Patient's question:
NoDoctor's answer:
It is normal for children to sweat, as their sweat glands are more developed. Sweat secretion is controlled by the autonomic nervous system (vagus nerve). After falling asleep, the excitement of the vagus nerve leads to increased sweating, usually concentrated on the head and face, but it typically subsides within one to two hours. If sweating persists after sleep and is significant in amount, it could be a sign of a functional disorder of the autonomic nervous system, with some cases possibly caused by calcium deficiency. Additionally, children who are active and have high levels of physical activity tend to sweat more easily.
