Exercise won't keep colds away

October 12, 2006

Exercise may be good for nearly everything else, but it won't protect from colds this winter. A six-year study of about 14,000 middle-aged and older males found that moderate physical activity did not lower their risk of contracting colds. In fact, excessive training may make an individual more vulnerable by suppressing the immune system. The study also found that subjects taking antioxidant supplements vitamin E and beta carotene had a higher risk of colds when they engaged in "heavy exercise at leisure." Penn State Hershey Medical Center recommends those who want to avoid colds wash hands often, drink plenty of fluids and eat plenty of fruits and vegetables rich in phytochemicals, those dark green, red or yellow in color.
