What areas of the body should be wiped with alcohol for cooling?
Under normal circumstances, alcohol cooling is mainly applied to areas rich in large blood vessels and with good heat dissipation, such as the forehead, both sides of the neck, armpits (axillae), groin, and inner sides of limbs. The evaporation of alcohol helps carry away body heat and thus reduces body temperature. A detailed analysis is as follows:

1. Forehead: The skin on the forehead is thin and densely populated with blood vessels, making it a common site for alcohol cooling. When wiping, use gauze or a towel soaked in diluted alcohol and gently wipe from the center of the forehead outward to both sides, taking care to prevent alcohol from entering the eyes.
2. Both sides of the neck: Major blood vessels such as the carotid arteries run along both sides of the neck, where blood flow is rapid. Wiping this area enables quick heat dissipation through the blood vessels, effectively lowering body temperature. During wiping, avoid the front part of the neck (the throat area), and focus instead on the skin behind the ears and down along both sides of the neck, using gentle motions.
3. Armpits: The armpits are regions where large blood vessels are concentrated, and the presence of skin folds provides ample space for heat dissipation, making them key sites for alcohol cooling. To wipe, raise the arm to fully expose the armpit, then repeatedly wipe the armpit skin and surrounding areas with alcohol-soaked gauze, applying moderate pressure.
4. Groin: The femoral arteries and other major vessels are located in the groin, which is also close to the body's core, resulting in significant cooling effects. During application, remove clothing to expose the groin area and gently wipe the groin and upper inner thighs with alcohol-soaked gauze, avoiding contact with mucosal areas of private parts.
5. Inner sides of limbs: The inner sides of arms and legs contain numerous small blood vessels and have relatively thin skin, making them suitable for alcohol wiping. Wipe slowly from the proximal to the distal end of the limb—for example, from elbow to wrist—to promote blood circulation and alcohol evaporation, thereby assisting in overall body cooling. Avoid wiping the outer sides of limbs and joint areas.
When using alcohol for cooling, ensure the alcohol concentration is not too high. Monitor the individual’s physical response during the process; discontinue immediately if shivering, skin redness, or other adverse reactions occur. Additionally, alcohol cooling is not recommended for infants, young children, or individuals with broken skin. In such cases, milder methods such as tepid water sponging are preferred.
