While many people are physically active in high school, there are always many things

for teens to compromise their healthy lifestyle. 36

Get plenty of rest. With homework and social commitments, teens in high school have a tendency to stay up late and rise early. 37 Then go to sleep early enough, turn off the television or radio and unplug the phone to prevent your sleep from being disturbed.

38 Teens are well-known for living on a diet of junk food and soda. Drink plenty of water and eat whole grains and vegetables daily. If you mainly eat nutritious foods, the occasional fast food hamburger or late night pizza won't hurt you.

Say no to cigarettes and alcohol. Lifelong habits start during high school years, so make sure the habits you are forming are good ones. Getting hooked on cigarettes and alcohol at a young age can lead to an adulthood spent battling addictive habits. 39 Exercise regularly. Physical activity helps build a strong body and mind. Teens who exercise throughout high school benefit from a healthy body and a mind that is more at ease

with less stress.
