Our grandmothers always said that 8 hours of sleep is necessary to feel good, but were they right? This is the question raised by a group of British researchers, who analyzed a large sample of people, and came to truly amazing results.
Well let’s forget about 8 hours of sleep, that’s how long it takes to stay in the arms of Morpheus to be able to stay young and healthy. Because not everyone knows that one of the number one causes of premature aging is a lack of adequate rest. So good nutrition, daily exercise and skin care become completely useless if you don’t get enough sleep. There is even evidence that reducing sleep to just 5 hours negatively affects heart health. British experts compared the amount of rest to the brain activities of a large number of people, more than 500,000, between the ages of 38 and 73.
From this in-depth analysis, it was found that a certain area of the brain shrinks in size, and therefore in amplitude, if you sleep too little, but also for too long. This area is called the hippocampus because it resembles a seahorse. Well, this organ is considered the seat of memory. It is easy to understand how reducing its size leads to memory loss in one form or another.
Let’s forget about 8 hours of sleep, here’s how much sleep you need over 40 to stay young and active
No memory problems were found, despite age, in a group of people who rested on average the same number of hours. It has also been proven that they are quicker to analyze everyday problems and find the fastest and most effective solution. The skin and vision are also younger and deteriorate much more slowly.
Therefore, those who got the best results on cognitive tests were the group of people who rested an average of 7 hours per night. Furthermore, it was found that middle-aged women, due to their differing hormonal balance, had to sleep between 11 and 13 minutes longer than men to obtain the same results.
So we remember that in order to stay young and in good shape, a good rest is as important as a healthy diet and adequate physical movement.
