Elevated core body temperature is a problem for many, including athletes,
industrial workers, miners and soldiers. Emergency medical responders
and physicians are often overwhelmed by heat stress incidents. Anyone
regularly subjected to exertion in sweltering conditions knows what heat
can do to performance. As the temperature of the body’s core organs
(heart, lungs, liver, kidneys, and brain) rise, fatigue sets in and strength,
endurance and cognitive functions deteriorate rapidly.
