First, by eating. Eat more foods that are good for the brain. This kind of food is mainly rich in dha, because DHA, as one of the important substances for brain development and growth, is the main component of human brain cells and the basis of brain phosphate and brain cell membrane. If DHA is deficient, it will lead to brain dysfunction, such as decreased memory, decreased information transmission ability between brain cells, and decreased sensation. For example, fish, egg yolk, walnuts, bananas, fungus, milk, garlic, sesame, pumpkin, sunflower seeds, kelp, lean meat and oats are rich in dha. Never eat junk food, the substances in it are harmful to the brain.

Second, rely on practice. As the saying goes, people who use their brains are not old. A full brain is light, and a strong brain is strong; If the brain is empty, it will relax and lie down. "Light strength and more strength" refers to the physical and mental movement. When something goes wrong, the brain is dissatisfied, the thinking is sluggish, the spirit is not full, and the action is slow. Usually cultivate various hobbies to keep the brain active, such as playing chess, reading books, reciting, chatting, playing the active brain cell training content built into the whole brain speed reading memory tool such as jint.

Third, rely on it. Exercise more at ordinary times and pay more attention to health. Health preservation is to form good living habits, and usually take part in aerobic exercise. Aerobic exercise can send more blood to the brain, bring in more oxygen and glucose, and enhance brain function. As long as people are not disabled, they can do what they can. Such as walking, jogging, gymnastics and other outdoor activities.
