Immune Support with Exercise
With the recent news about the “swine flu” everyone seems to be a bit worried. Remember that we are always exposed to viruses all day long, but some people seem more susceptible to catching colds or the flu. A strong immune system can combat these viruses.
The following factors have all been associated with impaired immune function and increased risk of catching colds: old age, cigarette smoking, stress, poor nutrition, fatigue, lack of sleep and over-training.
More and more research is finding a link between moderate, regular exercise and a strong immune system.
Early studies reported that recreational exercisers reported fewer colds once they began running. Moderate exercise has been linked to a positive immune system response and a temporary boost in the production of macrophages, the cells that attack bacteria. It is believed that regular, consistent exercise can lead to substantial benefits in immune system health over the long-term.
Recently studies have shown that there are physiological changes in the immune system as a response to exercise. During moderate exercise immune cells circulate through the body more quickly and are better able to kill bacteria and viruses.
After exercise ends, the immune system generally returns to normal within a few hours, but consistent, regular exercise seems to make these changes a bit more long-lasting.
There is one caveat however, too much exercise can be harmful to your Immune System so don’t overdo it!
