With the continuous extension of human life, how can we make the function of the brain not decline too fast because of the growth of age, so that the brain can prolong its life? In old age, how can we prevent Alzheimer's disease caused by brain aging? Dr. Ayman, a clinical neurophysiologist and psychiatrist at the School of Medicine, University of California, Irvine, pointed out that apart from genetic conditions, there are four factors that determine a person's brain health and longevity, and people should also protect the brain from these four aspects.
First, healthy blood circulation. The brain needs blood circulation to supply it with nutrition and oxygen all the time. All factors harmful to blood circulation, such as caffeine, nicotine, hyperlipidemia, hyperglycemia and hypertension, are harmful to cardiovascular system and brain. Maintaining the health of blood circulation is the first element of brain health.
Second, keep exercising. Physical exercise helps to accelerate and normalize blood circulation, reduce hyperlipidemia and hyperglycemia, and treat hypertension. Exercise can promote blood and oxygen supply to the brain and maintain the health of the brain. Exercise is the simplest, most effective and cheapest brain tonic in the world, and its efficacy is far better than any brain tonic on the market. Insist on aerobic exercise for more than 30 minutes every day, such as simple brisk walking, which is the best investment in your brain health care.
Third, get enough sleep. Adults should sleep at least seven hours a day. Sleeping for 7 hours every night can give your brain a full rest and adjustment. Dr. Ayman has been studying the changes of blood supply to the brain for many years. He pointed out that people who sleep more than seven hours a night have significantly less blood flowing into their brains during sleep, which is lower than those who don't get enough sleep. This shows that their brains get a more effective rest during sleep. Adequate sleep can not only make the brain work more effectively when awake, but also prevent the brain from being overtired and protect the brain from premature aging.
Fourth, positive thoughts and healthy mentality. The brain not only manages thinking, but also manages emotions and mentality. People's thinking and emotional mentality are inextricably linked. In real life, a healthy person's thoughts are always positive. Why? Dr. Ayman pointed out that the brain produces chemicals when thinking. If people's thinking activities are divided into positive thinking and negative thinking, then the chemicals produced by the brain in positive thinking activities (happiness, self-confidence, helping others, learning new knowledge, etc. ) is different from negative thinking activities (sadness, inferiority, depression, anger, anxiety, hatred, etc.). ). The former affects a healthy and good mentality and is conducive to the health and longevity of the brain. The latter affects negative mentality and is harmful to the health and longevity of the brain.
People can't live in this world without negative thoughts. The problem is to learn how to control your thoughts and emotions, resolve contradictions, and turn negative mentality into positive mentality. This is not only an important part of protecting brain health, but also an element to improve people's quality of life.
