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] It can affect any or all anatomical systems. [2]
Heat stroke results in more than 600 deaths a year in the United States. [4] Rates increased between 1995 and 2015. [3] Purely exercise-induced heat stroke, though a medical emergency, tends to be self-limiting (the patient stops exercising from cramp or exhaustion) and fewer than 5% of cases are fatal.
Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system .
The overall effects of alcohol lead to a decrease in body temperature and a decreased ability to generate body heat in response to cold environments. [34] Alcohol is a common risk factor for death due to hypothermia. [ 33 ]
Unlike heat exhaustion, heat cramps and heat syncope do not have systemic effects. 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 pallor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of ...
On a recent tour underneath Chicago’s iconic skyline, Alessandro Rotta Loria, an assistant professor of civil and environmental engineering at Northwestern University, pointed out one of the ...
Heat stress causes illness but also may account for an increase in workplace accidents, and a decrease in worker productivity. [5] Worker injuries attributable to heat include those caused by: sweaty palms, fogged-up safety glasses, and dizziness. [2] Burns may also occur as a result of accidental contact with hot surfaces or steam.
It is a term adopted by an influential group of pharmaceutical executives and academic scientists to describe potentially fatal bleeding and swelling in the brain caused by drugs like Leqembi.
