Most teens stay up late studying or hanging out with friends and don't get enough sleep. By not having a regular sleep pattern, you could be doing your body damage. You may think you're sleeping enough, but your body may not be getting the amount of rest it really needs. Teens need eight to ten hours of sleep a night to function best.

When you munch on a lot of junk food while studying, hanging out with friends, watching TV, and at the movies, you're causing serious damage to your health. Eating too much junk food can cause serious weight issues, heart disease, diabetes, and other major medical issues. To avoid them, eat some healthy munchies throughout the day, instead of just chips and sweets. Try carrot sticks, crackers, pretzels, cheese, and nuts. You can still munch, but munch healthier foods.
