Normal axillary temperature range

In daily life, we commonly measure body temperature via the axillary (underarm) route. Some patients wish to know what constitutes a normal axillary temperature. So, what is the normal range for axillary temperature?

Normal Axillary Temperature Range

The normal axillary temperature ranges from 36°C to 37°C—approximately 0.5°C lower than rectal temperature. When measuring axillary temperature, ensure the mercury bulb of the thermometer is in direct, firm contact with the skin. Place the thermometer snugly in the axilla and keep the skin fully surrounding it. Maintain this position for at least five minutes. Additionally, placing ice packs under the arm, applying heat therapy, or performing an alcohol rub can all affect measurement accuracy. If accurate temperature assessment is required, avoid applying either heat or cold to one axilla beforehand, as this may compromise the reliability of the reading.

Causes of elevated body temperature fall into two categories: physiological and pathological. Physiological elevation refers to a temporary, non-disease-related rise in temperature—most commonly observed during physical activity. Exercise increases heat production, leading to a noticeable rise in body temperature. Furthermore, in women, progesterone secretion before menstruation may cause a slight, transient increase in basal body temperature.

If an elevated temperature is detected during routine measurement, promptly seek medical evaluation and prioritize adequate rest. We hope this article has been helpful. Wishing you good health and a joyful life!
