Staying up all night may increase the risk of brain degeneration. A sleeping habit can help clear toxins from the brain.
Sleep is closely related to physical health, and good sleep quality can even help reduce health risks. American scientists successfully filmed the "purification" process of people's brains while sleeping and found that during deep sleep, the brain automatically eliminates toxins that can cause Alzheimer's disease. Some psychiatrists pointed out that deep sleep has a repairing effect on the body and is of great help to human health.
Relevant research was published in the American scientific magazine "Science" last Thursday (October 31). Researchers from Boston University in the United States used MRI scans to observe the brain conditions of 13 young people in good health while sleeping and found that during sleep A "brain purification" process occurs, during which participants are in the deep sleep stage of "Non-REM sleep".
The study used MRI to measure blood oxygen levels in their brains and found that spinal cord fluid flows in and out of the brain during sleep. Studies have pointed out that when people enter deep sleep, their body functions also enter a resting stage, which means that the brain does not need too much oxygen, reducing the blood flow to the brain. Instead, cerebral spinal cord fluid will flow into the sleeping brain in large amounts every 20 seconds, replenishing the brain. space left. Research shows that when cerebral spinal fluid flows into the brain in large amounts, it can cleanse the brain of accumulated harmful substances, including the toxin beta-amyloid (Beta-amyloid) that damages cranial nerves and causes Alzheimer's disease.
Deep sleep can increase melatonin and repair body functions
Chen Zhongmou, a specialist in psychiatry, said in an interview with Qingbao that although there is currently insufficient evidence to prove whether the cerebrospinal fluid guided by deep sleep can remove toxins that cause Alzheimer's disease, deep sleep generally has a negative impact on various organs of the body. All have benefits. Dr. Chen Zhongmou pointed out that when people enter deep sleep, the pineal gland in the brain secretes pinealin (melatonin), a type of hormone that induces the body to release growth hormone, which is used to repair the body. Function, helps the recovery of various organs of the body and removes toxins from the body.
As for how to enter deep sleep? Dr. Chen Zhongmou pointed out that deep sleep accounts for about 20 to 30% of sleep time, and the length varies from person to person. Generally, deep sleep can only be entered at night, and it needs to be done in a dark place. Because of factors such as the human biological clock, If people sleep during the day, even in a completely dark place, they may not be able to effectively enter deep sleep.
