Summer fever is a unique disease in infancy and early childhood, characterized by prolonged fever, thirst, excessive urination, and closed or low sweating in summer, and the symptoms may subside naturally after autumn cool. The cause of the disease is generally believed to be hot temperatures, dysfunction of the thermoregulatory center, and reduced or lack of sweat gland secretion. I. Why does heat stroke occur in infants After 6 months of age, infants have increased activity, higher metabolic rate, and increased heat production. However, the development of the central nervous system is still immature and the sweat glands are underdeveloped, so they sweat less and do not dissipate heat easily. For the above reasons, in the hot summer, especially in the southern and central regions, it is often a very hot summer and the weather is unusually hot, especially when the climate is sultry and there is no trace of cool breeze, if parents do not pay attention to the child to avoid the heat, the infant may have the possibility of heat stroke. What are the manifestations of summer fever? Summer fever mostly occurs in infants from 6 months to 3 years old. 1, fever The main performance is irregular long-term fever, body temperature fluctuates from 38 to 40 ℃, fever characteristics are: the higher the temperature and the climate: the higher the temperature, the higher the child’s body temperature; the hotter the weather, the higher the child’s body temperature; the weather is slightly cooler, the child’s body temperature has dropped. High fever without sweat: Although the child’s body temperature is high, there is not much sweat around the body, and there may be only a slight sweat on the forehead, which can be said to be a dry fever. 2. Thirst, excessive drinking and urination When the body temperature is high, the child may drink more than 1,000 ml of water a day and urinate up to 20 times or more. Even with this drinking, the child’s mouth and lips are dry. If the child is not given water, the infant may become irritable and restless. 3.The disease resembles a cold at the beginning of the disease The initial symptoms of the disease resemble a cold, such as runny nose, sneezing and nasal congestion. 4.Other manifestations When the body temperature is too high, there may be drowsiness, jumping and other symptoms; when the fever is too long, there may be indigestion, reduced appetite, pale face, lethargy and weakness and other symptoms. Although the fever does not subside, there may be no abnormal findings during blood, urine, stool and chest X-ray examinations at the hospital. Some lymphocytes may be mildly elevated. Third, the care of summer fever A few children can have summer fever for 2 or 3 consecutive summers, but the symptoms will decrease year by year. Therefore, if your child has heat stroke this year, your mother can take some precautions before the coming summer. You can give your child some herbal medicine to prevent heat stroke and move your child to a cooler area if possible. Heat stroke can last for 1 or 2 months. In hot climates, it can last for 3 or 4 months. Therefore, it is very important for parents to take careful care of their children during the fever period. In principle, do not use antipyretic drugs. If the child is breastfed, do not interrupt breast milk during this period. Give the child a protein-rich, easily digestible, calorie-rich and nutritious diet. Ventilate the room. Give your child a warm bath every day, with the water temperature 3 to 4°C lower than the child’s body temperature. Soak in the bath for 20-30 minutes at a time, with relatively more water. But pay attention to safety, do not let the water pour into the child’s mouth and ears. Must not just let the child play in the water by themselves, adults can not leave the child.
