If the temperature is measured anally, the normal temperature is between 36.5 and 37.7 degrees, so 37.3 degrees is considered a very normal temperature range. It is also a very normal phenomenon if the body temperature is always at 37.3 degrees. If the temperature is measured in the mouth or in the armpit, 37.3 degrees has a little bit of fever. If the temperature is measured in the armpit, the normal temperature is between 36.0 and 37.0 degrees. If the temperature is measured in the mouth, the normal temperature is between 36.3-37.2 degrees, so 37.3 degrees is considered to have a fever that is not quite normal. First of all, we should find the cause of low fever for targeted treatment, the temperature is not particularly high, it is not necessary to carry out antipyretic treatment, when a cold occurs, you can use cold medicine, such as cold and fever granules or cold and flu granules for treatment, the effect is relatively good, so it is very important to find the cause of fever.
