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.
Fear nothing except fear itself. Still, there are some if's and but's to this golden rule. The following are some of the mishaps that we have faced during our 4 years of Everest attempts: Avalanches. Falling rocks. Crevasse falls. Other falls (including getting hit by falling climber) Severe exhaustion/dehydration.
