Fever of 38℃ usually cannot be reduced by itself, but there are individual patients with relatively strong resistance who can reduce fever by themselves. The use of antipyretic drugs is usually not considered for fever 38℃. You can drink more water or promote the reduction of fever by physical cooling to relieve the discomfort brought by fever to the organism. There are many causes of fever, and a fever of 38℃ does not necessarily reduce the fever by itself. If a patient has a fever caused by a common viral cold, the symptoms are mild, the patient’s resistance is relatively good, and the fever often manifests itself as a transient one, which may appear to reduce the fever on its own. Some patients may have fever caused by wearing too thick clothes. By wearing less clothes, covering less blankets and drinking more warm water, the fever may also appear to go down on its own. Some patients with a fever of 38℃ can subside for a short time, but the temperature will fluctuate repeatedly. This is a fever that may be caused by viral, bacterial or mycoplasma infections, etc. The fever cannot subside on its own if the pathogens in the body are not controlled, and the temperature will even rise further unless the pathogens are completely removed and the fever will gradually stop. If you have a fever of 38 degrees Celsius, you need to improve the relevant tests to clarify the diagnosis, and then target anti-infection treatment. A fever of 38℃ generally cannot be reduced by itself. You can physically cool the fever by drinking more hot water, applying ice packs and taking warm water baths, and at the same time closely monitor the change in body temperature. If the body temperature continues to rise, you should seek medical treatment promptly.
