Teen | 13-18 years | 8-10 hours |
Adult | 18 years and older | 7 hours or more |
A recent report shows that many teenagers in America are not getting therecommended amount of sleep. Here are the results.
Why is it hard for teens to get good sleep? There is no single reason. Instead, several factors contribute to this problem. One of them is late bedtime and early school start times. Now, more and more teenagers are developing a habit of being "a night owl", staying up later at night and sleeping longer into the morning. If allowed to sleep as they wish, many teens would get eight hours or more a night, but most school start times require them to wake up much earlier in the morning.
The use of electronic devices like the smartphone and computer is another factor. Research has found that 89% or more of teens keep at least one device in their bedroom at night. Screen time late into the evening can cause sleep problems. Using these devices can keep teens excited and unable to fall asleep. Sudden phone messages can disrupt sleep. And being in the light from smartphones also makes people feel less sleepy.
So teens should improve their sleep environment and habits to get better sleep. Here are some tips.
* Get eight hours of sleep a night on weekdays and weekends.
* Put away electronic devices at least a half-hour before bed. Keep them on silent during the night.
* Keep your bedroom cool, dark and quiet.
