How normal is the oral temperature?

The normal temperature of the human mouth is 36.3-37.2 degrees. When using an oral thermometer, you should put the thermometer under your tongue and shut it for about three minutes before taking it out. The result is more accurate. The temperature of the human mouth will be slightly higher than the armpit temperature by 0.2-0.4 degrees. After eating or strenuous exercise, the body temperature will rise.
