When the body seeks to rid itself of excess heat, the hypothalamus triggers a heart rate increase and vasodilation (expansion of blood vessels) to increase blood flow in the outer layers of the skin, transferring heat much like the coolant flowing through a radiator. In contrast, when the body detects a drop in blood temperature it reduces blood flow in the outer layers of skin to trap heat within the body, and can even trigger unintended muscle movement - shivering as a way to generate metabolic heat.
In either case metabolic fuel, electrolytes and fluids - the same resources needed for peak physical performance - are redirected from the task at hand to maintaining a stable body temperature.
RiteTemp Athletics products work on an extremely simple principle - they either absorb heat from the body, or deliver heat to the body as needed to maintain an optimal body temperature. By reducing the body's burden of heat management athletes, game officials and even fans benefit from increased stamina in warm or cold environments. Competitors can keep going longer, umpires and referees can stay sharp longer, and sports fans can comfortably enjoy the competition longer.
