Heat stress is a major concern for military personnel and for first responders such as firefighters, and hazardous materials personnel. Exposure to heat, high energy expenditure and the use of "bunker gear" protective clothing can result in significant and rapid fluid and electrolyte loss.
Lack of adequate hydration impairs the body's ability to maintain a stable core temperature, and decreases strength, endurance, and blood volume. Core body temperature rises 0.15-0.20°C for each 1% loss in body mass. Furthermore, for each 1% loss in body mass, heart rate increases by 3-5 beats/min. Progressive acute dehydration can lead to a significant increase in cardiovascular strain.
Local, regional, state and federal entities concerned with the health, safety and productivity of military and first responder personnel have long been interested in the development and implementation of methods and tools to diagnose and treat the signs and symptoms of heat stress. As a result, Cantimer has already been awarded over $2 million in non-dilutive funding to support research projects related to hydration measurement and monitoring for military and first responder personnel.
