Moderate exercise can boost your body’s immune system naturally, but you do have to be careful not to over do things. If you exercise too much, or for too long, you can actually lower your body’s natural immunity for short periods of time.
When you exercise, your body’s blood starts pumping through your veins faster and stronger. This exercises the heart, and carries nutrition to all the areas of your body. This increased blood flow also helps pick up toxins, wastes, germs and other harmful bacteria from your muscles and organs. And the body’s immune cells circulate more freely through the blood system too, which helps them kill the potentially harmful bacteria.
