The Journal of Neuroscience published a scientific article about the important changes that occur in the brain after a night without sleep, which indicates the effect of lack of sleep on the brain, and the researchers confirm that the changes that occur in the brain after a night without sleep are equivalent to the changes that occur within 1-2 hours. A year of human aging, but these changes disappear after a good night's sleep, according to Russia Today.
The researchers studied changes in the brains of 134 people who were divided according to the duration of sleep and who had not slept at all.
It became clear to them that "aging" appeared in those who had never slept, and that these changes disappeared after they slept 10 hours. Sleep disorders occur in people with neurological diseases and mental disorders. Because lack of sleep affects not only the brain, but also other organs and systems: cardiovascular, immune, respiratory, and endocrine. Chronic sleep deprivation may also lead to higher blood pressure and cholesterol levels, and an increased risk of type 2 diabetes and obesity. In general, it is difficult to name something in our bodies that is not affected by sleep.
The number of hours of sleep a person needs is as follows:
* From 4 months to a year – 12-16 hours
* From 2 to 5 years: 11-14 hours
* From 5 to 12 years: 10-13 hours
* From 12 to 18 years old 9-12 hours
* From 12 to 18 years old, 8-10 hours
* Adults over 18: 7-9 hours.
