What does the temperature of a human body indicate from lowest and highest temps compatible with life?

The normal human body temperature typically ranges from about 97°F (36.1°C) to 99°F (37.2°C). A body temperature below 95°F (35°C) indicates hypothermia, which can be life-threatening, while temperatures above 104°F (40°C) can lead to hyperthermia, potentially causing organ failure. These temperature extremes reflect the body's ability to regulate its internal environment, and deviations can signal serious health issues. Maintaining a stable temperature is crucial for metabolic processes and overall health.
