Axillary body temperature 37.3℃ is an abnormal temperature because it is slightly higher than the normal axillary body temperature, but it has not reached the state of fever, because the normal range of axillary body temperature is between 36-37℃, and now the axillary body temperature reaches 37.3℃, which is slightly higher than the normal value, but it has not reached the state of fever. The state of low fever ranges only between 37.4-38℃, just a little lower than fever, but at this time some patients will have an uncomfortable state, such as weakness, dizziness and other symptoms, and need to drink more water, rest more, and use physical cooling methods to bring the body temperature down to normal, without the need to use antipyretic drugs for treatment.
