Take the 2-minute tour ×  Assume , you are preparing for the
world's toughest Examination, where a lot of Hard work is
required to crack the Exam.  How many hours of sleep would be
enough to maximize your study hours but also maintaining good
mental and physical health?  share|improve this question I am a
bit confused by the second paragraph. Is this question about
physical activity? –  Baarn Dec 15 '13 at 16:50 of-course
not..that only meant under-sleeping can also have adverse effect
on physical health as well.you can't give your 100% if you are
physically sick. –  Sunny Dec 16 '13 at 2:56 Your question is
off topic then, questions should be about physical fitness, but
not about general health advice. –  Baarn Dec 16 '13 at 10:18
