What is the standard range for a normal body temperature in adults?

The standard range for a normal body temperature in adults is recognized as 97.0°F to 99.0°F. This range encompasses the typical variations that can occur due to factors such as time of day, activity levels, and individual metabolism. Body temperature is often cited with 98.6°F as an average, but clinical guidelines indicate that normal temperatures can reasonably vary from the lower threshold of 97.0°F to the higher threshold of 99.0°F. This broadened range better reflects the diversity in physiological responses among different individuals.

Other ranges provided might not fully encompass the flexibility observed in what constitutes normal body temperature across different adults. Understanding the standard range assists healthcare professionals in evaluating patient health and diagnosing potential conditions that could alter body temperature beyond this typical range.
