While the average was 98.6, he did notice that body temperature varies from person to person and also vary during different parts of the day.

Dr. Sharaang Sachdev, Consultant, and Coordinator – Emergency, Dharamshila Narayana Hospital say, “People think that fever is bad but it is body’s normal response.

  • It is lowest in the morning and little higher during the late afternoon.
  • Hence, people in the working population shouldn’t worry too much about 99 body temperature unless they have a severe infection.”

How you measure body temperature also plays a vital role. It depends on whether you are using oral thermometers, rectal or ear ones.

  • In children, a body temperature of 99.7 degrees F using oral or armpit thermometer is a fever.
  • For adults too, it will be 99.7 degrees or F.
  • Rectal temperature has to map a temperature of 100.4 degrees F or higher.

“Age tends to drive down temperature, so an older person with a temperature of 99 may be sick, while a younger one with the same temperature can be perfectly healthy”, said Jack A. Yanovski, chief of the Section on Growth and Obesity at the Eunice Kennedy Shriver National Institute of Child Health and Human Development in Bethesda
