37.6 Is the underarm temperature normal?

Not normal.

According to the official inquiry of Health Road, the normal body temperature (underarm) is about 36℃ ~ 37℃. If the body temperature is within this range, it means that the body temperature is within the normal range. If the body temperature exceeds 37.3℃, it is fever and can be cooled by physical means. Therefore, the underarm temperature of 37.6 is abnormal.

Under the control of the thermoregulation center, the human body temperature keeps the dynamic balance of heat generation and heat dissipation, and keeps the body temperature within a constant range. There are many causes of body fever, including infectious fever and non-infectious fever. Infectious fever is the most common, mainly caused by various pathogens, such as bacteria, viruses, mycoplasma, chlamydia, rickettsia, fungi and so on.
