Normal Body Temperature and the Periodic Fever Syndromes. Any temperature in the range of 97.0 F to 100.0 F is not generally a cause for concern for healthy individuals. But there is more to autoinflammatory diseases than the body temperature. For over 100 years, 98.6 degrees F (or 37 degrees C) has been accepted as the standard for a normal body temp. This became the standard after a German physician, Dr. Carl Wunderlich, recorded auxiliary (armpit) temperatures from about 25,000 people in the 1800s.
