1, improve blood circulation in the brain: People who exercise regularly should know that the first benefit of exercise is to improve heart and lung function, so that their myocardium is developed, their blood supply is sufficient, their lungs are muscular and their vital capacity is increased. But also can improve blood circulation and increase red blood cells, white blood cells and hemoglobin in blood. These are only important nutrients that provide energy and oxygen for the brain and nervous system, so exercise and fitness can not only improve the blood circulation of myocardium, but also provide fresh vitality for the blood in the brain.

2. Give your brain a rest: Many people choose to do yoga to relax their brains when they are depressed and stressed, or choose to vent their emotions by sweating, running, cycling and boxing. Relax and rest their brains. This is because the excitement brought by exercise can effectively stimulate the cranial nerves and protect them to some extent. Therefore, regular exercise and fitness can make the mood more pleasant.

3, prevent brain aging: friends who like to observe the elderly will have an interesting discovery. Old people who often go out to exercise will have a better spirit, and the state of talking to young people is also very energetic. And those old people who are sedentary all day, or those who are bedridden for a long time, some young people answer irrelevant questions when talking to them. This is because as people grow older, organs in all parts are degenerating, and the brain is aging faster than other organs. Regular exercise can make the blood in the brain be constantly replaced and replenished, and it can also make the nerve reaction of the brain more rapid and agile.
