How long do you need to sleep? The answer from England

Indeed there is whoto demonstrate his industriousness, he boasts of sleeping a few hours every night and get up very early in the morning in order to be more “performing”. Well, know that – probably – whoever tells you these things is lying.

Hours of sleep, the duration varies according to age

Too much? Too little? How long are we sleeping? The study in question seems to have found answers. The first is that there is no ideal time for everyone; the reason is that each age has a sleep duration of reference. By cross-referencing sleep data and claims from 500,000 aged adults between 38 and 73 years old in fact, it was concluded that in this age group you should sleep 7 hours every night. No more and no less.

Still analyzing these data, the scholars also followed the brain health of the individuals in question and noticed a very interesting phenomenon. The hippocampus – the area of ​​the brain most affected by sleep – it shrinks in size if your sleep is less than or more than 7 hours. These people have in fact been subjected to particular cognitive tests and guess who got the better results? Own who sleeps 7 hours, not who sleeps 6 or 8.

The reasons could be many regarding a shorter sleep duration than expected. First, the brain would not be able to effectively eliminate them toxins; moreover, an interruption of deep sleep would be detrimental to the consolidation of information and of the memory. However, there are no specific reasons for the shrinking of the hippocampus for those who sleep too much.
