Why does the nose run in cold air?
During the winter, when traveling in cold air, water often starts flowing from the nose, which increases the cold and confusion, but why does this happen?
In medical parlance, this process is called ‘cold undeveloped rhinitis’ and 50 to 90% of people suffer from this condition. It is more common in people with asthma, fever and eczema.
One of the many functions of our nose is to keep the air entering our lungs warm and moist so that they do not reach the lungs and cause inflammation and discomfort to their cells.
Even if it is very cold outside, the temperature of the air entering the nose is up to 26 degrees Celsius, which sometimes rises to 30 degrees Celsius, but in each case the humidity inside the nose is 100%. No matter how cold we breathe.
This shows that one of the functions of the nose is to ensure that the air reaching the lungs is warm and moist. Now, in cold and dry weather, the nerves inside the nose become active due to the cold air, the news of which reaches the brain. In response, the brain increases blood circulation to the nose and the nerves and veins inside the nose begin to warm up.
On the other hand, due to dryness and dryness, the cells inside the nose secrete fluid so that moisture can be added to the inhaled air. In the same way, the body’s immune system stimulates the nasal cells and thus begins to discharge water from the nose. It is estimated that our nose secretes 300 to 400 milliliters of water to function better.
During this time the blood flow inside the nose also increases. If this does not happen, it can lead to respiratory distress and sneezing.
