Whether 37.3 degrees is a normal temperature for an adult depends on the part of the body where the temperature is measured. Temperatures vary from one part of the body to another, and the range of normal values also varies. Normal adult body temperature is: measured by the oral cavity temperature of 36.3 ~ 37.2 degrees, measured by the rectum temperature of 36.5 ~ 37.7 degrees, measured by the armpit temperature of 36.0 ~ 37.0 degrees, so from the oral cavity, armpit temperature measurement, adults 37.3 degrees belongs to the fever, and from the rectal measurement of the temperature, adults 37.3 degrees belongs to the normal body temperature. Because the body temperature of different parts of the body is not quite the same, so the normal value is different, if adults 37.3 degrees also appeared dizziness, nausea and other symptoms, we should go to the hospital in time to identify the cause, and carry out appropriate treatment.
