Why does my 4-month-old baby always sweat?

My 4-month-old baby always sweats on his head. At first, we thought he was wearing thin clothes, but later we found that he might sweat even if he wore less. Even when he was sleeping at night, he was very prone to sweating, making the entire pillow very wet. The baby feels very uncomfortable every day. So many people are asking, what is the reason why my 4-month-old baby is always sweating?

It is common for babies to sweat during sleep, and it is not always a symptom of weakness or illness. Many parents believe that their children’s constant sweating is due to their weak constitution. In fact, a considerable number of children suffer from physiological hyperhidrosis. Physiological hyperhidrosis is more common in the head and neck, often occurring within half an hour after falling asleep, and sweating stops in about an hour.

Infants and young children have an active metabolism and are active and lively. Some of them cannot rest even after going to bed at night, so they may sweat on their heads after falling asleep. The so-called physiological hyperhidrosis refers to sweating during sleep when the child is well-developed, healthy, and has no disease. Parents are often accustomed to deciding the best environmental temperature for their children based on their own subjective feelings, and like to cover their babies with more blankets and keep them tightly covered. Because children's brain and nervous system are not yet fully developed and they are in the growth and development period, their body metabolism is very active. Coupled with the stimulation of overheating, they can only regulate normal body temperature by sweating to evaporate the heat in the body. In addition, drinking milk, malted milk or eating chocolate before going to bed can also cause sweating in children. Some parents give their children milk, malted milk, etc. before they go to sleep. After the child falls asleep, the body produces a large amount of heat, which is mainly dissipated through sweating through the skin. In addition, too high room temperature or excessive warmth can also cause children to sweat while sleeping, which are all physiological sweating.

If a 4-month-old baby always sweats on his head, it is probably not due to calcium deficiency. Generally, if there is a calcium deficiency, sweating may occur, especially in the middle of the night. If the indoor temperature is relatively suitable, but sweating still occurs, you can go to the hospital for a blood test to distinguish the cause.
