  • 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.

  • Your question is off topic then, questions should be about physical fitness, but not about general health advice.

Usually sleeping 8 hours are good for health, but at least 6 hours are compulsory, otherwise you will feel tired after few days and may effect your studies. so sleep at least 6 hours
