Two Days of Staging as Effective as Four for High Altitude Climbs




New findings could help recreational climbers, military get to high altitudes quickly and safely

Afghanistan’s geography  is dominated by a collection of craggy peaks, the highest—a mountain known as Noshaq—has been measured to 7,492 meters. Consequently, the soldiers on duty in this mountainous terrain must often ascend to great heights as part of their duty. However, quick climbs without aadapting to altitude can lead to a condition called acute mountain sickness (AMS), marked by headache, fatigue, gastrointestinal distress, nausea, and insomnia.

Conventional knowledge suggests that to avoid AMS, climbers need to “stage,” or set up camp, at a lower altitude for four days when summiting peaks as high as 4300 meters. However, with this being impractical in a combat environment, military researchers set out to test whether this goal could be accomplished more quickly—in half the time.
