As people get older, they always feel like their brains are not working properly, their memory is not good, they forget what they have said in a moment, and their attention is also difficult to concentrate. These are closely related to the aging of the brain. Unlike wrinkles on the face, brain aging can be detected by the naked eye, and many bad habits that accelerate brain aging may quietly lurk in our daily lives. How many bad habits have you developed that harm the brain? 1. Staying up late and staying up late, our internal organs are most active in detoxification and metabolism during deep sleep. Regarding the reasons for the damage to the brain caused by staying up late, scientists such as Laura D. Lewis from Boston University in the United States have published a study in the world's top scientific journal, providing a certain explanation: during deep sleep, the brain undergoes a periodic process of toxin "cleaning". At this time, brain cell activity and oxygen demand decrease, blood flows out in large quantities, cerebrospinal fluid flows in large quantities, "in one out", flushing like a "water tank" with flowing water Clear brain toxins. When staying up late, this' brainwashing 'process decreases. If you often stay up late and stay up late, it will keep the cerebral cortex in an overloaded state of work, making it easier for toxins to accumulate in the brain. Gradually, brain function will decline, accelerating brain aging. 2. The toxic substances in cigarettes, such as nicotine and carbon monoxide, are not only risk factors for various cancers, but also cause various brain damage. Smoking can stimulate chronic inflammation in the body, stimulate cerebral vasoconstriction, and reduce blood and oxygen supply. Over time, the cerebral cortex thins, stroke (also known as "stroke") increases, cognitive and memory abilities decrease, and the risk of dementia increases. Alcohol is a neurotoxic substance that can directly damage nerve cells and function. Regular drinking can also cause the central nervous system to become abnormally excited, affecting the health of the cerebral cortex, causing brain volume to shrink, damaging logical thinking ability, cognitive and memory functions, and accelerating brain aging. 3. Eating too salty can easily trigger an increase in blood pressure if the taste is too strong in daily life. Once blood pressure rises, it can also affect the blood supply to the brain, interfere with the reception of signals by vascular endothelial cells, and hinder the expansion of cerebral blood vessels. Prolonged exposure to this can also accelerate brain aging. 4. Not using the brain for a long time can also accelerate brain aging. Especially now, many people are very dependent on various electronic products and unwilling to use their brains, which can easily lead to the cerebral cortex becoming inactive, brain function degradation, and gradual decline in memory and thinking abilities. The following four methods for maintaining the brain: These activities can not only add joy to the daily life of middle-aged and elderly people, but also slow down the aging of the brain and to some extent reduce the occurrence of Alzheimer's disease. 1. Persisting in exercise can increase the blood and oxygen supply to the brain. Tai Chi, square dancing, walking, and yoga are all good exercises. Researchers from the University of Queensland in Australia report in the journal Nature Communications that brain protective factors can be released in the blood after exercise, improving age-related nerve regeneration and cognitive impairment. But it should be noted that one should have a clear understanding of their personal situation and exercise according to their abilities. 2. Don't stay up late. Adequate sleep is the key to maintaining the brain
