EXERCISING IN HEAT 

External heat stress causes poor thermoregulation. Body temperatures increase during exercise due to an imbalance of internal heat production and heat dissipation at the skin surface. Heat production is a by-product of elevated rates of metabolism and supporting muscle contractions. Heath production can also increase form convention, radiation, and dissipating through the evaporation of sweat. Wind levels, humidity and air temperature influence thermoregulation by convection, radiation and evaporation and weather specific clothing can protect the skin and body from weather related conditions (Casa et al., 2015).
