How Much time a normal person have to sleep

Thanks for your response Well If some one sleeps more than 6 Hrs , any problem

No problem at all. Some says sleeping more than 7 to 8 hours per day has been consistently associated with increased mortality. While the average normal amount of sleep is around 7.5 hours per night, there are some people who do just fine on 5 hours per night, and some who require as much as 9 hours per night. The key is to find the right amount for you. The best way to tell is by seeing how you function during the day. For example, if after 6 hours of sleep you feel refreshed in the morning and awake during your daylight hours, then you don't need more than that. If, on the other hand, you need 9 hours a night to feel refreshed and to function well during the day, then that is what your individual requirement is and sleeping the "normal" amount of 7.5 hours per night will actually leave you sleep deprived.

Thanks Mr Zubair for the comment well u have to arrange some more time for sleep 3-4 hrs r very less, also not good for health
