What is the normal range for adult body temperature?

The normal range for adult body temperature is widely accepted to be between 97°F and 100.4°F. This range reflects what is considered a healthy body temperature for most adults, given that individual variations can occur due to factors such as the time of day, activity level, and individual physiology.

The average normal body temperature is often cited as 98.6°F, but it's important to recognize that the range can extend slightly above and below this average due to normal physiological variations. In this context, the selected range encompasses temperatures that are typically seen in healthy adults, providing a reliable benchmark for assessing health status.

Understanding this range is crucial for identifying fevers or other health concerns, as temperatures outside this range could indicate underlying medical issues. For instance, a temperature exceeding 100.4°F might warrant further investigation for potential infections or other health problems.
