Very, very important to stay very well hydrated before & after physical exertion in the cold.
But MOST IMPORTANT; need to prevent cold air from going into your lungs or minimizing cold air intake so…breathe thru you nose at all times outside AND warm your intake air by wearing a scarf around your nose/mouth to warm the air you’re taking in. A neck gator, scarf, bandana all would work. Not too tight but enough to create a nice pocket of warm moist air around your mouth. Even a cheap face mask like the paper disposable ones. Altho’ we know that if we are really exerting they don’t cut it. It’s the shock of cold that triggers an asthma attack as well as the dryness of the air.
Been there, done that!
