Is 37.2°C considered a low-grade fever?

Low-grade fever usually refers to mild fever. Under normal circumstances, the normal temperature measured rectally ranges from 36.9°C to 37.9°C, orally from 36.3°C to 37.2°C, and axillary (underarm) measurement ranges from 36.1°C to 37.0°C. If rectal or oral measurement is used, a temperature of 37.2°C is generally not considered a low-grade fever. However, if axillary measurement is used, it would be classified as a low-grade fever. If a low-grade fever occurs, it is recommended to seek medical attention promptly. Detailed analysis is as follows:

1. Not a low-grade fever

Body temperature measurement is one of the important indicators for assessing health status. The normal temperature range varies depending on the measurement site. Typically, the normal rectal temperature ranges from 36.9°C to 37.9°C, oral temperature from 36.3°C to 37.2°C, and axillary temperature from 36.1°C to 37.0°C. If rectal or oral measurement is used, a body temperature of 37.2°C does not fall within the range of low-grade fever.

2. Is a low-grade fever

If axillary measurement is used, a body temperature of 37.2°C falls within the range of low-grade fever. Axillary temperature is usually slightly lower than rectal or oral temperature; therefore, when axillary temperature reaches or exceeds 37.0°C, it should be taken seriously. A low-grade fever may be a sign of an underlying illness or infection. It is advisable to seek medical evaluation promptly, undergo appropriate tests to determine the cause, and receive corresponding treatment.

In daily life, patients should ensure proper warmth to avoid catching a chill, get adequate rest, and avoid excessive fatigue.
