Introduction
Under normal circumstances, an adult's body temperature of 37.1°C measured with a mercury thermometer is not considered fever. Clinically, a temperature above 37.3°C taken under the armpit is defined as fever; thus, 37.1°C falls within the normal range. Individuals whose temperature measures 37.1°C using a mercury thermometer should monitor for any changes in body temperature. If the temperature continues to rise, it is recommended to seek medical attention at a hospital promptly.

Under normal circumstances, a body temperature of 37.1°C measured with a mercury thermometer in adults is not considered fever. Clinically, fever is defined as an axillary temperature exceeding 37.3°C; thus, 37.1°C falls within the normal range. The detailed explanation is as follows:

A mercury thermometer can be placed under the armpit to measure body temperature. The normal range is generally considered to be between 36°C and 37.3°C. A reading above 37.3°C indicates fever. Under regulation by the body's thermoregulatory center, heat production and heat dissipation are usually maintained in a dynamic balance. When the body is affected by pyrogenic substances or when there is dysfunction of the thermoregulatory center, heat production may increase without a corresponding increase in heat dissipation, potentially leading to fever.

Individuals whose body temperature measures 37.1°C using a mercury thermometer should monitor for any changes in temperature. If the temperature continues to rise, it is recommended to seek medical attention at a hospital promptly.
