One option: 1 function of the nose is to warm cold air before it moves to the lungs. Capillaries in the nose dilate to bring warm blood to the nares. As these tissues fill with blood the nose becomes congested. Any air that makes it to the lungs that is still cold can trigger release of histamines & cause bronchospasm. Recommend wearing a scarf on other clothing article that can be placed over nose/ mouth.
