Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps, heat rashes, and chronic kidney disease (CKD). [2] [3] Although heat exhaustion is less severe, heat stroke is a medical emergency and requires emergency treatment, which if not provided, can lead to death. [4]
Between 1999 and 2003, the US had a total of 3442 deaths from heat illness. Those who work outdoors are at particular risk for heat illness, though those who work in poorly-cooled spaces indoors are also at risk. Between 1992 and 2006, 423 workers died from heat illness in the US. [6] Exposure to environmental heat led to 37 work-related deaths.
Heat and cold stress occur when the temperature is significantly different from room temperature (68-74 degrees Fahrenheit). [30] When the body is exposed to heat stress, excess sweating can lead to a range of heat-related illnesses. [31] Excessive cold can lead to several cold-related illnesses such as hypothermia, frostbite, etc. [32]

Thermal work limit (TWL) is an index defined as the maximum sustainable metabolic rate that well-hydrated, acclimatized individuals can maintain in a specific thermal environment within a safe deep body core temperature (< 38.2 °C or 100.8 °F) and sweat rate (< 1.2 kg or 2.6 lb per hour). [1]
