The normal body temperature for healthy adults is approximately 37°C. A fever is usually when your body temperature is 37.8°C or higher. However, normal body temperature can vary slightly from person to person and can change during the day. According to Holland & Barrett, the normal temperature for healthy adults is from 36.1 – 37.2 degrees centigrade. The Express reports that typically an adult’s normal body temperature will be around 37C, but everyone’s baseline will be slightly different.

It is important to note that extremely high or low body temperatures can be a cause for concern. With healthy adults, a moderate fever where your temperatures rise slightly should not be a significant cause of concern. However, adults with temperatures above 40C and below 35C should consult a medical professional, especially if there are other alarming symptoms such as headaches and shortness of breath.

In summary, the normal body temperature for healthy adults is approximately 37°C, but it can vary slightly from person to person and can change during the day. If you have a temperature of 37.8°C or higher, you may have a fever. If you have an extremely high or low body temperature, you should consult a medical professional.
