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. Direct pharmacological treatment is generally not recommended; 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
Specially designed infant head-cooling pillows or ice packs—containing a unique gel formulation—may be used. These should be chilled in the refrigerator prior to use and will maintain a cool temperature for an extended period. During use, place the pillow beneath the infant’s head or apply the ice pack to the forehead. This method is particularly suitable for cases of high-grade fever. However, infants under six months of age should avoid using cooling pillows or ice packs, as rapid or excessive cooling may cause adverse effects.
② Wiping with lukewarm water
Gently wipe the infant’s body with a warm, damp towel—especially over the head, limbs, axillae (armpits), groin (upper inner thighs), and other areas—to promote heat dissipation via evaporation from the skin surface. If ambient room temperature is comfortable, giving the infant a lukewarm bath is also an effective means of reducing fever. In cases of high fever, alcohol sponging of the limbs and back may be employed to facilitate more rapid cooling.
③ Lowering ambient room temperature
Fever reduction in infants relies on heat exchange between the body and its surroundings. A cooler environment facilitates more efficient heat loss; the optimal room temperature for gradual, safe fever reduction lies between 20°C and 24°C. Especially during summer, simply loosening or removing the infant’s clothing and placing them in a cool, shaded area often suffices to gradually lower their body temperature. However, this method is inappropriate during the early febrile phase if the infant exhibits chills or shivering—signs indicating that core body temperature is still rising.
