What is the normal body temperature for humans?

The normal body temperature for humans is considered to be around 37 degrees Celsius. This value is typically cited as the average normal body temperature, although it can vary slightly from person to person and can change depending on the time of day, level of physical activity, and various other factors. A reading at this temperature indicates a balanced internal environment, essential for optimal physiological functions.

Temperatures significantly lower than this may indicate hypothermia or illness, while higher temperatures can suggest fever or infection. Knowing that 37 degrees Celsius represents a healthy baseline is important for understanding how body temperature can fluctuate and what those changes might mean in terms of health and fitness.
