Run from a cold
7 Healthcast: Run from a cold
Some doctors are saying if you want to stop a cold, start walking.
Family doctor Jane Sadler's basic advice for preventing a cold centers on hygiene.
"The best thing to do is wash your hands, wash your hands, wash your hands," Dr. Sadler said.
But the feet play a role, too. More research suggests exercise can keep people from catching a cold.
And, the exercise doesn't need to be intense.
"It just means people having to bundle up during cold weather, grab their dog or a close friend and go walk," Dr. Sadler said. "We know that 30 minutes of brisk walking a day may be all you need five days a week to decrease your chances of getting a cold. Exercise increases our leukocyte counts. Leukocytes are white blood cells that actually fight infections. So by exercising, your white blood cell count temporarily elevates and that will help you in fighting your cold symptoms and getting rid of those nasty viruses."
And again, the benefit comes from exercise done at moderate intensity. Overtraining weakens the immune system and increases the chance of a cold.
While Dr. Sadler holds fast to the tried and true preventive, of washing your hands, she also advises-
"GOTC. Get off the couch," Dr. Sadler said.
And walk away from a cold.
If you're heading outdoors to get exercise this winter, there are a few things you should keep in mind. Dress in layers, drink plenty of water, and watch the surface you're walking on to avoid icy roads.(Copyright 2008 Sunbeam Television. All Rights Reserved.
