According to the observation of the ancients, the intense heat has three phenological characteristics. They are the first warm wind, the second cricket and the third eagle. In June of the lunar calendar, crickets also leave the fields and hide in the corner for the summer. Because of the high ground temperature, the eagle was forced to hover at a refreshing altitude. The ancients believed that there would be no relaxation without a gentle wind.
There is a cloud in Huangdi Neijing: "The health of the wise must also be suitable for four seasons of cold and heat, comfortable and comfortable." Bing Wang said, "Yang is full of heat, but it can't control the cold. Being sick is summer heat. " The summer heat mentioned here is "heatstroke"
For manual workers and outdoor workers, if they want to prevent heatstroke, they should drink plenty of water, take a small amount of Ren Dan at the same time, and often drink summer drinks such as mung bean soup. If you have cardiovascular and cerebrovascular diseases, you should ensure adequate sleep and strengthen indoor ventilation, especially in sultry weather. Patients with gastrointestinal diseases should pay attention to diet rules, don't overeat, pay attention to food hygiene and prevent intestinal infectious diseases. At the same time, we should eat less cold things to avoid aggravating the illness.
When water vapor rises in summer, dampness is easily trapped in the spleen and stomach. Therefore, the diet should be based on light tonic to avoid excessive consumption of spicy and greasy food.
