Research Institute of Environmental Medicine


USARIEM is internationally recognized as the DoD's premier laboratory for Warfighter health and performance research and focuses on environmental medicine, physiology, physical and cognitive performance, and nutrition research. Military guidance has been published for operations in heat, cold, and high-altitude environments and nutrition for health and performance.

The Institute is organized into four divisions: Military Nutrition, Military Performance, Thermal and Mountain Medicine, and Research Support. By leveraging its unique capabilities and facilities with industry, academia, and the government, USARIEM produces a variety of important products, including performance optimization doctrine, preventive medicine and planning doctrine, materiel development support, physiological monitoring strategies and predictive algorithms, and Health Hazard Assessments. USARIEM personnel were consultants on the establishment of the Olympic Training Center in Colorado Springs, Colorado.

The U.S. Coast Guard mandated the use of USARIEM's Probability of Survival Decision Aid (PSDA) predictive model as part of the U.S. National Search and Rescue Supplement to the International Aeronautical and Maritime Search and Rescue Manual, COMDTINST M16130 (Series). The PSDA will be used for all cases involving persons in the water and where persons are at risk of hypothermia. This model replaces the Cold Exposure Survival Model (CESM).


USARIEM's mission is to optimize Warfighter health and performance through medical research.
