We've all heard the best way to keep your nose from running is to keep your hands washed and free of germs.
Dr. Jane Sadler a Family Practice Physician agrees that hand washing is important, but your feet can help too whether they're washed or not. She says that scientists are learning another way to stop a cold is to start walking.
"It just means people having to bundle up during cold weather, grab their dog or a close friend and go walk. We know that 30 minutes of brisk walking a day may be all you need five days a week to decrease your chances of getting a cold. Exercise increases our leukocyte counts. Leukocytes are white blood cells that actually fight infections. So by exercising, your white blood cell count temporarily elevates and that will help you in fighting your cold symptoms and getting rid of those nasty viruses." says Dr. Sadler.
She adds the benefit comes from moderate exercise. A really intense exercise or overtraining can instead weaken the immune system, thereby increasing your chance of a cold.
