Pay attention to heatstroke prevention and cooling in summer. (1) Don't eat too many cold drinks or take a cold shower after strenuous exercise. You'd better take a warm bath. (2) When sleeping at night, the air conditioner can be controlled at 28℃. Because at night, people's various physiological functions are at a relatively low level. If the air conditioner is turned on too low, it is easy to catch a cold. (3) Huoxiang Zhengqi series is the first choice to prevent colds in summer. In addition, ten drops of water, cool oil and wind oil essence can also play the role of cool wind and heat. (4) When a child has a cold and fever, there will be a loss of appetite. What parents should pay attention to is that it doesn't matter what children eat. The key is to supplement enough water, because they consume a lot of water when they have a fever, and sweat a lot when they take antipyretics orally, which leads to water loss in the body, which is not conducive to the excretion of toxins. So always give your child porridge or water.
