An altitude chamber is a controlled environment designed to simulate high-altitude conditions. It allows individuals to experience reduced oxygen levels and lower air pressure, similar to what one might encounter at high elevations. This is useful for training athletes, preparing climbers for expeditions, or studying the effects of altitude on the human body. These chambers can be used for various purposes, including acclimatization for mountaineers and athletes who want to enhance their performance. They are also valuable in medical research, helping scientists understand conditions like altitude sickness and how the body adapts to changes in oxygen availability.
