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.
Initial experiments by Leroi et al., the first scientists to address this problem, tested only the beneficial acclimation hypothesis and not the subsequent hypotheses developed by Huey et al. [2] Colonies of E. coli were acclimated for seven generations in two different temperature conditions: 32 °C and 41.5 °C. Colonies were then competed ...
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 ...

Satisfaction with the thermal environment is important because thermal conditions are potentially life-threatening for humans if the core body temperature reaches conditions of hyperthermia, above 37.5–38.3 °C (99.5–100.9 °F), [11] [12] or hypothermia, below 35.0 °C (95.0 °F). [13]
An early morning temperature higher than 37.3 °C (99.1 °F) or a late afternoon temperature higher than 37.7 °C (99.9 °F) is normally considered a fever, assuming that the temperature is elevated due to a change in the hypothalamus's setpoint. [15]
“We do go back to Silo 17” in Season 3, he noted. “And remember, they’ve got a very big power issue there, so they don’t have a lot of light.” But when Silo does shine in Season 3 ...
