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).
Body temperature, which is systematically measured and reported as a vital sign, contributes to maintenance of normal physiology and affects the processes that lead to recovery after illness. Complete and proper functioning of the body is dependent on maintaining a core temperature between 36.5–38.5 °C (97.7–101.3 °F).
Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.

Human rhinoviruses preferentially grow at 33 °C (91.4 °F), notably colder than the average human body temperature of 37 °C (98.6 °F), hence the virus's tendency to infect the upper respiratory tract, where respiratory airflow is in continual contact with the (colder) extrasomatic environment.

[168] [169] Like many other conditions, body weight and body type are influenced by both genetic susceptibility and environment and varies greatly among individuals. [170] [171] Humans have a far faster and more accurate throw than other animals. [172]
Anders Celsius's original thermometer used a reversed scale, with 100 as the freezing point and 0 as the boiling point of water.. In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale that was the reverse of the scale now known as "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water.

Dizziness, blurred vision, dry mouth, hypertension, nausea, increased or decreased body temperature, or feeling flushed are the common (>10%) non-psychiatric side effects. All these adverse effects are most pronounced by the end of the injection, dramatically reduced 40 minutes afterward, and completely disappear within 4 hours after the injection.
Infection may initiate a chain of vasoconstrictive responses within the body, including pulmonary vasoconstriction – a possible mechanism in which oxygenation decreases during pneumonia. [151] Furthermore, damage of arterioles and capillaries was found in brain tissue samples of people who died from COVID‑19.
