Allowing the body to rest between 7 and 8 hours a day allows a person to maintain a good quality of life and enjoy great health, both physical and mental. On the other hand, sleeping less than 7 hours and more than 9 hours can be counterproductive. By having fewer hours of sleep, the body will not be alert enough to perform daily tasks.

Development of Creativity

Just as in sleep cognitive restoration occurs, the mind is also strengthened. The rest produces a cerebral reorganization, which allows having more cleared what one wishes to do. During the day there are many ideas and knowledge that are acquired, so a few hours of sleep allow the restructuring of ideas and the development of creativity.

Fewer hours of sleep affect the immune system, so if a person has a disease and does not get enough sleep, recovery will be slower. Even, the quality of sleep allows you to lose weight. An investigation by the University of Chicago (United States) found that those who sleep at their hours manages to lose excess fat, while those who sleep badly lose muscle mass.


This is due to an alteration of the hormones due to lack of sleep. With fewer hours of rest, the hormones that cause you to feel hungry increase, while the hormones that determine that your appetite has been satiated decrease.

The truth is that sleep well allows you to enjoy good health, therefore, away diseases that deteriorate the body, allowing you to live quietly. Moreover, People who sleep more hours have a higher concentration of leukocytes in the blood and suffer fewer infections. When we are sick we need to repair our defenses through sleep.

It is important, even more for athletes, to rest enough, since it is in a deep sleep that physical recovery takes place. This non-REM sleep tends to increase when more physical exhaustion is experienced. In this case, athletes would be an exception to the rule of 8 hours a day, since to experience greater physical activity, they may even need between 10 and 13 hours of sleep depending on the exercises that have been performed.
