Introduction
The human body maintaining a normal body temperature ensures proper metabolism and vital activities. Under normal circumstances, the axillary (underarm) temperature ranges between 36–37°C; therefore, an axillary temperature of 37°C in adults is considered normal, and individuals do not need to be overly concerned. However, if an adult's axillary temperature exceeds 37.3°C, it is classified as low-grade fever and warrants attention. It is advisable to actively identify the underlying cause and proceed with targeted treatment accordingly.
An adult's axillary temperature of 37℃ is generally considered normal.
The human body maintains a stable body temperature to ensure normal metabolism and vital activities. Body temperature is regulated primarily by the thermoregulatory center located in the brain and hypothalamus, which balances heat production and heat dissipation through neurohumoral regulation. Under normal circumstances, the axillary temperature ranges between 36°C and 37°C; therefore, an axillary temperature of 37°C in adults falls within the normal range, and individuals do not need to be overly concerned. Although slight fluctuations in body temperature may occur due to external factors—such as after physical exercise, in excessively warm indoor environments, or following meals—these typically do not cause significant changes in body temperature.
If an adult's axillary temperature exceeds 37.3°C, it is considered a low-grade fever and should be monitored closely. It is advisable to actively identify the underlying cause and treat accordingly. For instance, if the fever is caused by a viral infection, antiviral medications such as Acyclovir tablets or Ganciclovir tablets may be recommended under a physician's guidance.
