Can you use an electric fan when you have a fever?

Generally speaking, it is acceptable to use an electric fan when experiencing fever, but one should avoid direct blowing. The detailed explanation is as follows:

When the body has a fever, heat production increases and heat dissipation decreases. At this time, skin blood vessels constrict and blood flow reduces, which may cause skin temperature to drop, making the patient feel cold or experience chills. If an electric fan blows directly on the body at this stage, it may worsen the sensation of coldness and chills. It is generally recommended that patients wipe their bodies with lukewarm water or take a warm bath. During fever, patients are in a state of illness, often physically weak with reduced resistance. Direct exposure to an electric fan can easily lead to chilling, allowing pathogenic microorganisms such as bacteria and viruses to invade and potentially worsen the condition. It should be noted that although direct blowing should be avoided, using a fan to circulate air in the surrounding environment is acceptable and can help lower ambient temperature, thereby aiding the body's heat dissipation.

Patients experiencing fever symptoms are advised to promptly visit the fever clinic at a hospital to determine the underlying cause and receive targeted treatment, which is essential for effectively controlling body temperature.
