The normal human body temperature is

The normal human body temperature is (a) 98.4 °F. This temperature represents the average internal body temperature for most individuals when measured orally. It serves as a crucial indicator of overall health and homeostasis. Deviations from this normal range can signify underlying health conditions, such as fever or hypothermia. Maintaining a stable body temperature is essential for optimal physiological function, as various enzymatic reactions, metabolic processes, and cellular functions are temperature-dependent. The body regulates its temperature through mechanisms such as sweating, shivering, and adjustments in blood flow to the skin. While factors like age, activity level, and time of day can influence body temperature slightly, the average healthy adult typically maintains a body temperature close to 98.4 °F. Therefore, this temperature serves as a standard reference point for assessing an individual’s thermal status and overall well-being.
