In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. Hyperthermia requires an elevation from the temperature that would otherwise be expected.

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.

Webb8 mars 2024 · However, the major effect at the central level is exerted by progesterone. This hormone shifts the thermoregulatory set point(s) in the hypothalamus towards higher temperatures. This results in a higher Tc, as it can be observed in the luteal phase of the human ovarian cycle, with very high levels of circulating progesterone (6, 18) .
