What physiological state is indicated by a core body temperature below 97°F?

A core body temperature below 97°F indicates a physiological state of hypothermia. Hypothermia occurs when the body loses heat faster than it can produce it, leading to a drop in core temperature. This condition can result from exposure to cold environments, wet conditions, or inadequate clothing, and it is critical to recognize as it can lead to serious health complications, including impaired brain function and, in severe cases, can be life-threatening.

In the context of evaluating body temperature, fever generally indicates an elevated temperature often associated with infection or illness, while normothermia refers to a normal body temperature range, typically around 98.6°F (37°C). Hyperthermia signifies an abnormally high body temperature and is often the result of environmental factors or intense physical exertion.
