How to Physically Reduce Fever in Babies

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, they maintain a cool (but not freezing) temperature for an extended period. These may be placed under the baby’s head or applied gently to the forehead, particularly when fever is high. However, cold packs or cooling pillows should generally be avoided in infants younger than 6 months, as rapid or excessive cooling may cause adverse effects.

② Warm-water sponging

A warm, damp towel can be used to gently wipe the baby’s body—especially the head, limbs, axillae (armpits), groin (upper inner thighs), and neck—to promote heat dissipation through evaporation. If ambient room temperature is comfortable, giving the baby a lukewarm bath is also an effective way to help reduce fever. In cases of high fever, alcohol sponging of the limbs and back may be considered to accelerate cooling—but only under medical guidance, as alcohol absorption through infant skin poses risks.

③ Lowering ambient room temperature

Fever reduction relies 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 of body temperature. During summer, simply loosening or removing the baby’s clothing and placing them in a shaded, well-ventilated area often suffices to lower body temperature gradually. However, this method is inappropriate during the early febrile phase if the infant exhibits chills or shivering—signs that body temperature is still rising.
