Which of the following describes the normal range for body temperature?

The normal range for body temperature is approximately 98.6°F, which is considered the average temperature for a healthy adult. This value is derived from various studies and is often used as a benchmark for assessing a person's health status. However, it is important to note that normal body temperature can vary slightly from person to person and can be influenced by factors such as time of day, physical activity, and individual metabolism.

In clinical settings, a temperature around this average indicates that the body's systems are functioning well, allowing for the optimal performance of physiological processes. Values significantly above or below this number can suggest an underlying condition. For instance, a temperature above 100°F can indicate fever or infection, while temperatures lower than 95°F may suggest hypothermia. The mention of being below freezing point does not relate to normal human body temperature, as it is well outside the viable range for human life and indicates severe hypothermia or other dangerous conditions.
