Minimum 6 hours sleep in a day is good for nine year old girl's health.
they need about 6 hours of sleep
about 10 hours of sleep
they're human aren't they? so wouldn't the answer be how many hours of sleep does a human need? and the answer is about 8 hours.
You need 8 hours of sleep, and you have to be in deep sleep at 1-4 a.m.
it need 7hours sleep for health
at least 9 or 10 hours to get enough sleep
6 Hours of sleep is enough
uhh, for your information, you should go to the nine year old girl and ask her " how much do you need to sleep" I think tht will help . wow, you have to think, well how much do YOU need to sleep. & then come to a nine year old girl. cuz duh EVERYONE needs to sleep for like 8 till 9 hours. THINK NEXT TIME !! sholoon khara
