why does our nostrils sometimes breathe “too well” (air goes in too easily) that it burns everytime you inhale?

In: Biology

Your nostrils should be a wet environment – they’re full of tiny hairs and mucus. This works as an air filter; tiny particles of dust, smoke, bacteria, and other impurities stick to the mucusy hair and don’t go into your sinuses or lungs. It also helps warm and moisturize the air before it reaches those warm damp environments.

But when the air is very dry, your nose can be too. Mucus dries up and your nose gets very clear. As a result, the air flowing into your sinuses and lungs is dry, cold, and dirty, any one of which can be painful.
