Exercising frequently can be a positive habit, but if a person becomes addicted to it, it also has negative effects. Exercise addiction is not easy to identify because, like any other addict, they tend to deny having a problem. This addiction is referred to by various names such as exercise addiction, exercise addiction, compulsive exercise, compulsive athleticism, compulsive exercise, and exercise abuse. "Men and women are equally prone to exercise addiction, which affects about three percent of the population, according to a University of Southern California study. Exercise addicts typically exercise two or three hours a day, six or seven days a week” (Seymour) Exercise addicts, of both sexes, don’t understand the difference between pushing their limits and surpassing them. These addicted people will use exercise to avoid life problems in relationships, low self-esteem, and problems with family or work. Various warning signs of a person addicted to exercise include: always working out alone, isolated from others, always following the same rigid exercise regimen, exercising for more than two hours a day , repeatedly. They are obsessed with losing weight or burning calories. Continue to exercise when you are sick or injured, until you feel pain and beyond. Start skipping work, class, or social activities to workout, exercising more after each meal. Even though he lost a lot of weight, he was never satisfied with his physical performance. They experience feelings of guilt and anxiety about missing a workout. Additionally, he doesn't like to sit still or relax because he fears he won't burn enough calories. People with these warning signs will continue to exercise despite several different theories that attempt to analyze the origins of this disorder. OCD can be attributed to stress, which can intensify or provoke symptoms. Experts in this medical field also identify brain dysfunctions such as encephalitis, head trauma, or any other brain disorder as a possible cause of brain abnormalities that can lead to OCD. The patient's genetics may also play a relevant role in the development of the disorder. Experts believe that a person can inherit a tendency to develop OCD under certain conditions. According to the serotonin theory, an imbalanced level of chemicals in the brain can also be attributed to a person suffering from OCD. Finally, learned behavior is also a crucial factor that must be analyzed. If a child is taught that he may be predisposed to fear, he develops compulsions to reduce said fears when negative thoughts arise..
