Is an armpit temperature of 37.5°C measured by a mercury thermometer considered a fever?

Fever usually refers to an elevated body temperature. The normal axillary temperature ranges between 36.1°C and 37°C. If the measurement is taken after physical exercise or eating, and there are no accompanying bodily discomforts, an axillary temperature of 37.5°C measured with a mercury thermometer does not necessarily indicate fever; however, if there are abnormal symptoms present, it may be considered fever. If an axillary temperature of 37.5°C persists over a long period and standard treatments show little effect, timely medical consultation is recommended. Detailed analysis is as follows:

1. Not considered fever

After intense physical activity or meals, axillary temperature may rise. At such times, using a mercury thermometer to measure underarm temperature might yield a reading of 37.5°C. If there are no uncomfortable symptoms, this is generally a normal physiological response and not considered fever. It is recommended to rest appropriately, drink warm water, and then re-measure the temperature.

2. Considered fever

If the individual experiences noticeable symptoms such as muscle aches, fatigue, drowsiness, and these persist for a prolonged period, then an axillary temperature of 37.5°C measured with a mercury thermometer should be regarded as fever. General treatments such as tepid sponging the forehead, neck, and armpits can be used to promote heat dissipation from the body surface and reduce body temperature.

In daily life, engaging in appropriate physical activities such as running or hiking can help enhance resistance and reduce the likelihood of illness.
