Question

Why do babies’ cheeks turn red during sleep when the body releases heat outward?

Answer

This situation often occurs during the spring and autumn seasons. While sleeping, the body releases heat outward, causing a significant amount of moisture to evaporate. Improper diet can lead to food accumulation and indigestion, which generally manifests as the child’s cheeks becoming rosy. Additionally, because the skin on a baby’s face and head is very thin and is richly supplied with blood vessels, when a large amount of blood flows through them, the vessels dilate and become thicker, resulting in redness. Since blood has a certain temperature, the face may feel warm. This is a normal physiological phenomenon and does not require treatment.
