Adults with a fever of 37.9 degrees are considered to have a low-grade fever.
Normal adult body temperature is about 36 degrees to 37 degrees, can be slightly different due to different measurement methods, and often subject to internal and external factors and fluctuations. Currently, an axillary temperature of 37.3 degrees to 38 degrees is considered a low fever, and 39.1 degrees to 40 degrees is considered a high fever, so 37.9 degrees is considered a low fever.
A temperature of 37.9 degrees may be caused by microbial infections, inflammatory exudates, antigen-antibody complexes, and other causes of fever. Physical hypothermia can be used for temperature control.
If the body temperature does not fall or even rises, you need to go to the hospital in time, under the guidance of the doctor, so as not to delay the condition.
