The risk of senility depends on the duration of our sleep dementia and some other age-related brain disorders. That is why it is necessary to spend at least 7-8 hours on a night's rest.

Scientists from Washington University in St. Louis in the course of a study proved that there is a so-called average range or golden mean for the duration of night sleep.

With its observance, the cognitive abilities of the brain remain stable for a long period of time. The authors of the study observed the sleep of 100 elderly people who had previously been checked for various cognitive impairments and symptoms of Alzheimer's disease. It turned out that spending 6 to 8 hours on sleep was the best way to preserve the brain's functionality.

If a person slept less than five and a half hours, his cognitive abilities deteriorated, even taking into account such factors as age, gender and senile dementia. This also applied to those people who slept too much.

Sleep excess also led to cognitive impairment. Golden sleep duration is called exactly 7.5 hours. It is desirable to sleep not much more, but also not much less.

Another study suggests that the quality of sleep is of key importance in preserving intellectual abilities and memory. If we sleep regularly, that is, we rest adequately, the body is completely cleansed of all kinds of dangerous toxic particles in the brain, the accumulation of which can lead to serious problems in old age.
