About this Unit
The U.S. Army Research Institute of Environmental Medicine (USARIEM) was established in 1961 at Natick, Massachusetts, as a premier biomedical research laboratory for the United States Army. Its mission is to conduct research on environmental medicine, physiology, and nutrition to optimize the health and performance of military personnel operating in diverse and challenging conditions. Over the decades, USARIEM has contributed vital knowledge and innovations in areas such as heat and cold stress, altitude adaptation, hydration, and physical readiness. The institute’s research has led to the development of protective equipment, rations, and guidelines that enhance the safety and effectiveness of soldiers worldwide.
Historical Facts
•
Origins in World War II: The U.S. Army Research Institute of Environmental Medicine (USARIEM) traces its roots to World War II, when the military recognized the need for scientific research on soldier health in extreme environments.
•
Established in 1961: USARIEM was officially established in 1961 at Natick, Massachusetts, and has been a leader in biomedical research for warfighter health and performance ever since.
•
Heat Stress Research: USARIEM developed the Wet Bulb Globe Temperature (WBGT) index, now used worldwide to measure heat stress and prevent heat casualties in military and civilian settings.
•
Cold Weather Studies: The institute has conducted pivotal studies on frostbite, hypothermia, and cold weather clothing, directly influencing U.S. Army gear and survival protocols.
•
Altitude Acclimatization: USARIEM's research on high-altitude physiology has been critical in preparing soldiers for deployments in mountainous and high-altitude regions like Afghanistan.
•
Nutrition and Rations: The institute has played a key role in developing and improving military rations, including the famous Meals Ready-to-Eat (MREs), optimizing nutrition for performance.
•
Female Soldier Research: USARIEM has led studies on the unique physiological needs and challenges faced by female soldiers, influencing training and equipment policy.
•
Physical Fitness Standards: Their research underpins many of the Army’s physical fitness standards, such as the development of the Army Physical Fitness Test (APFT) and the new Army Combat Fitness Test (ACFT).
•
COVID-19 Response: During the COVID-19 pandemic, USARIEM contributed expertise in respiratory protection, mask fit, and operational guidelines to help protect soldiers.
•
International Collaboration: USARIEM scientists frequently collaborate with NATO allies and international partners on environmental medicine research, sharing knowledge that benefits militaries worldwide.
