Sleep less affects the brain

A recent study confirmed that sleep not only affects physical health but also has great implications for people's mental health. Following that, sleeping too little or sleeping too much is also not good.

According to the scientists' conclusion, sleep duration plays a very important role. A person who sleeps too little or sleeps too much will cause the brain to not only become "aging" quickly but also function less than normal.

Experts recommend that each of us should sleep between 6-8 hours per night . Those who are outside the allowed range (sleeping less than 6 hours / day or more than 8 hours / day) are at risk of reduced cognitive ability and memory decline when entering middle age. This is quite a serious condition, because researchers have also warned that, once the brain's functioning is impaired, physical health also decreases and people are at risk of dying. early.

Sleeping 7 hours a night helps the brain work properly.

Researchers at the University of London conducted research and showed how changing the sleeping habits within five years affect each person's cognitive function when they get old. Volunteers participating in the study must complete 6 tests of memory, reason, vocabulary, fluency, semantic proficiency and general cognitive status.

The results are as follows: People who sleep more than allowed (6-8 hours / day) score low on all cognitive tests, do not have long memory. Meanwhile, those who sleep less than the standard tend to decline their ability to reason and reserve vocabulary. Therefore, scientists have come to the conclusion, getting enough 7 hours of sleep / night and deep sleep is the foundation and the determining factor for a good brain.

Lack of sleep and insomnia is the reason why people work ineffectively, react slowly, often make mistakes in their work, lose their concentration .

Jane Ferrie, a senior researcher, said: ' The results we gained from this study mainly want to emphasize that sleep duration affects people's cognitive function later . Our busy modern life has been adversely affecting health as well as the lives of many people, so being aware of the importance of sleep is essential '.

According to scientists, the ideal time for a night's sleep is 7 hours , followed by 6 hours. Those who slept for 7 hours a night scored very high on each test performed.

For men, the results are a little different. That is, whether you sleep 6, 7 or 8 hours a night, your cognitive ability is the same, without superiority. That ability is only impaired when men sleep less or more than the recommended amount.
