Can cold compresses on the groin reduce fever?

　　Reducing fever, also known as antipyresis. Under normal circumstances, applying cold compresses to the groin area can help reduce fever. If necessary, it is recommended to seek timely medical attention. Detailed explanation is as follows:

　　The groin area contains a rich network of blood vessels, including important arteries such as the common femoral artery, through which blood flows to the lower limbs. When the body experiences a fever, these vessels carry blood with a higher temperature. Applying a cold compress can effectively lower the temperature of the blood within these vessels, thereby helping to reduce the overall body temperature. This physical cooling method acts directly on the circulatory system and is highly efficient in dissipating heat.

　　In addition, applying cold compresses to the groin area can stimulate local nerves and muscle tissues, prompting a series of physiological responses. These responses may include increased sweat gland secretion and accelerated heat dissipation, further promoting a decrease in body temperature. Especially during the early stages of fever, when body temperature rises rapidly, applying cold compresses to key areas such as the groin can quickly slow the rate of temperature increase, buying time for subsequent treatment.

　　Although applying cold compresses to the groin can help reduce fever, prolonged application may cause damage to the local skin tissue and even result in frostbite.
