A member asked:

I ve dry nose,especially in winter[below 40 humidity], i ve to use humidifier to breath well,what may be the cause while others can breath without it?

A doctor has provided 1 answer

Not uncommon: Many have either a dry nose (with nose bleeds) or dry/soar throat after sleeping the night in poor humidity. The oral/nasal airway adds water to the air as it enters the lungs.Humidity needs to be near 100% at the air exchange point in the lungs or you get tissue injury.Nasal allergies, septal deviation and or membrane swelling aggravates the process.It is a natural event for many.
