Which term refers to having a body temperature significantly above normal?

Hyperthermia is the term that refers to a body temperature that is significantly above normal levels. This condition occurs when the body's temperature regulation fails, and it can result from various factors such as excessive heat exposure, intense physical exertion, or certain medical conditions. The normal range for body temperature is typically around 98.6°F (37°C), and hyperthermia is typically recognized when temperatures rise above this threshold, possibly reaching dangerous levels that can lead to heat-related illnesses.

Understanding the nuances of hyperthermia is crucial, especially in contexts like sports medicine, outdoor activities, and occupational health, as it underscores the importance of maintaining a stable body temperature for overall health and performance. The other terms, while relevant in other contexts, do not specifically describe elevated body temperature.
