Fever-reducing patches are indeed effective in lowering body temperature. The cooling principle of fever-reducing patches mainly utilizes the physical cooling process of liquid turning into gas, specifically the principle of water vaporization and heat absorption. When a fever-reducing patch is applied to the skin, the hydrophilic gel within absorbs and dissipates excess heat from the body, thus achieving a cooling effect.
Fever-reducing patches are particularly suitable for children with body temperatures below 38.5°C. For fevers within this temperature range, using fever-reducing patches can effectively relieve the discomfort caused by elevated body temperature, reduce the need for medication, and minimize potential side effects. Furthermore, since fever-reducing patches are topical medications, they do not cause the pain of injections, and parents can easily use them themselves by following the instructions.
However, it is important to note that fever-reducing patches do not cure the underlying cause of the fever; they only serve as an adjunct to lowering the temperature. When the body temperature exceeds 38.5°C, using fever-reducing patches alone may not achieve the desired cooling effect, and in this case, it is necessary to combine them with other antipyretic medications.
