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.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
Record-setting heat waves have gripped the U.S. only weeks into summer, and at least 38 people are suspected to have died from heat-related issues so far this summer.

'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 ...
On Wednesday, there were 21 heat-related deaths at Beni Mellal’s main hospital as temperatures spiked to 48.3 degrees (118.9 degrees Fahrenheit) in the region of 575,000 people, most lacking air ...
A 2022 study on the effect of heat on young people found that the critical wet-bulb temperature at which heat stress can no longer be compensated, T wb,crit, in young, healthy adults performing tasks at modest metabolic rates mimicking basic activities of daily life was much lower than the 35 °C (95 °F) usually assumed, at about 30.55 °C (86 ...
But that range is lower than the actual temperature in Death Valley, California. A persistent and deadly heat wave is still baking parts of the country. Almost a third of the country, stretching ...
