A report published today in a leading medical journal claims that working out can be harmful to your health. For many years doctors have told people that exercising regularly is good for your health. However, they have found proof that exercising too much can have damaging effects on the body. When we exercise, chemical called endorphins are released into the brain. These endorphins energize the body, and give us a lift or high. It is this ‘high’ that people who exercise too much become addicted to. Although scientists say that experiencing this lift regularly is good for health, evidence shows that too much of it is damaging. People who are addicted to exercise should not quit altogether. Doctors advise them just to stop exercising too often.
