What is the normal human body temperature in degrees Celsius?

A person’s normal body temperature typically ranges from 36.2°C to 37.2°C. Since metabolic rates vary among individuals, slight variations in body temperature are common. Generally, a temperature above 36.5°C is considered low-grade fever, while a temperature exceeding 39°C is classified as high fever and requires therapeutic cooling measures; otherwise, it may adversely affect health.
