between 5-7 hours of sleep. Children need at least 7-8 hours of sleep
Do you need 8 hours sleep every night? Nope....You can sleep only 4 hours a day like Napoleon Bonaparte did or 10 hours of sleep in a day just like Albert Einstein. You can set your alarm for when you go to bed and when you would like to get up from bed that fits your lifestyle. Remember... the most important thing is that you have a good night's sleep!
My doctor has told me that tweens need 9 hours of sleep a night! A Sleep Doctor should tell you to sleep 10 hours of sleep not 9 hours. Now Adult can sleep up to 6 hours, there bodys don't need that much sleep:)
8 hours a night
Ages 13-18 need about 8 to 10 hours of sleep. Adults between 25 and 64 years of age need an average of 7 to 9 hours of sleep per night. Adults 65 and older need 7 to 8 hours per night.
The number I've heard is generally 8. It varies, but that seems reasonable to me. I think the amount of sleep you need depends on how much work you do in a day.
Kids and teens need 10 hours of sleep per night in order to be alert and healthy!
