Too Much Sleep how Bad it is for Your Brain

 

Without a doubt, sleep is good for us. Getting enough is essential for staying energized, mentallypeople have  long talked about the importance and getting enough of it, but what if you tend to sleep more than the recommended 7-8 hours? ...will rhere be any side effect?...well i have the answer here;A new study  in Havard suggests that might also negatively affect your memory and thinking.The Harvard-based Nurses' Health Study, published in the Journal of the American Geriatrics Society, asked over 15,000 women (ages 70 and up) about their sleep habits in 1986 and 2000. The researchers then tested the nurses' cognitive functions three times over a six-year period. Those who slept very little (5 or fewer hours a day) or very much (9 or more hours a day)  were said to performed significantly less well on those memory and thinking tests than those who slept 7 to 8 hours a day. do you  now know the The scariest part?  according to report,The researchers estimate the under- and over-sleepers were mentally two years older than those who slept the recommended amount.

The study also suggests poorer cognitive skills if your sleep duration changes by 2 hours or more over time (something that often happens as you get older), rather than having no change in your sleep amount.PThe Harvard Health blog reasons that too much sleep is often associated with poor sleep quality, which in turn could affect memory and thinking.P
While, as with most other studies, correlation doesn't equal causation, and the study subjects were specifically elderly females, the takeaway for us all is to try to improve sleep quality, especially as we age.
