8 Hours or 7 Hours of Sleep, What’s the Difference?

This panel reviewed over current scientific publications meta-analyses and voting on the appropriate amount of sleep required.

The panel revised the sleep ranges for all six children and teen age groups. They also included a new category younger adults While this may be a credible source, this is only one source. Their recommended amount of sleep was very consistent.

Both being very credible sources and very similar in recommended sleep time, this similarity shows that this is a very good approximation to how much sleep each age group should spend sleeping.

The range for hours of sleep each night for people aged is hours. While 7 is included in the range, should it be focused on more and used as a target?

While college is all about inconsistency, you need 7 hours of sleep every night to reap the benefits of the 7 hours.

So party hard, study hard, sleep in late, but to get the benefits of the 7 hours, it needs to be done consistently. To conclude: These two studies both very strongly support that sleeping 7 hours, instead of the much more commonly hear 8 hours, might prove to be beneficial in the long run for increased mortality and better cognitive functioning.

But like I said before to all you crazy, sleep-deprived college students, the 7 hours needs to be consistent for it to be beneficial. While there are certainly going to be some nights 7 hours of sleep is really impossible, aim for it. Skip to toolbar Sites at Penn State.
