Altitudinal acclimatization

Altitudinal acclimatization is the process by which the body adjusts to higher elevations where oxygen levels are lower. As you ascend, your body responds by increasing breathing rate, producing more red blood cells to carry oxygen, and improving how efficiently your tissues use oxygen. These changes typically occur over days to weeks, helping you perform better and avoid altitude sickness. The process varies among individuals and depends on how quickly and gradually you change elevation, allowing your body to adapt safely to the reduced oxygen availability at higher altitudes.
