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 higher you climb the less oxygen there is.  At the summit of Mount Everest there is approximately 33% of the  oxygen that is available at sea level. That is why climbersâ¦ use  bottled oxygen on Mount Everest and other high altitude mountains  to help them breathe more easily.
