In summer, the days are long and the nights are short, and Yang energy is strong. People should sleep late and get up early to follow the nature and maintain Yang energy. The Yellow Emperor’s Classic of Internal Medicine states, “In the third month of summer, sleep at night and get up early, without getting tired of the sun.” In summer, people should go to bed later in order to respond to the lack of natural yin energy and get up earlier in order to respond to the abundance of yang energy. Because the sun rises early in summer, the air is fresh in the early morning, you can participate in some outdoor activities after getting up early, and more sunlight during the day, do not hate the long day and the hot day, still insist on participating in labor and physical exercise, in order to adapt to the summer to raise long gas. Due to the summer noon temperature is particularly high, the night sleep time is short, to take a proper nap to relieve fatigue and maintain abundant energy. In terms of clothing, summer clothing to light, thin, soft is good. The better the breathability and heat absorption of the clothing, the more effective it is to help the body dissipate heat, so that people wear comfortable and cool; summer should wear light-colored clothing, it is best to go out with a hat to reduce radiation heat; because of the summer heat and sweat, clothing should be diligently washed and changed, long wear wet clothes, sweat clothes, stimulate the skin, will cause a variety of diseases. Summer heat and humidity win, it is appropriate to prevent sun exposure, reduce room temperature, but not just a momentary pleasure too much to avoid heat and tend to cool, do not sleep outdoors, sleep in a humid place and sit cold stone cold ground. Do not let the fan blow directly when sleeping, air-conditioned rooms, but also to pay attention to the temperature difference between indoor and outdoor not too large, so as not to get cold. It is important to arrange the living room in summer. First of all, we should clean the room comprehensively, the things that should be collected (such as cotton wool, cotton clothes, etc.) should all be included in the cabinet, if possible, to adjust the furniture that affects indoor ventilation, in order to keep the room with enough natural wind. Second, the necessary shading measures should be taken indoors to try to reduce or avoid some heat sources and light; windows should be hung with light-colored curtains for coolness. There is also the room to strengthen disinfection, mosquitoes and flies, to prevent dysentery, typhoid, cholera and other intestinal infectious diseases and the occurrence and prevalence of insect-borne infectious diseases. Second, the diet of the hot summer climate, the human qi and blood tend to body surface, the formation of Yang Qi outside, Yin Qi within the physiological state, people’s digestive function is weak, dietary regimen should focus on clearing heat and heat, strengthen the spleen and benefit the qi. Therefore, the diet should be light and refreshing, easy to digest, and eat less high-fat and thick and spicy things on fire. The principle of summer diet is to eat more bitter and pungent food and less salty food. Bitter flavors such as bitter melon, bitter vegetables, lilies, chrysanthemum, bitter mustard wheat and other foods, beer, coffee, bitter tea and other beverages, help to wake up the brain and refresh, clear the heat; pungent flavors such as onion, garlic, ginger, etc., can improve blood circulation, lower body temperature through sweating, but also regulate the flavor of the diet, stimulate the taste function, enhance appetite.

The summer heat, prevention of summer heat, can eat more watermelon, loquat, peaches and other seasonal fruits, they have good summer heat quenching thirst function. Because of sweating a lot, should drink more water, or consume green bean soup, sour plum soup, red bean soup and other beverages, not only can quench the heat, but also can replenish water and inorganic salts. Appropriate consumption of cold drinks can help the body to dissipate heat, replenish water and play a role in clearing heat and relieving summer heat, but do not eat cold drinks, ice water, cold vegetables, cold melons and fruits because of greed for cold, so as not to damage the spleen and stomach Yang Qi. In addition, the hot and humid climate in summer is very suitable for the growth and reproduction of microorganisms, food is very easy to spoil, so we should pay special attention to dietary hygiene, to keep the “disease from the mouth” of the gate. Do not eat spoiled food, do not drink raw water, raw vegetables and fruits must be washed to prevent the occurrence of intestinal infectious diseases.
