Normal human body temperature ( normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [ 8][ 9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation ...
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.
Human thermoregulation. 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 ...
Normal body temperatures vary depending on many factors, including age, sex, time of day, ambient temperature, activity level, and more. [ 37 ] [ 38 ] Normal daily temperature variation has been described as 0.5 °C (0.9 °F).
The zeroth law of thermodynamics allows this definition to be used to measure the absolute or thermodynamic temperature of an arbitrary body of interest, by making the other heat reservoir have the same temperature as the body of interest. Kelvin's original work postulating absolute temperature was published in 1848.
Algor mortis (from Latin algor 'coldness' and mortis 'of death'), the third stage of death, is the change in body temperature post mortem, until the ambient temperature is matched. This is generally a steady decline, although if the ambient temperature is above the body temperature (such as in a hot desert ), the change in temperature will be ...
Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [ 4] along with red skin, headache, dizziness, and confusion. [ 2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [ 5]
Thermogenesis. v. t. e. The group that includes mammals and birds, both "warm-blooded" homeothermic animals (in red) is polyphyletic. Homeothermy, homothermy or homoiothermy[ 1] is thermoregulation that maintains a stable internal body temperature regardless of external influence. This internal body temperature is often, though not necessarily ...
