Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. [1]
Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [4] along with red skin, headache, dizziness, and confusion. [2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...

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]
Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness. Heat stroke is more likely than heat exhaustion to cause palor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of spatial awareness, loss of bodily movement control, seizures, etc.).
