"Heat stress" is the "net [overall] heat load to which a worker may be exposed from the combined contributions of metabolic heat, environmental factors (i.e., air temperature, humidity, air movement, and radiant heat), and clothing requirements. The most effective way to reduce the negative impacts of an extreme heat event is to develop a comprehensive heat response plan that combines individual strategies into an integrated approach. To maintain this temperature without the help of warming or cooling devices, the surrounding environment needs to be at about 82F (28C). Convective heat exchange increases with increasing air speed and increased differences between air and skin temperature. Vasoconstriction shrinkingand vasodilation expansionof blood vessels to the skin can alter an organism's exchange of heat with the environment. The first effects relate to how you feel.
