Is 38.4°C considered a high fever?

　　38.4°C usually refers to an axillary temperature of 38.4°C, and high fever generally means hyperpyrexia. Under normal circumstances, an axillary temperature of 38.4°C is not considered a high fever, but medical treatment should still be followed as directed. The detailed analysis is as follows:

　　Regarding body temperature classification, axillary temperature up to 37.3°C is considered normal; 37.4°C to 38°C is classified as low-grade fever, 38.1°C to 39°C as moderate fever, and 39.1°C to 41°C as high fever. Therefore, an axillary temperature of 38.4°C does not qualify as a high fever. Fever may be caused by infections, immune disorders, or other factors. When body temperature does not exceed 38.5°C, patients can use physical methods such as drinking more water or wiping the groin area with a warm towel to help reduce fever.

If the temperature continues to rise, medications such as ibuprofen sustained-release capsules or aspirin tablets may be taken under medical guidance. If symptoms persist without improvement, patients should seek timely medical attention and receive targeted treatment under a doctor's supervision to prevent continuous temperature elevation that could lead to high or even extremely high fever, endangering health.

　　During treatment, patients should maintain a positive mindset and ensure adequate sleep to support a quicker recovery.
