WebbIn response to environmental temperatures ranging 15-45–C and to exercise at levels of 500 and 1,000 kgm/min, the selected glove temperature ranged 20-40–C. The preferred glove temperature (a) depended strongly on internal body temperature, (b) was affected to a lesser extent by mean skin temperature, and (c) was not affected by exercise alone. 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.

WebbNormally, the hypothalamic thermoregulatory center maintains the internal temperature between 37 ° and 38 ° C. Fever results when something raises the hypothalamic set point, triggering vasoconstriction and shunting of blood from the periphery to decrease heat loss; sometimes shivering, which increases heat production, is induced. login webmail hispeedThe 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, and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
