How Much Sleep Do You Actually Require In A Day?

Imagine pulling an all-nighter at your office and all you want to do is go home and get some sleep. However, your boss likes you too much and has scheduled a big client meeting for the next morning. You have no option left but to cut out your sleep and still make it through the day without passing out in the boardroom. Chances are that you will be feeling exhausted and will want to finish your day as soon as possible, but you still manage to do it, right?

After a busy week at office, you want nothing more than to catch up on sleep by having a good rest on the weekend. You happily oversleep on Saturday and Sunday, and once again feel tired, so you don’t have any energy to do anything fun on the weekend. Before you know it, Monday is back! You’re back in the office and the whole cycle starts over.

How Much Sleep Does a Human Being Actually Require?

Well, we all know that a good amount of sleep is required for the proper functioning of the body. However, until recently, scientists did not know the exact reason why sleep was so important for us. It has been seen that a lack of proper sleep renders a person tired and lethargic throughout their entire day, but the exact reasons were somewhat murky. If you’re a student, then this exhaustion would mean an inability to concentrate on studies, or if you’re a working professional, then it would likely mean a reduction in productivity.

Most studies show that the average human needs 7-8 hours of sleep per day, and a person who regularly sleeps less than 7 hours has a higher chance of developing diabetes, heart disease etc. On the flip side, however, too much sleep is also bad for you. A person who sleeps more than 8 hours a day can have the same risk of diabetes, heart disease etc.

Not all individuals require 8 hours of sleep.  Some can function with less sleep and this level of necessary sleep also depends on age and genes that will determine how much sleep a person requires. In other words, there is not a definite number of hours that you must sleep to make sure that you stay disease-free. However, to be on the safe side, catching a good night’s sleep of around 7 to 8 hours is never a bad idea.
