BRIDGEPORT, Calif. (Feb. 23, 2026) Nick Stone (left), a research assistant with Naval Health Research Center’s (NHRC) Environmental & Thermal Physiology research team, outfits a military medical student with heart rate chest straps (Polar) and core (BodyCAP) and skin temperature (iButton) measurement devices that the researchers team use to record critical data segments to analyze post immersion. The blue data loggers are linked to a core temperature pill that allows continuous field core body temperature monitoring, while the chest straps continuously track 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.
