Normal Body Temperature: What's Considered Healthy?

Normal human body temperature

The average normal human body temperature is generally considered to be 37.0 °C (98.6 °F), although it can vary slightly from person to person. Body temperature is regulated by the body's hypothalamus, which acts like a thermostat and maintains a constant internal environment. Normal body temperature can fluctuate throughout the day, with lower temperatures in the morning and higher temperatures in the evening. Additionally, body temperature can vary depending on factors such as age, physical activity, and illness.
