Fight Colds With Exercise

A regular exercise program can do amazing things for your health, like beating Alzheimer's and diabetes. Moderate exercise also boosts the immune system, specifically, of postmenopausal women, according to a new study.

Researchers monitored the health of 115 older, overweight and sedentary women, one of whom smoked and took HRT, for about a year. Half attended a weekly stretching class, while the rest participated in a moderate-intensity, aerobic exercise group.

Although patients in the latter group were asked to exercise about 45 minutes a day at home and the gym five days a week, they were only able to reach the 30 minute mark per day, with brisk walking accounting for the bulk of their body work. Still, that was enough to strengthen the immune systems of women in the exercise group over time and successfully ward off colds.

More evidence, it's crucial to treat exercise like a drug that must be properly prescribed, monitored and maintained for you to enjoy the most benefits. That means, however, you can't bank exercise either.
