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.
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.
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 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 illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.

Extreme heat increases the chances of birth complications, said Patel, while Halsey noted that pregnant people are more susceptible to heat stroke. A construction worker pictured drinking water on ...
There are two types of heat the body is adapted to, humid heat and dry heat, but the body adapts to both in similar ways. Humid heat is characterized by warmer temperatures with a high amount of water vapor in the air, while dry heat is characterized by warmer temperatures with little to no vapor, such as desert conditions.
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 ...
