Is a body temperature of 37°C normal?

A body temperature of 37°C is considered normal. Body temperature—the internal temperature of the human body—is generated as a byproduct of metabolic processes converting substances into thermal energy. Maintaining a stable core temperature is essential for ensuring normal metabolism and physiological function. Normal body temperature is not a single fixed value but rather a range.

Normal reference ranges: - Sublingual (oral) temperature: 36.3–37.2°C - Rectal temperature: 36.5–37.7°C (0.2–0.5°C higher than oral temperature) - Axillary (underarm) temperature: 36.0–37.0°C These standard values are derived from population-based data and do not represent absolute thresholds for every individual. Body temperature may fluctuate depending on physiological conditions and environmental factors, but deviations should remain within the established normal range.

However, a temperature exceeding 38.1°C is classified as fever (hyperthermia), and medical consultation is generally recommended to guide appropriate pharmacological treatment.
