Scientific studies indicate that physical activities can help by flushing harmful bacteria out of the lungs. Hence, people can decrease chances of having a cold, flu and other airborne illness.

Exercise also sends white blood cells (defense cells of the body) and antibodies through the body at a rapid rate. Since, these white blood cells or antibodies circulate more quickly, they can detect illnesses and conditions earlier than they can normally. Besides, increased circulating blood rate may trigger the hormone release that warns immune cells of intruding viruses and bacteria.

The rise of body temperature while exercising can prevent the growth of bacteria, thereby allowing the human’s body to fight off the infection effectively. This is similar to fever symptoms in the body.

Next to the facts of exercise and immune system for illness prevention, exercise can help slow down or prevent the release of hormones related to stress. And in reality, stress is a factor that increases chances of illness.

However, while exercise is very beneficial, don’t overdo it. Those who exercise regularly are often cautioned not to do vigorous exercises in the hopes of boosting the immune system benefits. Long-term exercises such as intense gym training or marathon running may actually lower amounts of white blood cells that circulate through the body and boost the presence of hormones related to stress.

Studies also have indicated that those who benefit from starting or sticking to an exercise routine are people who go from a “couch potato” lifestyle to an energetic lifestyle. Normally, a moderate exercise program may consist of:

  • Daily walks ( about 20 – 30 minutes a day)
  • Biking alone or with children several times per week
  • Playing golf a few times a month regularly
  • Following a gym workout routine every other day

In short, exercise can help people feel better about themselves, just by making them feel healthier and more energetic. So go ahead, join an aerobics center or go for a walk and feel healthier and better for it.

If you have one or some of these symptoms, let your condition be recovered totally, then start your exercise program later.
