How long should soldiers stay at a moderate altitude during a staged ascent?

Staying at a moderate altitude during a staged ascent for at least three days serves a crucial purpose in helping soldiers acclimatize to lower oxygen levels encountered in higher altitudes. This period allows the body sufficient time to adapt to the reduced atmospheric pressure and decreased oxygen availability, which can help prevent altitude sickness and ensure that soldiers can perform at their best.

During this acclimatization phase, physiological changes occur, such as increased red blood cell production and improved oxygen delivery to tissues, facilitating a smoother transition to even higher altitudes if necessary. Generally, longer stays at moderate altitudes can further enhance these adaptations, but three days is typically considered the minimum necessary time frame for effective acclimatization. This strategy is crucial in military operations where altitude can impact performance and safety.
