If the ,clothing, does not properly ,transfer, the metabolic ,heat, and sweat-vapor, it results in a rapid increase of core body temperature (T core) from a normal 37°C. Because their work places them in ambient environments where this situation is likely to transpire, a great amount of ,heat, stress (cardiovascular and thermoregulatory strains) occurs to firefighters [28-30,164-166].
