The condition where the internal body temperature exceeds the normal range is known as hyperthermia. This occurs when the body is unable to dissipate heat effectively, leading to an increase in body temperature above the typical range of approximately 36.1°C to 37.2°C (97°F to 99°F). Hyperthermia can result from a variety of factors, including environmental heat exposure, vigorous exercise, illness, or certain medical conditions.

Understanding this condition is essential, as it can lead to serious health issues such as heat exhaustion or heat stroke if not addressed promptly. Recognizing the signs of hyperthermia, such as excessive sweating, dizziness, and confusion, is critical for timely intervention and cooling measures.

In contrast, hypothermia refers to abnormally low body temperature, normothermia describes the normal temperature range, and thermostasis refers to the body's mechanisms for maintaining stable internal temperature.
