Normal axillary body temperature range for adults in summer
The normal axillary body temperature for adults in summer ranges from 35.5–37.3°C.
Body temperature is regulated by the hypothalamus, and generally stays between 36–37°C. During summer, body temperature may fluctuate slightly due to internal and external factors, usually within 1°C. A mildly elevated temperature caused by intense physical activity or high mental stress is considered physiological.
If axillary temperature exceeds 37.3°C, it indicates fever; if it falls below 35.5°C, it suggests hypothermia. In such cases, first dry any sweat under the armpits, apply gentle pressure with your hand for 5 minutes, then retake the measurement to ensure accuracy. When body temperature rises above 37.3°C, initial management should involve physical cooling—wiping the limbs, chest, back, and areas rich in blood vessels such as the armpits, groin, and popliteal fossae with lukewarm water can help dissipate heat; extending the wiping time appropriately enhances effectiveness. If fever persists, applying a cooling patch to the forehead may help. If body temperature remains elevated, seek medical attention promptly.
It is advisable to avoid exposure to cold, excessive fatigue, and consumption of spicy or irritating foods in daily life to help prevent illness.
