Walk away from a cold
Want to ward off those winter colds, especially if you are a woman older than 50? A new study indicates that if you walk fast, your nose may not run.
Researchers at the Fred Hutchinson Cancer Research Center in Seattle found that a group of older women who did moderate exercise — generally brisk walking — had half the risk of catching a cold compared to a group that did not exercise.
The women who exercised did it regularly, 45 minutes a day five days a week.
But don't think you can further cut your risk by ramping up the regimen.
Researchers pointed out that previous studies showed that intense workouts could deplete the immune system and make a person more at risk for colds.
One word of warning: Don't hang up your sneakers once cold season is over. Researchers found that the protective benefits of exercise increase over time.
