During the long summer solar term, the weather is getting hotter, everything is thriving, and people's physiological state has also changed to a certain extent. Connecting with the heart in summer is beneficial to the physiological activities of the heart. Conforming to the four seasons is the first principle of health preservation. Therefore, we should conform to the changes in solar terms and pay attention to nourishing the heart. Pay attention to long-term health preservation in summer and make a peaceful transition to summer. In the long summer, although summer is coming, the weather is getting hotter and hotter, and the temperature is obviously rising, but it is still cold in the morning and evening, and the temperature difference between day and night is still large. It is necessary to add clothes appropriately in the morning and evening. In addition, when you enter Xia Hou, the days get longer and the nights get shorter. At this time, in line with the changes of yin deficiency in nature, we should also "stay up late" and "get up early" to accept the breath of heaven and earth, but we should still pay attention to "taking a nap", especially taking a proper nap to ensure full mental state and sufficient physical strength. Mental health should also pay attention to "rest" in the long summer. After a long summer, people get excited easily. Therefore, in the long summer, we should "avoid anger and rashness", avoid exultation and great anger, keep quiet, cheerful, relaxed and happy, and always smile. You can also do more quiet cultural and sports activities, such as painting, fishing, calligraphy, playing chess, planting flowers and so on. After long summer exercise, with the temperature rising, people are prone to sweat, and "sweat" is the liquid of the heart. Be careful not to sweat excessively in the long summer season, and drink warm water properly after exercise to replenish body fluids. In the long summer, don't choose too intense sports, but choose relatively peaceful sports, such as Tai Ji Chuan, Taijijian, walking and jogging. In the long summer, it's time for divination. The change in nature is that the yang is getting longer and the yin is getting weaker. Compared with human viscera, the liver is getting weaker and stronger. At this time, the dietary principle is to increase acid and reduce bitterness, tonify kidney and help liver, and regulate stomach qi. At this time, the diet should be light, low in fat, easy to digest, rich in cellulose, and eat more fruits and vegetables and coarse grains. Usually you can eat more fish, chicken, lean meat, beans, sesame, onion, millet, corn, hawthorn, loquat, bayberry, cantaloupe, peach, papaya, tomato and so on. Eat less animal viscera and fat, and eat less salty food such as salted fish and pickles.
