High altitude skiing allows skiers to take in the sights of snowy mountaintops and isolated wildlife. Unfortunately, this activity also carries the risk of altitude sickness, which occurs when the body is forced to rapidly adjust to high altitudes. Nose bleeds are one of the most common symptoms of altitude sickness.

If symptoms worsen or do not go away after several hours, consult a physician.
