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.
About 240 people have died attempting to climb Mount Everest. Avalanches, rockslides, blizzards, falls, altitude sickness, freezing temperatures, exhaustion and combinations thereof have all proven fatal, particularly in the so-called âdeath zoneâ above 26,000 feet.
