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.
The answer likely differs for each climber, and studies suggest that people who take risks tend to perceive them differently from people who avoid the same behaviors. But for adventurers who are drawn to Everest, the mountain's top is a lifelong dream that inspires intense preparation and a deep sense of reverence.
