President's Prescription: Cold Weather, Runny Nose

Posted: Updated:

Fall weather is here and with the cold temperatures the human body reacts.

Your nose is for much more than just smelling. It produces more than a liter of mucus a day. In cold climates, it actually increases the amount of secretion of the mucus glands. Many believe that runny noses or the amount of mucus that's produced is a sign that they have been exposed to a virus that could cause a cold. But in reality, it's a normal physiological response, and it results from the cold, often dry cold weather.

Your nose is a defense mechanism. The mucous membranes lining the nose produce the mucus to rinse out viruses, bacteria and dust before they reach the lungs. The fluid moistens the air you breathe to help protect your throat. So in cold air, your nose is working overtime. The extra fluid has to run out…. either out your nose… or down the back of your throat.

If you catch a cold, don't blame the cold weather. The only thing that affects you getting a cold is the germ itself, and you are less likely to come in contact the germ in colder weather. For the Texas Tech University Health Sciences Center, I'm Dr. Tedd Mitchell, and this is the President's Prescription.
