In early summer, when the temperature is hot and cool, it is important to pay attention to the weather forecast and increase and decrease clothing in time to prevent the invasion of cold and damp evil. During the rainy season in Jiangnan, it is cloudy and rainy, with high humidity and low air pressure, which can easily lead to dampness trapping the spleen, resulting in symptoms such as chest congestion, heavy body and poor appetite. In summer, summer heat is the main qi, and summer heat is a Yang evil that rises and disperses, easily consuming qi and injuring fluid, resulting in symptoms such as fatigue, shortage of breath, lazy speech, thirst and drinking, dry stool and yellow urine. Summer heat, the coup open, the body is most vulnerable to wind, cold and moisture, so summer health should focus on nourishing Yang, not overly greedy cool.

As the temperature rises in summer, the body’s metabolic rate increases, nutrient consumption also increases, a large amount of sweating makes the body lose water and inorganic salts, which can easily lead to water-electrolyte disorders and acid-base imbalance, and can easily cause heatstroke, so it is important to have a reasonable diet, increase nutrition, timely hydration and appropriate salt intake. Adequate consumption of fresh fruit can not only appease the summer heat, but also replenish the loss of water-soluble vitamins and inorganic salts. It is worth mentioning that drinking beverages cannot replace drinking water. The higher the sugar in beverages, the higher the osmotic pressure, which will cause water loss in the body.
