Guess what?Â Going out in the cold can help prevent colds.Â Actually, it is daily walking which prevents colds, and this can be done indoors or out.Â From Fitness on msnbc.com:
People who exercise five or more times a week get fewer and less severe colds than those who work out one or fewer times a week, said Dr. David Nieman, director of the Human Performance Laboratory at Appalachian State University in North Carolina.
The benefits of walking seem never ending. To benefit from walkingÂ to prevent colds, daily brisk walks at least five times a week lasting at least 30 minutes are needed. Researchers postulate that the regular exercise stimulates the immune system to fight off infection. Walking doesn’t just prevent colds, but shortens the length and lessens the severity of respiratory illness as well. Regular ambulation shortened the length of colds by 43% to 46%,Â from a study published this month in the British Journal of Medicine.
Forget the zinc and the vitamin C.Â Get out and walk, either outdoors, in the mall, or on a treadmill. Maybe you’ll get fewer and less severe attacks of cabin fever this winter as well.
