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 .
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
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 ...
The incidence of heat stroke is higher among men; however, the incidence of other heat illnesses is higher among women. [29] The incidence of other heat illnesses in women compared with men ranged from 1.30 to 2.89 per 1000 person-years versus 0.98 to 1.98 per 1000 person-years. [29]
At internal temperatures that high, the body’s vital organs can start to fail, not only because of the direct effect of the heat, but also because of the inflammation that the body produces in ...
Under those conditions, the body’s natural impulse is to dilate, or widen, the blood vessels so that more blood gets to the skin to expel as much internal heat as possible. The heart has to work ...
Increasing heat waves are one effect of climate change that affect human health: Illustration of urban heat exposure via a temperature distribution map: red shows warm areas, white shows hot areas. The effects of heatwaves tend to be more pronounced in urban areas because they are typically warmer than surrounding rural areas due to the urban ...
“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 ...
