Hyperthermia is defined as a core temperature above which degree Fahrenheit?

Hyperthermia is defined as a core body temperature that exceeds 100.4°F. This temperature threshold is significant as it indicates the body's inability to dissipate heat under conditions of excessive heat exposure or during intense physical activity, leading to a potential medical crisis. The body's thermoregulatory mechanisms become overwhelmed, resulting in elevated body temperature, which can pose serious health risks. Understanding this definition is crucial for identifying and managing conditions related to heat stress, such as heat exhaustion or heat stroke.

The other temperatures listed do not accurately define hyperthermia according to medical standards, as they fall below the critical threshold of 100.4°F, which is considered the onset of abnormal heat retention. Recognizing this distinction is essential for effective diagnosis and intervention in situations involving heat-related illnesses.
