Pediatric period because of the high metabolism, usually a large amount of activity, especially infants and young children skin water content, the skin surface microvascular distribution more, so the evaporation of water by the skin is also more. In addition, children’s ability to self-regulate hot and cold is relatively poor, even at night also love to sweat, this is a normal phenomenon. The baby sweats a lot, is it normal or disease? Any baby with excessive sweat gland secretion is called excessive sweating. There are two main causes of hyperhidrosis in babies: physiological hyperhidrosis and pathological hyperhidrosis. Physiological hyperhidrosis Most of the baby’s excessive sweating is normal and is medically known as physiological hyperhidrosis. For example, in summer, the hot climate causes children to sweat a lot; when babies and toddlers just fall asleep, the head and neck sweat, and after they fall asleep, sweat decreases; babies sweat a lot after playing, running and jumping, and the general situation is very good; in winter, babies wear too many clothes, the covers are too thick at night, plus the indoor air conditioning temperature is too high, making babies overheat and sweat a lot. Some babies sweating is limited to the head, forehead, commonly known as “steam head”, is also physiological sweating, parents do not need to worry. The baby sweats excessively due to certain diseases, which manifests as a lot of sweating when it is quiet or at night after falling asleep, sweating can wet the pillow, clothes, called “pathological sweating”. Such as infant active rickets, pediatric active tuberculosis, pediatric hypoglycemia, overdose of antipyretic drugs and mental factors, such as excessive excitement, fear, etc. Some babies have endocrine diseases (such as hyperthyroidism), which can also cause pathological sweating. In addition to excessive sweating, each disease has a variety of other disease manifestations, and parents need to take their babies to the hospital for further relevant examinations. 1, active rickets One year old infant sweating, if the lack of outdoor activities do not sunshine, did not add cod liver oil, calcium powder, parents should observe the baby in addition to sweating, whether accompanied by other manifestations of rickets, such as night crying, sleep on the pillow while crying and shaking his head, resulting in the back of the head occipital hair loss ring (see also occipital baldness), ping-pong head (occipital bone at the bone becomes soft, like touching the feeling of ping-pong balls), square skull ( The frontal part of the head protrudes in a square box shape), and the fontanelle is large and closes late. Parents should take the baby to the hospital to ask the doctor to test for a clear diagnosis. 2, pediatric active tuberculosis Babies often not only sweat a lot in the first half of the night, but also sweat a lot in the second half of the night before dawn, called “night sweats”. At the same time, they have poor appetite, low fever in the afternoon (some have high fever), flushed face, loss of weight, and some have cough, enlarged liver and spleen, and enlarged lymph nodes. Often there is a history of tuberculosis exposure, and the elderly, parents or babysitters in the family have tuberculosis. 3, hypoglycemia Often seen in the summer heat, the baby sweats a lot, refuses to eat at night, wakes up early in the morning depressed. The child shows upset, pale, cold sweat, or even sweating profusely, and cold limbs, etc. 4, other pediatric acute and chronic infectious diseases These children can be accompanied by other clinical manifestations: such as typhoid fever, sepsis, rheumatoid disease, connective tissue disease, lupus erythematosus or blood disorders, etc. If the baby is sweating a lot, the mother should first identify the cause. If the sweating is physiological, the mother does not need to worry too much, as long as the external factors that cause the baby to sweat a lot can be removed. The hot summer need to often open the window, the conditions of the electric fan or open air conditioning, pay attention to the wind do not blow directly to the baby, especially after the baby fell asleep, the skin pores open, the body has sweat, the wind blowing directly easy to get cold. More sweat, whether to wear too much cover We advocate that babies wear more clothes than adults, from childhood exercise baby resistance. Some mothers feel the child’s hands cold in winter, they desperately add clothes to the child, wearing several sweaters also wear cotton jacket, cotton pants, cover several quilts at night. You should know that the baby wears or covers too much, so that the baby sweats a lot, the clothes are wet with sweat, and did not change in time, the baby with their own body temperature to cover the wet clothes, but easy to catch a cold and cause a cold, fever and cough. The baby who sweats severely, due to excessive water loss in the body, will cause dehydration. The best way to replenish water is to feed light salt water, because babies, like adults, lose water and a certain amount of electrolytes such as sodium, chlorine and potassium when they sweat. Feeding baby light salt water can replenish water and sodium, chloride and other salts to maintain the electrolyte balance in the body and prevent dehydration that can lead to deficiency. Dry your sweaty baby’s body in time. If you have the conditions, you should give your baby a bath or shower and change your underwear and underwear in time. Babies have delicate skin and excessive sweat accumulation in skin folds such as the neck, armpits and groin can lead to skin ulcers and skin infections. When you find that your baby is sweating a lot, your mother should carefully observe if there are any other complications and go to the hospital in time to treat the diseases that cause excessive sweating. If the infant has active rickets and sweats excessively, go to the hospital, take oral cod liver oil and calcium powder, and do more outdoor activities such as sunbathing. If you suddenly find your child sweating profusely in the early morning of summer, without fever, pale, depressed and with cold limbs, you should consider the possibility of hypoglycemia, feed sugar water at home first and then go to the hospital immediately for further consultation and treatment.
