Question

in high altitude mountain areas nose of certain people starts bleding why

Answer 1

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.

thank you

Answer 2

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