Summer is the period when the sun is the most vigorous, plants are the most prosperous and animals are the most active in nature. The human body should also correspond to the yang in nature, and "move outward" with the rising of yang, so that its Yang Can can be fully vented and extended. Health preserving methods for strengthening yang in summer: 1. Yang collection: collect external yang to supplement human yang. Make full use of the opportunity of sun-yang exuberance in nature in summer, go outdoors more, get in touch with nature more, absorb the essence of sun-yang, replenish energy and enhance vitality. Although it is very hot in summer, we should not hate the sun too much, but should be properly exposed to the sun. In summer, there are plenty of sunshine and lush trees, which can purify the atmosphere, so there are less organic chemical pollutants such as carbon dioxide and other dust in the air. Therefore, going outdoors in summer, especially in sunny mountain forest areas, is undoubtedly good for health. 2, Yang Shun: That is, to comply with the rising characteristics of the yang, and release the yang from both physical and mental aspects. Mentally, we should be more optimistic and cheerful, maintain a relaxed and open mind, communicate with people more, make our spirit comfortable, vent our emotions and try to avoid getting angry; Physically, we should stretch our muscles, open acupoints, relax our pores, dress loosely and naturally, avoid tying our chests too tightly, and make our Yang Can spread outward, and take part in more beneficial sports activities. In addition, Yang Qi can be supplemented by diet and medicine. 3. Protection of Yang Qi: that is, protecting Yang Qi to prevent the damage of Yang Qi from dissipating too much. Chinese medicine has the saying that the moon should replenish qi in summer. On the one hand, sweating is more in summer, and yang is easy to vent. Sweating is caused by yang transpiration and vaginal fluid, and its process will consume yang. People should not only follow the trend, but also maintain the yang everywhere, do not overuse and overwork, and prevent unnecessary dissipation. In hot summer, people often pay attention to immediate comfort and avoid heat and cold. But at this time, the yang in the human body is exuberant outward, while the yang in the body, especially the spleen and stomach in the middle energizer, is relatively weak, which is the so-called "yin entering", so people should pay attention to protecting the dirty yang in their daily life and diet. If you sleep, you should avoid catching cold in your abdomen, and don't be greedy for cold when you eat. On weekdays, people are used to drinking herbal tea in summer to cool off the heat, and think that drinking more herbal tea can prevent heatstroke and reduce fever. Actually, this is a misunderstanding. Most herbal teas are bitter and cold, and drinking too much will consume the yang of the spleen and stomach. In addition, the yang in the human body is relatively weak in summer, which is more likely to damage the yang in the human body. In other words, we should prevent excessive greed for summer, otherwise it will damage the spirit of the sun. You can also eat some warm food in summer to warm the spleen and stomach yang consumed in the body. 4. Hiding yang and nourishing yin: nourishing yang in summer is also closely related to physical health in autumn and winter, which is the basis of nourishing yin in autumn and winter. Health preservation in summer should conform to the characteristics of prosperity and growth of all things in nature. Nourishing yang in spring and summer can make the yang sufficient, so as to adhere to the yin essence in the body. Zhang Jingyue said in his book "Jing Lei": "Yin originates from Yang, and Yang originates from Yin ... So saints raise Yang in spring and summer, thinking it is the land of autumn and winter ...".
