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.
Everest is a mountain of extremes, said Jon Kedrowski, a geographer and climber. Kedrowski summited Mount Everest in 2012, another brutal year on the mountain, when overcrowding combined with a dangerous weather pattern to strand climbers in the death zone below the summit. Ten people died.
