Introduction
In general, fever refers to an elevated body temperature. In summer, it is acceptable to use a fan while sleeping during a fever, but care should be taken to avoid direct blowing of the fan on the patient to prevent worsening of fever symptoms. During fever, body temperature rises, blood vessels dilate, and blood circulation accelerates, which may cause noticeable sensations of heat and discomfort. At night in summer, the surrounding ambient temperature is often high, making patients prone to sweating and even dehydration.
Generally speaking, fever refers to an elevated body temperature. During summer, it is acceptable for a person with fever to sleep with a fan running, but care should be taken to avoid direct airflow from the fan onto the patient, as this may worsen the fever symptoms. The specific reasons are as follows:
During fever, body temperature rises and blood vessels throughout the body dilate, accelerating blood circulation. This often causes noticeable sensations of heat and discomfort. At night in summer, the surrounding environment is typically warm, which may exacerbate fever, cause excessive sweating, or even lead to dehydration.
Using an electric fan appropriately can help maintain indoor air circulation and a comfortable ambient temperature, effectively removing heat released through the patient's skin and promoting better cooling. However, direct blowing on the patient should be avoided because, during fever, pores are open and direct airflow may impair proper heat dissipation, potentially worsening the fever symptoms.
While using a fan to maintain a suitable environment during fever, it is also important to monitor body temperature regularly and follow medical advice regarding antipyretic treatment, which supports recovery.
