Why Does My Baby Sweat While Sleeping?

Sweating during sleep is quite common for babies. Sometimes, it is a normal phenomenon, but sometimes it can be a sign of a physical illness. Parents need to learn to distinguish whether the sweating is physiological or pathological. During summer, when the weather is hot, we usually turn on the air conditioning indoors, especially when sleeping at night. Some babies still sweat even when sleeping with the air conditioning on. What could be the reason for this? Sweating while sleeping in an air-conditioned room is usually a pathological condition that parents should take seriously. It is often due to calcium deficiency. It is recommended to take your child to the hospital for a bone density test as soon as possible and supplement calcium under the guidance of a doctor.

1. Physiological Reasons: During infancy, due to their active metabolism and lively nature, some babies may continue to be restless even after going to bed at night, resulting in sweating on their heads while asleep. Parents often tend to determine the optimal environmental temperature for their children based on their subjective feelings and may over-cover them with blankets. Since the nervous system of a child's brain is not fully developed and they are in a period of growth and development, their metabolism is very active. Coupled with the stimulating effect of excessive heat, they can only regulate their normal body temperature by sweating to evaporate the heat inside their bodies.

2. Nursing Reasons: Parents' tendency to determine the optimal environmental temperature for their babies based on their subjective feelings and over-covering them with blankets can also contribute to their sweating while sleeping. Sometimes, even when the weather is not cold, parents may dress their babies in excessive clothing, which can also lead to sweating during sleep. For some active children, the large amount of exercise during the day generates excess heat that their bodies cannot dissipate through sweating. This heat accumulates in their bodies, and their body temperature can reach around 38°C at night. After falling asleep, the production of heat decreases, the sensitivity of the sympathetic nervous system weakens, and the body dissipates excess heat through sweating to maintain a normal body temperature.

3. Dietary Reasons: Many parents are often concerned about their babies' nutrition and try various ways to supplement their diets. Some parents give their babies milk or malt extract before bedtime, which can lead to increased heat production in the body after falling asleep. This heat is dissipated through skin sweating, causing the baby to sweat during sleep. Drinking milk, malt extract, or eating chocolate before bedtime can also cause sweating in children. When parents give their children milk or malt extract before bedtime, the large amount of heat produced by their bodies after falling asleep is mainly dissipated through skin sweating.
