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.
In mountaineering the best practice is to avoid going onto the cornice by staying far enough back from the edge.ornices form by wind blowing snow over the leeward edge in successive layers. They can be very dangerous from traveling above and below them. A person or skier putting weight on top of a cornice can cause it to break off and collapse and causing a major fall, with no ground beneath, just snow or ice.
