I have asthma and yes, the trick is to get on the inhaled steroids like Advair, Qvar or the like. Keep the rescue inhaler (albuterol or combivent eg) close at hand. In cold weather, get a Buff rag for cool temps and something like a knit scarf or a Shemagh for cold temps to breath through. Think cotton and not felt like a Baclava. Those Baclavas are nasty as they get wet from your breath and stay soggy and cold. Yuck! Cover your mouth and breath warm air in the winter.
