How Much Sleep Do We Need..??

Hey guys,
So are you ever in doubt that how much sleep do you need..?? So is the case with every student. Today is the Era of time management. But sleeping  less and devoting more time towards studies is not so good. Well after 2 weeks your time table will start to crash or your studying  capacity  will drop down gradually. So you should seriously plan out your time table and don't drop down your sleep time. Well everyone  suggests a average sleep of 6 hours. But I would  suggest 1 to 2 hours extra lap in that. It means a continuous sleep of 7 hours will do your job very well....
