Traditional Chinese medicine believes that people should adapt to the changes in the weather at the turn of spring and summer and focus on their hearts. The heart is yang, which governs yang. Yang of the heart can promote blood circulation and maintain human life activities. Yang-heat qi of the heart not only maintains its own physiological function, but also has a warming effect on the whole body. Water-liquid metabolism and sweat regulation of human body are inseparable from the important role of kaiyang.

In the early days of Xia Zhishi, the qi and blood of the elderly are easy to stagnate and blood vessels are easy to block. Every morning, they can eat a little onion and drink a little wine to promote the circulation of qi and blood, thus preventing the occurrence of heart disease. After the long summer, the weather is getting hotter and the diet should be light. Give priority to foods that are easy to digest and rich in vitamins, and eat less big fish and meat and greasy and spicy foods. After the long summer, the dietary principle is "nourishing yang in spring and summer", and nourishing yang focuses on nourishing the heart, which can not only supplement nutrition, but also strengthen the heart. Eating more vegetables, fruits and coarse grains at ordinary times can increase the supply of cellulose, vitamins B and C and prevent arteriosclerosis. In short, in the long summer season, it is necessary to nourish the heart and nature, make good preparations for summer heat, and make the functions of various organs of the body normal, so as to achieve the state of "sufficient healthy qi and no evil".

Around the long summer [5], the average temperature in most parts of China is 18℃ to 20℃, which is a good season for "all kinds of red flowers and purple flowers". Astronomical experts remind that after the long summer, the weather turns hot, and Chinese medicine believes that "summer heat is easy to hurt gas" and "summer heat is easy to enter the heart". Therefore, at this time, people should pay attention to mental conditioning, strengthen the maintenance of the heart, especially the elderly should consciously carry out mental conditioning, maintain a calm and happy state, and avoid exultation and sadness to avoid sadness and injury.

Long summer solar terms often have thin clothes, so even healthy people should guard against exogenous factors. Once you get sick, don't use antiperspirants easily to avoid sweating and sadness. Old people should pay more attention to avoid stagnation of qi and blood to prevent heart attacks. Therefore, in the long summer season, we should be happy, feel at ease, enjoy ourselves and avoid sudden joy and sadness. Eating a little onion in the morning and drinking a little red wine at dinner can promote blood circulation. Specifically, the diet should be low in fat, low in salt, multi-dimensional and light.
