Recently, a large area of high temperature in the north has rushed into the hot search, with the highest temperature in some areas exceeding 40 ℃. The Beijing Meteorological Observatory issued the first high-temperature orange warning signal of the year, while the Tianjin Meteorological Observatory issued the high-temperature red warning signal on June 16th. Experts suggest that children should pay more attention to their physical health during hot weather to avoid heatstroke, gastrointestinal diseases, etc. Wang Lijing, the head of the emergency department at Tianjin Children's Hospital, introduced that under continuous high temperatures, the number of children seeking emergency treatment at the hospital began to slightly increase. The most common health problem for children caused by high temperatures is heatstroke. Generally manifested as dizziness, headache, flushing, thirst, excessive sweating, and even fatigue, fatigue, decreased judgment, nausea and vomiting, diarrhea, and in extreme cases, heat stroke may occur. Wang Lijing suggests that in hot weather, children should try to avoid engaging in outdoor activities for long periods of time in strong sunlight. When going out, they should be well protected from sun and replenished with water in a timely manner. In addition, parents should be careful not to leave their children alone in the car during hot weather. Gastrointestinal diseases are also a common disease in children with high temperatures. Wang Lijing said that children like to drink iced drinks because they eat more raw fruits and vegetables in summer, and the possibility of Food spoilage is also increasing, which may lead to diarrhea. It is recommended to pay attention to diet, maintain hygiene, and seek medical attention in a timely manner based on the condition of children's gastrointestinal diseases. In addition, hand, foot, and mouth disease is a common infectious disease in summer. Wang Lijing introduced that after infection with hand, foot, and mouth disease, the patient is mainly characterized by fever and rash on the hands, feet, mouth, and buttocks. Within one week after the onset of the disease, the transmission is strong. It is recommended to wash hands and eat cooked food frequently, ventilate the home, clean and disinfect children's tableware, toys and other items, and try to avoid taking children to public places where people gather and the air circulation is not smooth. Wang Lijing also reminded that when blowing air conditioning in hot and cool weather, it is important to avoid setting the air conditioning temperature too low, especially when children are present. It is recommended to set the air conditioning temperature at around 26 ℃ to 28 ℃ and open windows for ventilation for 15 to 20 minutes every two to three hours. (Outlook New Era Network)
