In this episode Dr Ross Di Corleto, Principal Consultant and Director of Monitor Consulting Services joins host Mark Reggers for the first of a two-part series on heat stress & strain in the workplace. Heat stress and heat strain are two different terms that are often incorrectly interchanged, using one phrase for the other. Heat stress refers to the net heat load to which a worker is exposed through physical exertion, environmental factors, and clothing worn. Heat strain is the body’s physiological response to heat stress, resulting in sweating, increased heart rate and elevated core temperature. Heat stress leads to heat strain which can give rise to heat-related illnesses or death if not managed correctly.
