Fever-reducing patches primarily work by using the physical change of water vaporization to absorb heat, thus achieving a cooling effect-a method of physical cooling.
The main ingredients of fever-reducing patches include menthol oil and gel, and they are characterized by safe fever reduction and brain protection.
After using a fever-reducing patch, the affected area will feel cool. As the skin absorbs the heat, the area releases heat, lowering body temperature and slowing its rise. This primarily lowers the temperature in the brain, slowing down brain metabolism and protecting brain cells. Fever-reducing patches are suitable for fever caused by colds or infections due to their physical heat dissipation effect.
However, fever-reducing patches currently only provide supplementary fever reduction. For persistent high fever that does not improve, it is best to use medication to reduce the fever promptly, such as ibuprofen or acetaminophen, to prevent adverse effects on the brain and nervous system. Adequate hydration is also important when fever is present.
