Stay Warm
Staying warm is one of the most effective ways to treat mucus. In the body’s respiratory system, mucus is produced by special cells called goblet cells, which are located in the lining of the nasal passages and sinuses, as well as the trachea (the main passage for air to enter and exit your lungs). Each cell produces a small amount of mucus every minute. When these cells are exposed to cold temperatures, they produce more mucus than usual when exposed to cold temperatures.
Additionally, when exposed to cold temperatures over a long period, these cells stop producing as much mucus as usual. As a result, you may feel as if your nasal passages and sinuses are dry in a cold environment, like an air-conditioned room or sitting outside on a winter day. In reality, however, this is just an effect of your body producing more mucus than usual—your nasal passages are full of extra mucus.
The same effect can be observed when you feel like your throat is dry. It may be coated in mucous membranes produced because it was exposed to cold temperatures for too long.
