The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F). [1] Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate.
The inscription '1.5 °' at Neustädter Elbufer in Dresden for adhering to the 1.5-degree target by Fridays for Future (2022). The 1.5-degree target (also known as the 1.5-degree limit) is the climate goal of limiting the man-made global temperature increase caused by the greenhouse effect to 1.5 °C on a 20-year average, calculated from the beginning of industrialization to the year 2100.

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 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
Typical values for the viscosity of normal human plasma at 37 °C is 1.4 mN·s/m 2. [3] The viscosity of normal plasma varies with temperature in the same way as does that of its solvent water [4];a 3°C change in temperature in the physiological range (36.5°C to 39.5°C)reduces plasma viscosity by about 10%. [5]
'Wet-bulb' temperature records show that deadly thresholds for heat and humidity are arriving faster than anticipated. Global warming now pushing heat into territory humans cannot tolerate Skip to ...
Heat waves have become more frequent, and more intense over land, across almost every area on Earth since the 1950s, the increase in frequency and duration being caused by climate change. [3]: 8–10 [4] Heat waves form when a high-pressure area in the upper atmosphere strengthens and remains over a region for several days up to several weeks. [5]
A new study finds that normal human body temperatures have dropped since the late 1800s. So what you think is normal may actually be a fever.
