Most moms feel that their babies sweat a lot, especially when they sleep at night. Is it better to sweat a lot? Or is it better to sweat less? This often bothers moms. Baby sleep sweating is divided into physiological sweating and pathological sweating, if it is physiological sweating, baby moms do not have to worry; but if it is pathological sweating, you need to timely treatment. Today we will talk about those things about sweating. Sweat is secreted by sweat glands, and according to the amount of sweat, it can be categorized into hidden sweat and obvious sweat. In occult sweating, the beads of sweat on the surface of the body are not obvious, and in overt sweating, there can be obvious beads of sweat on the skin. One of the main functions of sweating is to regulate the body’s temperature. Body temperature is the temperature emanating from within a person’s body. First, the generation of body temperature and heat dissipation process 1, body temperature generation body temperature is the result of material metabolism. Carbohydrates, lipids and proteins, the three major thermogenic nutrients, through the oxidative decomposition of the energy produced, about 50% into body heat to maintain body temperature, and constantly in the form of heat energy emitted outside the body. 2, the process of heat dissipation skin is the main radiator official, it is mainly through radiation, conduction, convection and evaporation of heat. (1) radiation: is the heat from the surface of an object through the electromagnetic wave to every object surface with which it is not in contact with the way dare heat. Radiation heat accounted for 60%~55% of the total heat dissipation. In the low-temperature environment, it is the main number of heat mode. (2) conduction: is the body’s heat directly to its contact with the colder objects of a way of heat dissipation, conduction dare heat depends on the thermal conductivity of the object in contact, due to the better thermal conductivity of water, clinical use of ice packs, ice caps, cold and wet compresses for hyperthermia patients to cool down, it is the use of the principle of exothermic conduction. (3) convection: a special form of conduction heat dissipation, is a way of heat dissipation through the flow of gas or liquid to exchange heat. (4) evaporation: a way of heat dissipation by liquid to gas, while taking away a large amount of heat. Evaporation accounts for 20%-30% of the total heat dissipation. The human body daily about 300ml of water by the skin in the form of sweating evaporation. When the outside temperature is equal to or higher than the human skin temperature, evaporation becomes the body’s only form of heat dissipation. Second, physiological hyperhidrosis and solutions 1, physiological hyperhidrosis refers to the child is well developed, healthy, without any disease caused by sweating in sleep. Normal children, even if excessive sweating, parents do not need to be nervous: because children’s sweat glands are more developed. The secretion of sweat glands is controlled by the vegetative nerves, and when the child falls asleep, the vagus nerve is excited, resulting in excessive sweating. Sweating is usually more frequent on the head and face, but it is relieved within an hour or two after sleep. Infants and young children due to the metabolism, coupled with the child lively and active, some even after going to bed at night is not restful, so the head can also be sweating after sleep. 2, the solution (1) keep dry and clean sweating more available dry towel in time to dry sweat, to prevent excessive sweating and cold; usually let the child bathe diligently, timely replacement of underwear; bedding or sleeping bag often sun, keep dry and clean. (2) appropriate room temperature infants and young children room temperature 20 ~ 22 ℃, relative humidity 55% ~ 65%, older children room temperature 18 ~ 20 ℃, humidity 55% ~ 65%. Some often accustomed to their own subjective feeling to determine the best environmental temperature of the pediatric, like to give the baby more cover, covered tightly. Children because the brain nervous system development is not yet perfect, but also in the period of growth and development, the body’s metabolism is very vigorous, coupled with the stimulation of overheating, only through sweating, in order to evaporate the body’s heat, to regulate the normal body temperature. (3) do not eat food before going to sleep some parents in the child before going to sleep to drink milk, etc., the body of the child after going to sleep a lot of heat, mainly through the skin to sweat to dissipate heat. Third, pathological sweating and solutions 1, pathological sweating is caused by some kind of disease in the quiet state of the pediatric sweating, especially sweating during sleep. 2, common pathological sweating: (1) rickets manifests itself in the first half of the night after falling asleep, and the pediatric head sweats significantly. As the occipital stimulated by sweat, infants often shake their heads and pillow friction during sleep, resulting in occipital hair thinning, loss, the formation of typical occipital ring hair loss, medically referred to as “occipital baldness”, is the early manifestation of infantile rickets, as long as the timely supplementation of vitamin D and calcium, rickets can be controlled, and the sweating will also be stopped. (2) Tuberculosis (2) tuberculosis, if the child not only sweating in the first half of the night, the second half of the night and before dawn also sweating, most of the manifestations of disease, the most common is tuberculosis. Tuberculosis has other manifestations, such as low-grade fever, fatigue, loss of appetite, flushed cheeks and so on. If you suspect that your child is infected with tuberculosis, you should do lung X-ray or tuberculin test for timely diagnosis and treatment. (3) Excessive sweating is also common in some other diseases accompanied by fever. For example, rheumatic fever, immune diseases, chronic infections and so on. For unexplained excessive sweating, accompanied by growth and developmental stagnation, poor appetite, dreamy and easily frightened, inactive children need timely diagnosis and treatment.
