Mountainous terrainLow oxygen levels, variations in partial pressure, and changes in lung capacity are stress factors associated with high altitude. This section provides information and awareness on policies, reports and guidelines for performing well in high altitude.

A Soldier’s Guide to Staying Healthy at High Elevations [PDF]
The U.S. Army Public Health Command and USARIEM developed this guide to provide Warfighters with helpful information on the threats associated with operations in high altitudes and use of personal protective measures to minimize disease and non-battle injuries.
Altitude Acclimatization Guide [PDF]
This technical document provides guidelines to decrease susceptibility of Warfighters to altitude illness and optimize physical and cognitive performance for successful missions.
Altitude Effects on the Human Body
Above 1200m/4000ft, altitude can have serious effects on performance and health. The United States Army Public Health Command offers information that can help you recognize—and avoid—the effects of altitude.
Altitude Illness and Environmental Threats
This United States Army Public Health Command web page has information about how to cope with altitude illness, high-altitude cold injuries, sunburn at altitude, snow blindness, and other environmental threats associated with deployment and training at altitudes above 1200m/4000ft.
EPO for altitude acclimitization
A look at the use of exogenous erythropoietin (EPO) for faster altitude acclimatization.
High-Altitude Training Masks
Commercial devices are available that purportedly help a person acclimatize to high altitude while they are still training at normal atmospheric pressure, but their effectiveness is questionable.
How can Warfighters prevent and manage altitude illness?
It is commonly believed that physical fitness can prevent acute mountain sickness, but this is a myth.
Intermittent Normobaric-Hypoxia Exposure Conditioning Program
Commercially-available normobaric hypoxic devices simulate altitude. Are they useful for improving health and performance at high altitudes?
Is Erythropoietin (EPO) Useful For High Altitude Acclimatization?
This scientific summary is provided courtesy of U.S. Army Research Institute of Environmental Medicine (USARIEM).
Short-Duration Altitude Acclimatization
The effects of short-term altitude acclimatization are varied and include both cognitive and psychomotor components.
Sun Safety
Although normally associated with hot environments, sun exposure is also a serious issue at high altitudes. The United States Army Public Health Command has a web page that addresses sun safety regardless of the temperature or altitude.
TB 505: Altitude Acclimatization and Illness Management [PDF]
This U.S. Army Technical Bulletin (TB 505) is related to hypobaric hypoxia, an environmental stress resulting from ascent to progressively higher terrestrial elevation or altitude.
Traumatic Brain Injury and the Effects of Altitude [PDF]
The Defense Centers of Excellence for Psychological Health & Traumatic Brain Injury provide an analysis of the scientific literature that includes a discussion of risk factors, military concerns, and operational constraints, as well as clinical and research considerations for traumatic brain injury and altitude.‬‬‬‬‬‬‬‬
