Research from the University of Alberta finds intense cold-weather exercise makes it harder for the lungs to warm and humidify the air, causing airway lining to dry and, in some cases, become irreparably damaged. When temperatures plunge below –15 C, researchers recommend athletes decrease the intensity of outdoor exercise to protect their lungs.
