Introduction
Cold compresses can generally help reduce fever. As a form of physical cooling, cold compresses may be applied to areas such as the armpits, neck, and groin when body temperature is below 38°C. This promotes gradual reduction of overall body temperature through lymphatic circulation. However, for fevers exceeding 38.5°C, cold compresses alone usually do not achieve effective fever reduction. In such cases, medications such as ibuprofen or acetaminophen should be used according to medical advice.
Cold compresses can generally help reduce fever, but attention should be paid to the duration of application.
Cold compress is a form of physical cooling that lowers the temperature of blood in local blood vessels and helps remove excess body heat, thereby reducing fever. If body temperature is below 38°C, cold compresses can be applied to areas such as the armpits, neck, and groin. Through lymphatic circulation, this can gradually lower overall body temperature. However, when body temperature exceeds 38.5°C, cold compresses alone often do not provide effective fever reduction. In such cases, it's recommended to use medications as directed by a physician alongside cold compresses—such as ibuprofen or acetaminophen—to achieve better fever control.
When applying cold compresses, patients should avoid prolonged application, as excessive duration may damage local skin tissue. Additionally, if body temperature continues to rise, adverse reactions such as increased heart rate may occur. Therefore, it is advisable to seek timely medical evaluation and appropriate treatment at a hospital.
