This metabolic ,heat, increases firefighters’ normal core body temperature (37°C) if the ,heat, dissipation to the environment is too low [118]. If the core temperature variation of 0.1-0.5°C is sensed by firefighters’ central and/or peripheral nervous receptors, these receptors send the information to the hypothalamus, which will induce thermoregulatory measures to fight the ,heat, [157].

Protective clothing, protects wearers from hostile environments, including extremes ,of heat, and cold. Whilst some types of ,protective clothing, may be designed primarily for non-,thermal, hazards (e.g. biological hazards), a key challenge in all ,protective clothing, remains wearer comfort and the management ,of thermal, stress (i.e. excessive ,heat, or cold).

Analytical methods (for example ISO 7933) for the assessment of the ,thermal, strain caused by human exposure to hot environments require a ,mathematical, quantification of the ,thermal, properties of ,clothing,. These ,effects, are usually considered in terms of 'dry' ,thermal, insulation and vapour resistance.
