“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 ...
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 .
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 ...
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]
With extreme heat gripping much of the Northern Hemisphere this week, authorities and public health experts have issued heat warnings to help keep people safe. Parts of China, India, the Middle ...
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]
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Medications for common conditions can increase patients' sensitivity to heat by impairing the body's response to high temperatures, including the ability to sweat and the rate of blood flow.
