Why do the nose bleed at higher altitudes?
Answers
Explanation:
Sometimes when we climb up the hill, our NOSE starts bleeding at high altitudes. This occurs especially in WINTER season. There are so many reasons for NOSE BLEEDS. But, bleeding of NOSE at high altitudes and Cold temperatures are because of surrounding WEATHER CONDITIONS. Lets know what this changing weather does to our Body.
Our NOSE is very RICH in BLOOD VESSELS. The Front part of our NOSE is where 5 BLOOD ARTERIES join together. This area is called the Kiesselbach's Triangle or Little's Area. Nose Bleed is the LOSS of Blood from the TISSUE lining the NOSE.
Dry Air moving through the NOSE dries NASAL MEMBRANES lining inside the Nose, forming crust. These Crust BLEEDS when irritated by Running, Picking or Blowing the Nose. The Water Vapour present in the AIR acts as a LUBRICANT for the movement of Air through our NOSE. Absence of it increases FRICTION and irritates our Nasal Membranes.

The Medical Name for Nose Bleeding is EPISTAXIS. This Bleeding can be avoided by handling our NOSE softly.

Explanation:
Hot climates with low humidity or changes from bitter cold to warm, dry climates can cause drying and cracking inside the nose, which canlead to a nosebleed. High altitude - asaltitude increases, the availability of oxygen decreases, making the air thinner and drier. The dryness cancause the nose to bleed.
