BRIDGEPORT, CA
BRIDGEPORT, Calif. (Feb. 23, 2026) A military medical student & cold-water immersion study volunteer, enrolled in Marine Corps Mountain Warfare Center’s Mountain Medicine Course, recites the 9-line Medical Evacuation request and re-answer his baseline questions, such as their current stress levels, hot or cold body temperature sensation & shivering levels following his10-minute cold-water immersion experience. Upon completing the questionnaire, subjects proceed to the active rewarming phase where they change into dry winter gear and do a series of exercises including squats, jumping jacks, running & arm circles. Through its cutting-edge cold water immersion studies, the Naval Health Research Center (NHRC) develops life-saving strategies that enable the warfighter to overcome the initial, lethal shock of entering frigid water. This vital research provides U.S. Naval, Marine Corps, and joint forces with the tools to maintain cognitive function and enhance survivability in the most extreme maritime environments.

BRIDGEPORT, CA
BRIDGEPORT, Calif. (Feb. 23, 2026) Military medical students, enrolled in Marine Corps Mountain Warfare Center’s Mountain Medicine course, participate in Naval Health Research Center’s (NHRC) cold-water immersion study. For the next 10 minutes these students will endure 34-degree water and below freezing air temperatures while their instructors watch and instruct them to do finger dexterity exercises; giving the students a chance to test their dexterity and cognitive response abilities in real time. In the final two minutes, students remove their masks & portable spirometer and answer a series of questions related to their current stress levels, body temperature and shivering. Through its cold-water immersion studies, NHRC develops life-saving strategies that enable the warfighter to overcome the initial, lethal shock of entering frigid water. This vital research provides U.S. Naval, Marine Corps, and joint forces with the tools to maintain cognitive function and enhance survivability in the most extreme maritime environments.

BRIDGEPORT, CA
BRIDGEPORT, Calif. (Feb. 23, 2026) Douglas Jones, principal investigator for Naval Health Research Center’s (NHRC) Environmental & Thermal Physiology team, discuss the ongoing cold-water immersion study with military personnel, ensuring the execution and prioritization of safety for the military participants. Through its cold-water immersion studies, NHRC develops life-saving strategies that enable the warfighter to overcome the initial, lethal shock of entering frigid water. This vital research provides U.S. Naval, Marine Corps, and joint forces with the tools to maintain cognitive function and enhance survivability in the most extreme maritime environments.

BRIDGEPORT, CA
BRIDGEPORT, Calif. (Feb. 23, 2026) Michael Sarmiento and Tony Duong, exercise physiologists with Naval Health Research Center’s (NHRC) Environmental & Thermal Physiology team, compile data collected from military medical students post cold-water immersion. Once the data has been compiled, analyzed and charted it will be used to build preliminary findings about the effects of cold-water shock response, dexterity & core body temperature. Through its cold-water immersion studies, NHRC develops life-saving strategies that enable the warfighter to overcome the initial, lethal shock of entering frigid water. This vital research provides U.S. Naval, Marine Corps, and joint forces with the tools to maintain cognitive function and enhance survivability in the most extreme maritime environments.

BRIDGEPORT, CA
BRIDGEPORT, Calif. (Feb. 23, 2026) Tony Duong, an exercise physiologist with Naval Health Research Center’s (NHRC) Environmental & Thermal Physiology research team, outfits a military medical student with a metabolic mask and portable spirometer prior to a cold-water immersion. The spirometer monitors breathing patterns, allowing for observation into the effects of cold-water shock response. The cold-water shock response is an involuntary and potentially life-threatening reaction to sudden exposure to water below 59°F; this response typically involves a sudden gasp, increased breathing and heart rate. Through its cold-water immersion studies, NHRC develops life-saving strategies that enable the warfighter to overcome the initial, lethal shock of entering frigid water. This vital research provides U.S. Naval, Marine Corps, and joint forces with the tools to maintain cognitive function and enhance survivability in the most extreme maritime environments.

BRIDGEPORT, CA
BRIDGEPORT, Calif. (Feb. 22, 2026) Rebecca McClintock, a research physiologist with Naval Health Research Center’s (NHRC) Environmental & Thermal Physiology team, meets with a military medical student in the Marine Corps Mountain Warfare Training Center lecture hall, to establish a baseline on his ability to recall a 9-line medical evacuation request and to record current levels of stress and anxiety prior to his cold-water immersion experience. These baseline results allow the researchers to build a clearer picture on the effects of the cold-water shock response on warfighters and analyze critical components that determine their ability to get back into the fight. Through its cold-water immersion studies, NHRC develops life-saving strategies that enable the warfighter to overcome the initial, lethal shock of entering frigid water. This vital research provides U.S. Naval, Marine Corps, and joint forces with the tools to maintain cognitive function and enhance survivability in the most extreme maritime environments.
