. Get rid of fattening snacks like cake, cookies, or candy. Opt instead for fresh fruit, cheese, and nuts, and your teen will likely get used to the switch in a hurry.

2. Consider offering vitamin supplements. Ask your doctor if a vitamin is advisable for your teen. It probably won't hurt, and actually may help to make up for lost nutrients due to fast food meals and crash weight loss programs. Have your teen checked by a doctor at least once a year to be sure his weight and height are where they should be.

3. Encourage enough sleep. Eight to nine hours is good for a teen whose body is still maturing. Some teens even take naps after school, which helps their bodies to grow in a healthy way. Provide a clean bed and quiet hours at night when your teen can get his or her quota of sleep. Don't let him go out every night or lead a hectic life. Recommend times of rest and reflection between the busier periods, accompanied by activities like listening to soothing music and writing in a personal journal.

4. Support physical activity. School or community sports, family hiking, jogging with Dad or Mom, or another hobby involving exercise can help your teen get in shape and stay there. Set a good example by keeping active yourself.

5. Monitor social life. Check out your teen's friends to see if they are the kind that drink or do drugs. Don't let your teen go with them if they do. Watch your child's driving habits to ensure that they are safe. Don't let him hang around with criminals or gang members. Gently push him to pursue wholesome activities with trustworthy friends.

It's not easy to parent a teenager these days. All too often they tune out a parent's advice only to find themselves in trouble that requires Mom and Dad's help. A few subtle steps like those outlined above may help to guard your teen's health as best you can at this stage. The rest is up to time and experience.
