Introduction
Cooling patches mainly work by absorbing heat through the evaporation of water contained in their gel, helping to remove localized body heat and achieve a physical cooling effect. When a patient has a fever with a temperature below 38.5°C, the cooling patch can be applied to areas rich in blood vessels, such as the armpits, neck, and forehead, to achieve a cooling effect. Therefore, cooling patches are generally effective for reducing fever.
Reducing fever usually refers to fever reduction, and cooling patches are generally effective for this purpose.
Cooling patches, also known as cooling or fever-reducing patches, primarily work by using gel to absorb moisture that evaporates, thereby helping draw heat away from localized areas of the body and achieving a physical cooling effect. When patients develop a fever with a temperature below 38.5°C, applying cooling patches to areas rich in blood vessels—such as the armpits, neck, and forehead—can effectively reduce body temperature. Therefore, cooling patches are generally useful for reducing fever. However, if a patient's temperature exceeds 38.5°C, the cooling effect of these patches may not be particularly significant. In such cases, it is recommended that patients take antipyretic medications under medical guidance to lower their body temperature. Commonly used medications include ibuprofen sustained-release capsules and acetaminophen tablets.
In addition to actively reducing body temperature, treating the underlying cause is also important after developing a fever. For example, if the fever is caused by a viral infection, antiviral medications should be taken under medical supervision. Commonly prescribed drugs include ribavirin granules and ganciclovir tablets.
