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 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 .
Heatstrokes can cause severe symptoms, including changes in mental status, coma and seizures.A milder form of heat-related illness, known as heat exhaustion, can cause headache, nausea or dizziness.
“The higher the humidity, the lower temperatures you need for extreme heat,” Linden said. High body temperatures can lead to damage to the brain and other vital organs, the CDC says. They can ...
Air pollution can be a high risk for certain groups, including children under 18, adults over 65, people with chronic heart or lung disease, pregnant women and people with diabetes, according to ...
Treatment of heat stroke involves rapid mechanical cooling along with standard resuscitation measures. [22] The body temperature must be lowered quickly via conduction, convection, or evaporation. [4] During cooling, the body temperature should be lowered to less than 39 degrees Celsius, ideally less than 38-38.5 degrees Celsius. [5]
A whopping 6.3 billion people worldwide experienced at least 31 days of extreme heat since mid-2023. As the climate crisis drives more extreme and frequent heatwaves in the US and around the world ...
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 palor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of ...
