What is the normal body temperature range for a resting younger adult?

The normal body temperature range for a resting younger adult is commonly recognized to be between 97.0°F to 99.0°F. This range reflects a state of homeostasis where the body's thermoregulation is functioning properly. Individual variations can occur due to several factors, including the time of day, activity level, and method of measurement, but the generally accepted range for normal body temperature is rooted in a large body of clinical research.

Maintaining body temperature within this range is critical for ensuring optimal physiological function and metabolic processes. When temperatures fall outside of this range, it may indicate various health issues that require medical attention.
