Is 37.7°C considered a fever?

A commonly measured axillary temperature of 37.7°C is considered a fever—specifically, a low-grade fever, as the low-grade fever range is 37.4–38.0°C. Normal human body temperature typically falls between 36.0°C and 37.0°C.

Low-grade fever may be caused by the common cold. It is recommended to monitor for associated symptoms such as sore throat, fatigue, cough, or pharyngeal pain. Close observation during this period is also advised to determine whether the low-grade fever stems from other underlying conditions.

Since a temperature of 37.7°C is not markedly elevated, physical cooling methods are recommended for fever reduction. Consuming light, easily digestible foods and maintaining a regular sleep-wake schedule over the coming days can promote improvement. Adequate sleep also supports recovery from illness.

During illness, increasing fluid intake and urination frequency is an effective way to dissipate excess body heat. If low-grade fever persists, it may reflect relatively low immune function and slower recovery. In such cases, appropriate warmth preservation is essential, and prompt medical consultation is advised if symptoms worsen.
