One obvious problem is that these people tend to exercise excessively. Researchers have found that sports addicts often suffer psychological harm. In order to change their negative emotions, they will rely on exercise to divert their attention, and training has become a mechanical activity. Over time, the threshold of excitement will gradually increase, and the body can withstand higher intensity training. In order to achieve the original degree of stimulation, these people can only increase the amount of exercise, leading to excessive exercise. Excessive exercise makes ligaments, tendons, joints, heart and bones tense, leading to an increase in the incidence of heart disease and osteoporosis. Not only the physical function is damaged, but also sports addiction will have negative social impact. Addicts avoid socializing because sports attract them more than family, friends and work. After lack of social activities, these people will become more and more introverted and depressed. The researchers also found that those who exercise too much, sleep cycles and eating patterns will also be disordered, and some people will even suffer from anorexia. Therefore, exercise is certainly a beneficial exercise, but if you rely too much on it, it will do great harm to your body and mind.
