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 ...
Origins of heat and cold adaptations can be explained by climatic adaptation. [16] [17] Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (70 °F). [5] [disputed – discuss] The body controls its temperature through the hypothalamus.
One person was purported to survive 7 days in the desert, 6 of these without water, without suffering heat stroke as the temperature reached no higher than 103.2 °F (39.6 °C) during his ordeal. [9] However, he had reached the third stage of dehydration, which is 80-90% fatal; this likely represents an upper limit of survival at high temperatures.
