There is no central heating or air conditioning, not even insulated walls to shield a climber from the elements. Protective clothing To protect their bodies from the cold, climbers dress in layers. The layers draw sweat from their skin, provide insulation from the subzero temperatures and offer a bit of a windbreak against the cold. Eating and drinking as much as possible also helps. The body burns a lot of calories to stay warm so the extra calories and fluids keep circulation flowing and prevent the climbers from getting dehydrated.
Climbers watch for snow with sophisticated weather-tracking forecasts.
The experienced ones also use the eyes of veteran climbers to scan the horizon in search of upcoming problems. Of course, the key is to stay put and burrow in if it looks like a snowstorm is on its way. It's not only the storm that can be dangerous. The powerful rays of the sun that bounce off the snow can quickly cause blindness, so the climbers use glacier goggles. For the wind, climbers can't do much but hold on, reinforcing their tents and supplies as much as possible by anchoring them to the ice or to debris, such as used oxygen containers, around camp.
