Have you ever wondered why our noses start running when we are outside in the cold weather? There’s a scientific explanation for it!
When we breathe chilly air, our noses make the air warm and add moisture to it on its way to our lungs.
The cold, dry air irritates the nasal lining, which leads to nasal glands producing more mucus. This is to keep the lining moist.
This can cause the nose to be runny as the excess mucus drips from the nostrils. To reduce this, you can wear a scarf as it warms the air before it enters your nose.
