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).
Most have a normal body temperature set point that falls within the range of 36.0 to 37.5 °C (96.8 to 99.5 °F). [13] The main reason for checking body temperature is to solicit any signs of systemic infection or inflammation in the presence of a fever. Fever is considered temperature of 37.8 °C (100.0 °F) or above. [13]
Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

When you're a small child, you learn that a square has four sides. When you get a little older, you learn that there are 50 states and that pi is roughly equal to 3.14. And at some point when you ...
Until the body temperature is raised to near-normal levels: Types: Primary hypothermia: caused by exposure to a cold environment; Secondary hypothermia: caused by an underlying pathology that prevents the body from generating enough core heat. Causes: Mainly exposure to cold weather and cold water immersion: Risk factors
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). [7]: 4012 A raised temperature is not always a fever. [37]

Simplified control circuit of human thermoregulation. [8]The 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, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
