Researchers are advised to sleep at least seven hours a day.
Researchers from Singapore found that lack of sleep leads to a decrease in the size of the human brain. And once again confirmed that adults to maintain health, you must sleep at least seven hours a day.
Scientists from the medical school of Duke-NUS in Singapore has studied the health of 66 older Chinese, who periodically went through the MRI scan for a long period. The volunteers talked about how much sleep they get every day. It was found that those study participants who slept the least showed the most noticeable decrease in cognitive activities of the brain. And their brain volume decreased continuously, showed that the MRIs conducted every two years.
The results of this study once again showed how harmful for human is lack of sleep. It is quite possible that chronic lack of sleep is one of the main factors leading to different kinds of disorders of the brain, including the development of dementia.
“The results of our study show that lack of sleep could be a marker of accelerated aging of the brain,” says study author Dr. June Lo. Numerous other studies have proven that an adult every day you need to sleep at least 7 hours for optimal brain function. This was confirmed by computerized testing of cognitive functions of the brain. In the coming years we are going to determine what is beneficial for cardiometabolic health in the long term.”
