Get Off The Couch
Studies show that moderate exercise boosts the immune system. Why? It’s believed that exercise may help boost your immune system in the following ways (these are only theories):
- Physical activity may help flush bacteria out of the lungs and airways. This may reduce your chance of getting a cold, flu, or other illness.
- Exercise causes change in antibodies and white blood cells (WBC). WBCs are the body’s immune system cells that fight disease. These antibodies or WBCs circulate more rapidly, so they could detect illnesses earlier than they might have before. However, no one knows whether these changes help prevent infections.
- The brief rise in body temperature during and right after exercise may prevent bacteria from growing. This temperature rise may help the body fight infection better. (This is similar to what happens when you have a fever.)
- Exercise slows down the release of stress hormones. Some stress increases the chance of illness. Lower stress hormones may protect against illness.
Pretty cool, huh? Just don’t overdo it or that boost can turn into a weakened immune system.
Cheers to better health!
