Does Temperature Change Cause Runny Nose?
Many people have experienced a runny nose when exposed to a sudden change in temperature. This phenomenon is often referred to as "chilly-induced rhinorrhea." It occurs when the outer layer of the nasal passages cools down and causes the blood vessels in the nose to expand. This leads to increased blood flow, swelling, and nasal secretions.
Rhinorrhea is the medical term for a runny nose and can be caused by a wide variety of factors, including allergies, infections, and even emotional stress. However, the most common cause is a sudden change in temperature.
When exposed to a sudden drop in temperature, the body responds by sending a message to the brain to restrict blood flow to the face and nose area. This causes the blood vessels to narrow and leads to the production of excess mucus. This mucus then runs out of the nose, leading to a runny nose.
The same phenomenon also occurs when exposed to a sudden rise in temperature. When exposed to high temperatures, the body sends a message to the brain to expand the blood vessels in the face and nose area. This leads to increased blood flow, swelling, and increased mucus production, resulting in a runny nose.
There are several ways to minimize the effects of chilly-induced rhinorrhea. Wearing a scarf or hat can help to keep the head and nose warm, which helps to reduce the risk of a runny nose. It is also important to drink plenty of fluids, as this can help to thin out the mucus and reduce the risk of a runny nose. Finally, avoiding sudden changes in temperature can also help to reduce the risk of a runny nose.
