Is 37°C in the armpit normal?

Axillary temperature of 37°C is generally considered normal, as body temperature may vary due to environmental factors.

Under normal circumstances, the human axillary temperature ranges between 36°C and 37.2°C. A reading of 37°C falls within the normal range for axillary temperature and is typically not regarded as fever. Body temperature can fluctuate under the influence of environmental conditions—for example, high ambient temperatures or wearing excessive clothing may impair heat dissipation and lead to a temporary rise in body temperature. Daily fluctuations of approximately 1°C are common. Additionally, body temperature varies among individuals depending on physical constitution. For instance, newborns and infants tend to have slightly higher body temperatures than adults due to their faster metabolic rates. As long as the axillary temperature does not exceed 37.2°C, it is considered within the normal range.

If the axillary temperature is 37°C and no other adverse symptoms are present, no specific treatment is required. However, it's important to closely monitor any changes in body temperature. If the temperature rises above 37.3°C, physical cooling methods such as wiping the body with lukewarm water can be used. It is also advisable to drink more water to enhance metabolism.
