Cold temperatures outside present special problems for those with asthma. More time indoors usually means greater exposure to some of the most common asthma triggers, such as dust, animal dander, and seasonal triggers like fireplace ash. The cold outdoor air is also a known asthma trigger for many, so now is the time to tighten up your control. Take your medications exactly as prescribed, no backsliding! Wash your hands often, and wear a scarf over your mouth if you’re going to be outdoors (this helps warm the air going into your lungs). Do everything you can to prevent an asthma episode, as a trip to the ER is no way to spend the holidays.
