6 "Bests" About Kids' ExerciseAt least one hour of physical activity a day helps kids to:
- Feel less stressed
- Feel better about themselves
- Feel more ready to learn in school
- Keep a healthy weight
- Build sturdy muscles, bones, and joints
- Sleep better at night
Getting enough ZZZZsNodding off in school may not be the only outcome for otherwise healthy teens who don't get enough sleep. A study funded by the National Heart, Lung, and Blood Institute (NHLBI) links poor sleep in teens (ages 13 to 16 years old) to higher blood pressure. Researchers found that teens who got less than 6 ½ hours sleep were 2½ times more likely to have elevated blood pressure than teens who slept longer. Also, teens who had trouble falling asleep or staying asleep were 3½ times more likely to have high blood pressure or pre-high blood pressure than teens who slept well. These results are similar to findings from other studies in adults. High blood pressure, if left untreated, can increase the risk of stroke and heart diseases later in life.
- Sleep Facts: School-aged children and teens need at least nine hours of sleep a night. Adults need seven to eight hours of sleep a night
- Sleep Tips: Set a sleep schedule; going to bed and waking up the same times each day. Keep room temperature on the cool side. A TV or computer in the bedroom can be a distraction.
