Baby sweating is a very common phenomenon, almost all babies have had this situation, especially at night when the baby sleeps, sweating is more obvious, sometimes sleep at night without covering things to the baby, the baby is still a sweat, and parents do not feel that the baby is very hot, then the baby sweating is caused by what exactly is the cause of it? In fact, the baby loves to sweat and the baby’s own physiological characteristics inseparable. Because of the rapid growth and development of infants and young children, metabolism is more vigorous than that of adults, the heat and metabolic products produced are relatively more, and infants and young children have more water content in their skin, more microvascular distribution of the skin surface, so more water evaporates from the skin, and again, the baby’s nervous system is not well developed, the ability to self-regulate hot and cold is relatively poor, when sleeping, the sympathetic nerves in charge of sweat glands are usually more excited, so It is easy to understand why babies are prone to sweating at night. In fact, sweating is not necessarily a bad thing, because sweat can take away excess heat and some metabolic products such as uric acid and fatty acids, which is very beneficial to your baby’s health. But if your baby sweats a lot or has other discomforts, it could be a sign of some disease and parents need to pay special attention. So how can we tell if a baby’s sweating is normal? In medicine, sweating is usually divided into physiological sweating and pathological sweating. Physiological sweating Physiological sweating refers to the sweating during sleep caused by a well-developed, healthy child without any disease, which is often seen within half an hour after falling asleep and is dominated by sweating on the forehead, and generally stops slowly within 2 hours after sleeping, mostly in children aged 3 to 7 years old, and gradually disappears with age. At this time the baby sleeps quietly and comfortably, breathing evenly without sound, and sometimes there are some funny expressions on the little face. Physiological sweating is especially seen in active children, who exercise a lot during the day and generate a lot of heat, and the body fails to disperse the excess heat, which is dissipated through sweating after sleep to maintain normal body temperature. In addition, if children drink milk, eat chocolate and other high-calorie foods before going to sleep, the body produces a lot of heat after going to sleep, which can cause children to sweat more at night. In addition, high room temperature, poor ventilation in the bedroom or excessive warmth are also common physiological causes of sweating in children during sleep. Therefore, we should pay attention to reduce the amount of activity during the day, especially before bedtime, pay attention to the ventilation of the room, do not give them a lot of high-calorie food, and increase or decrease the bedding according to the season. Pathological Sweating Pathological sweating means that the body sweats significantly more under the action of certain pathological factors, and usually sweats more than once throughout the night, wetting the pillow and clothes. There are many reasons for pathological sweating, the common reasons are as follows: 1. Infant activity rickets: is the most common reason for pathological sweating, mainly because infants and young children grow faster, caused by vitamin D deficiency in the body. Mostly seen in infants and children under 2 years old. It is usually accompanied by irritability, noisy night, easy to wake up, square cranium, occipital baldness and chicken chest, in addition to excessive night sweating. If you have these symptoms, you can take vitamin D and calcium supplements under the guidance of your doctor. The diet should also include calcium-rich foods such as fish and shrimp. With aggressive treatment, excessive sweating can be corrected quickly. 2. Active tuberculosis: The incidence of tuberculosis has been increasing in recent years. The common symptoms of active tuberculosis in children include cough, low fever, fatigue, loss of appetite, and emaciation. The sweating of the sick child during daytime activities is called false sweating, and the sweating at night is called night sweating, often more than sweating throughout the night. Family members or neighbors may have a history of tuberculosis. If you suspect that your child is infected with tuberculosis, you should go to the hospital promptly and have a lung X-ray, tuberculin test and other related tests. 3. Hypoglycemia: Hypoglycemic sweating often occurs after 12 a.m. until dawn, accompanied by pallor and a weak and fast pulse, which can be corrected by giving the child some sugar water, usually. If the baby has this condition, parents need to pay great attention to it, because serious hypoglycemia can cause the baby to “die quietly” in the early morning. It is necessary to go to the hospital immediately to clarify the cause of hypoglycemia and to diagnose and deal with it in time. In addition, hyperthyroidism, anemia, malnutrition, and overdose of antipyretic drugs can cause pathological sweating, so children with pathological sweating need to be seen in the hospital to check for related diseases. Regardless of whether the sweating is physiological or pathological, parental care is very important. If the child sweats a lot, dry the skin with a dry towel, change clothes in time, and move gently to avoid the child catching a cold. Pay attention to timely replenishment of water and salt. You can supplement oral rehydration salt, or plain water with some salt and sugar. Trace elements are also easily lost when sweating, so it is recommended to supplement trace elements appropriately. Bedding should also be dried frequently, the role of sunlight is not only to heat and dry, but also to disinfect and sterilize. In addition, for children who are weak, planned physical exercises should be carried out to strengthen the body and improve the ability to resist diseases.
