Running can reduce the risk of cardiovascular and respiratory diseases, improve cardiovascular fitness, as well as reduce total blood cholesterol. Even people who have already experienced a heart attack are 20% less likely to develop serious heart problems if more engaged in running or any type of aerobic activity.
Running can assist people in losing weight, staying in shape and improving body composition. Research suggests that the person of average weight will burn approximately 100 calories per mile run. Running increases one's metabolism, even after running; one will continue to burn an increased level of calories for a short time after the run.
Running can also have psychological benefits. It is frequently recommended as therapy for people with clinical depression and people coping with addiction. It can even have a longer-lasting effect than anti-depressants.
