This is why Everest climbers typically make several trips up and down the mountain to increasingly high elevation camps to acclimate their bodies to high altitude conditions. Other risks to Everest climbers include frostbite and hypothermia from the extreme temperatures, thrombosis or embolisms caused by thickening of blood in response to high altitude, extreme sunburn, and broken bones from falls.
Summary. 1  Mountain climbers are at risk of developing altitude sickness. 2  Altitude sickness is caused by ascending too rapidly, which doesn't allow the body enough time to adjust to reduced oxygen and changes in air pressure. 3  Symptoms include headache, vomiting, insomnia and reduced performance and coordination.
