Patient's question:
My baby is still under one year old, but I've noticed something quite unusual about him—he sweats a lot from his head, yet doesn't sweat on his body. It's especially noticeable when he's nursing, and even his small pillow gets damp with sweat at night. Other than that, he's usually very good-natured.What kind of help would you like: Is it a sign of poor health that his head sweats so much?
Doctor's answer:
My baby is still under one year old. His head always sweats very easily, while his body never sweats. Especially when he is nursing, he sweats a lot. Even his small pillow gets damp with sweat when he naps at night. I suspect it might be due to thirst. Sweating is a physiological phenomenon, which is the process by which the body releases sweat to dissipate heat and maintain normal body temperature. Excessive sweating is called hyperhidrosis, which is divided into physiological and pathological types. Most infants and toddlers have physiological hyperhidrosis. This is because their skin contains a high amount of moisture and has rich capillaries, so the amount of water evaporated through the skin is relatively high. Moreover, infants and toddlers are active and restless, so they naturally sweat more than adults.
