Defining High Altequde andIts Environmental Thresholds

High altexte regions, typically defined as areas above 2,500 meters (8,200 feet) in elevation, item some of te most demanding environments for human habitation on Earth. At these elevations, thee partial pressure of oksygen drops significatiantly, creating a state of chronic hypobaric hypoxia. Envimental physiologists often stratify these zone into viories: moderate algede (1,500- 2,500 m), high altede (2,500500 m), very higne altone (2,50050m), altone (3,5000m), extredane (3,5000 m), extravedande (1,50 m).
