So what is ‘Normal Temperature’ in Humans?

The normal temperature in humans ranges between 36.4 to 37.3 C°. But note, that this definition may be slightly different depending on textbook. For instance, some textbooks suggest that normal temperature ranges between 36.6 to 37.0 C°. However as long as it doesn’t exceed 38.0 C° and doesn’t fall below 36.0 C° you have nothing to be worried about.
