It's just the cold air , the air has a sort of drying effect on the airways. So your body responds by producing mucus to reduce water loss. Also the cold air irritates the muscles in the airways causing them to contract , therefore it is harder to breathe.

Getting really snotty, especially in a cold headwind. Sometimes I even choke on my mucus. Is this because of lack of water intake, or is it generally due to poor fitness?
