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 ...
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, higher than the immediate environment [ 2] (from Greek ὅμοιος homoios "similar" and θέρμη thermē "heat").
Hibernation. Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – the so-called overwintering .
Radiative cooling. In the study of heat transfer, radiative cooling[ 1][ 2] is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation .
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
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]
