Excessive sweating is a common phenomenon in children, mostly in young children under 5 years old. The secretion of sweat is regulated by the vegetative nerves. Because children have a strong metabolism, their skin contains more water, the distribution of microvasculature is more, and their autonomic regulation is not sound enough, they sweat more than adults, especially when they fall asleep and sweat profusely, but if the child sweats all night, it is pathological sweating – night sweating. Night sweats are sweating during sleep and stopping after waking up. Usually, children sweat all night long after they fall asleep, even if their blankets are not thick, and often their clothes, pillows, and even bed sheets are wet. This is common in infants with vitamin D deficiency, so timely supplementation of vitamin D and calcium supplements will gradually relieve the sweating. Some children have night sweats due to tuberculosis infection, anemia, fever, malnutrition, and chronic diarrhea. For example, if the sweating is accompanied by low fever, fatigue, poor appetite, flushed cheeks, etc., and if the child is prone to sweating during the day, he or she should be alerted to tuberculosis and should go to the hospital for a chest X-ray or tuberculin test. Give appropriate treatment for the cause and the night sweats will gradually ease. Of course, there are also some children who do not have the above-mentioned causes but also have night sweats, which can be treated by western medicine, so Chinese medicine can take advantage of its unique advantages and regulate them through evidence-based treatment. Physiological sweating does not require treatment, while pathological night sweating should be treated and regulated according to the cause. You should also pay attention to the appropriate outdoor exercise to enhance physical fitness, a balanced diet, do not eat spicy, fatty, roasted products, and actively treat various acute and chronic diseases.
