There are several common methods for physically reducing fever in infants. The most commonly used method with the least side effects is using fever-reducing patches, typically applied to the baby's forehead, neck, and other areas, which are quite effective. Secondly, you can give the baby a wipe bath with warm water, focusing on areas with abundant capillaries and large blood vessels such as the neck, armpits, groin, and behind the knees. The third method involves giving the baby a warm bath, which helps dilate the capillaries on the baby's skin surface to achieve the effect of heat dissipation. However, it is important to keep warm during the bath to prevent catching a cold, and the bathing time should generally not exceed ten minutes. Additionally, appropriately hydrating the baby to prevent dehydration can enhance the cooling effect of the above methods.
