Introduction
Physical cooling methods are commonly used to reduce fever in infants and alleviate associated discomfort. Specific approaches include: - Using infant-specific cooling pillows or ice packs designed for babies—place them under the baby’s head or apply them to the forehead, especially when the fever is high. - Giving the baby a lukewarm bath—this is an effective cooling method, provided the room temperature is comfortable.

Because infants’ bodies are still developing and their immune systems are immature, they are prone to illness and fever. In most cases, medication is not recommended as the first-line treatment; instead, physical cooling methods are commonly used to alleviate discomfort associated with fever. Specific approaches include the following:

① Cold compress with an ice pack

Specialized infant-sized cold packs or cooling pillows designed for babies—often containing a safe, temperature-stabilizing gel—can be refrigerated before use. Once removed from the refrigerator, these retain a cool (but not freezing) temperature for an extended period. They may be placed under the baby’s head or applied gently to the forehead, particularly when fever is high. Note: Infants under six months of age should generally avoid using cold packs or cooling pillows, as rapid or excessive cooling may cause adverse effects.

② Wiping with lukewarm water

Gently wipe the baby’s body with a warm, damp towel—focusing especially on the head, limbs, axillae (armpits), groin (upper inner thighs), and other areas with abundant blood flow—to promote heat dissipation through evaporation. If ambient room temperature is comfortable, giving the baby a lukewarm bath is also an effective way to lower body temperature. In cases of high fever, alcohol sponging of the limbs and back may be considered to accelerate cooling—but only under medical guidance and with caution, as alcohol absorption through infant skin poses risks.

③ Lowering ambient room temperature

Fever reduction relies partly on heat exchange between the infant and the surrounding environment. A cooler environment facilitates more efficient heat loss. The optimal room temperature for fever management is 20–24°C, which supports gradual, safe reduction in body temperature. Especially during summer, simply loosening or removing excess clothing and placing the baby in a cool, shaded area often suffices to allow natural cooling. However, this method is inappropriate during the early febrile phase if the infant exhibits chills or shivering—a sign that core body temperature is still rising.
