What tents do you use on the plateau?
A lot of people say that oxygen is thin at high altitudes, but it's not correct to say that, because at high altitudes, the air is the same. The reason why people feel the lack of oxygen is because the higher the altitude, the thinner the air and the lower the air pressure. The result is the reduction of oxygen partial pressure, ordinary people, maybe even sitting or standing will feel breathing and heartbeat, showing symptoms of hypoxia. If you live in this environment for a long time, your body will gradually adapt to the changes in the chemical composition of the blood and produce more red blood cells to carry more oxygen. Usually at least two week to change, if not to three weeks so that there will be significant changes, then back to low altitude, oxygen uptake will improve the ability of the human body, is also a corresponding increase in VO2max.
On the choice of sleeping bags and tents, it is recommended that you bring a down sleeping bag with 15 degrees below zero and a double deck rain curtain. Plateau camping, usually wind larger, especially the Qinghai Tibet railway, northern Tibet Grassland, Ali and other places, winter evening outdoor temperature below 20 degrees below. If there is no indoor fire, but also to minus 5 degrees, like the ordinary sleeping bag and tent and do not play any role.
