Your NOSE bleeds at Higher Altitudes - WHY??

             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.


             Here are the changes in our Surrounding that occurs at HIGH ALTITUDES.

• The Atmospheric Pressure goes down.
• The Temperature decreases.
• Water Vapour content is less.
• The Relative HUMIDITY decreases because of fall in water vapour content.

              What bothers our body is the RELATIVE HUMIDITY. Relative Humidity is simply the amount of Water Vapour present in the AIR. When humidity reduces, the AIR becomes DRY.  This Dry air is not good for our NOSE.

               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.
