Do you enjoy a walk in the winter air? While it is important to dress warmly, using the layer technique, but did you know that the cold, arid air can dry out and irritate your bronchial passages? Tina Vindum, author of Outdoor Fitness: Step Out of the Gym and Into the BEST Shape of Your Life, recommends covering your mouth and nose with a scarf before heading out for cold-weather exercise.

Wearing a scarf over your mouth and nose, heat and water will be trapped in the material every time you breathe out.

A very good ideal, because then that moisture and heat are available to warm and humidify your next breath on the way in. And that’s much easier on your respiratory system.
