This is a minimal "cognitive needs" test. There are two kinds of people, thinkers and non-thinkers. Thinkers like to think, which is a pleasure. Non-thinkers like direct stimulation and avoid thinking. This is similar to the division between introversion and extroversion, and energy flows in different ways. Some people react directly to external stimuli, while others pause to calculate and think after being stimulated. In this way, introverts actually have an advantage. Exercise can promote brain health. Why don't mental workers like sports? 20 15 Todd mcelroy, an American psychologist, found 30 "thinkers" and 30 "non-thinkers" among college students and put on wristbands to monitor the amount of exercise. A week later, data feedback showed that non-thinkers exercised more than thinkers from Monday to Friday, but there was little difference on weekends. Exercise can not only improve the blood supply to the brain and make its blood sugar supply more stable, but also regulate the secretion of serotonin, dopamine and norepinephrine, making people feel happy and relaxed. Athletes have better long-term memory and concentration than thinkers.

Interestingly, introverts prefer thinking, but exercise can promote the vitality of the brain, while extroverts don't like thinking, but extroverts like sports and exercise their brains, which offsets the disadvantages of not thinking. Since self-control is a physiological index, you should exercise. This makes many people daunting. When it comes to sports, people first think of explosive anaerobic sports such as sprinting and loading, or sports such as long-distance running that challenge the limits of the body, but it is not. Exercise doesn't let you build a bodybuilder's figure, nor let you sprint 100 meters or run a marathon, but let you exercise your muscles. James hill did an interesting experiment in America. He found that 18 to 25-year-old women walk about 5000 steps a day on average, while men walk 6000 steps, while obese people walk less than the average person 1500 to 2000 steps. How far is 2000 steps? According to the calculation of 0.5 meters per step, that is, walking one kilometer every day will not make people fat. This is the difference between obese people and normal people.

It takes fifteen minutes to walk the dog, visit the park, or get off at work early, from a fat figure to an ordinary figure. So, the activity is not that difficult, is it? The reason why we are afraid of exercise is because the energy of the body is too scarce, which leads to no energy to start exercising. But I believe that if you walk an extra kilometer every day, your physical fitness will begin to recover slowly, aerobic exercise will naturally enter your plan, and you can get better without any willpower. When exercising, when the oxygen inhaled by the human body is equal to the demand, it is called aerobic exercise. Simply put, aerobic exercise refers to any exercise that lasts more than 15 minutes, has low intensity, has spare capacity to continue doing it, and is a little sweaty but not tired. If you do 30-40 minutes of low-intensity aerobic exercise three to five times a week, you can fall asleep faster and the quality of sleep will be greatly improved.

Self-control, memory, attention and creativity will also be improved. Low intensity, 15 minutes and no fatigue are all good aerobic exercises, including jogging, swimming, jogging, ball games, walking dogs, housework, cycling and so on. In aerobic exercise, we should pay attention to keep the heartbeat within 150 times per minute to obtain blood and provide enough oxygen for the myocardium. Otherwise, exceeding this range is anaerobic exercise. If the fatigue caused by exercise the next day cannot be eliminated, it means that the exercise has been excessive.
