Topic: Human Nose. Why do we get nosebleeds? I don’t know. Alright. I will explain. The medical term for a nosebleed is epistaxis. The most common epistaxis is anterior epistaxis where bleeding happens from the front part of our nostrils. Each of our nostrils has a mass of blood vessels called Kiesselbach’s plexus which is very close to the skin surface. Now, usually the mucus moisturizes the skin in our nose, thus protecting the blood vessels in it. Wow. Mucus is so useful. Yes. It is. However during winter, the air is dry. Hence, when we inhale this dry air, it draws moisture from the mucus which in turn leads to the drying of skin in our nose. Now, some people’s skin is very sensitive. If it dries, the skin and blood vessels in
it get easily damaged causing an anterior epistaxis or nosebleed.
