How long of sleep should an individual have? There is no positive response to this inquiry. Sleep needs change from one individual to the next. A few people may feel crisp significantly following 5-6 hours of sleep while the others might be sleepy much following 10-11 hours of sleeping. The way to comprehend ones sleep needs is that in the event that you are feeling worn out, sluggish during the day time and can’t focus on your work, at that point likely you need more sleep.
