Introduction
Mercury thermometers are a commonly used method for measuring body temperature, and they are simple, quick, and highly accurate. Generally, there is no need to add 0.5°C to the reading; the displayed value typically reflects the current body temperature directly. The normal axillary (underarm) temperature ranges from 36°C to 37.2°C. A temperature above 37.2°C may indicate fever, and repeated measurements should be taken to confirm.
Under normal circumstances, there is no need to add 0.5°C when measuring axillary temperature with a mercury thermometer; simply take the reading as it appears. Specific details are as follows:
Mercury thermometers are commonly used for body temperature measurement due to their simplicity, speed, and high accuracy. When measuring axillary temperature, it is generally not necessary to add 0.5°C—the reading obtained is the current body temperature. Normal axillary temperature ranges from 36°C to 37.2°C. A temperature exceeding 37.2°C may indicate fever, which should be confirmed through repeated measurements. Once fever is detected, appropriate cooling measures should be taken based on the body temperature. If body temperature is below 38.5°C, cooling methods such as lukewarm baths or alcohol wipes may be used. If temperature exceeds 38.5°C, medications such as ibuprofen tablets, acetaminophen (paracetamol) tablets, or indomethacin tablets may be used under medical guidance to help relieve symptoms.
If a patient experiences discomfort or other concerning symptoms, prompt medical evaluation at a hospital is recommended to prevent serious complications. Maintaining healthy lifestyle habits in daily life contributes to overall health.
