Immune System

Exercise in the form of running helps the immune system fight off bacterial and viral infections. Running decreases the chances of developing heart disease, osteoporosis and cancer. It helps flushing out the bacteria from the lungs; thus, flu, colds and other airborne illnesses are prevented. Cancer causing cells are prevented since running helps in increasing the output of wastes such as urine and sweat.

Running also sends out antibodies and white blood cells through the body. They circulate more rapidly, and the increased rate of blood flow triggers the faster reactions of the antibodies against harmful bacteria.
