Analysis of Heat Exposure on Health and Socioeconomic Impact

by Jasmine Kaur

One big factor of climate change that is reducing human performance and work capacity is heat exposure. Currently, in hot areas, 10% of daylight hours are too hot for work to be performed and by 2085, the loss of productivity working hours will have increased to 30-40%. The hot areas are Africa, Asia, Latin America, and at moderate risk are southeast and southwest United States. In these hot atmospheres the heat transfer of the intrabody to the external environment and away from the body is limited. The influence of heat exposure is causing the core body temperature to rise that leads to serious physiological risks. Mainly affected are the cardiovascular system with limitations of blood flow, increased heart rate, and conspicuous sweating. As climate change progresses the incidences of occupational health problems will rise, and labor productivity and work capacity will fall. Continue reading
