Answer 2

Answer:

Mountain climbers often get nosebleeds at high altitudes because as the amount of oxygen in the air decreases and the air becomes drier, blood vessels inside your nose can crack and bleed.

To stop it :

         The low humidity dries the membranes of the nose, making them brittle and frequently causing nosebleeds. Dehydration and head colds may cause them as well. Avoid colds, stay hydrated and use a humidifier. If a nosebleed does occur, the most effective way to stop it is to pinch the nose together for 5 minutes.
