Spring returns to the earth, everything recovers, and the climate gets warmer in March, which is the main symbol of spring. However, spring is also a season of changeable climate, especially in early spring, when the climate changes even more, cold currents often attack and the temperature drops suddenly. In daily life, people often say that "spring covers and autumn freezes". The so-called "spring cover" means that you should not take off your cotton-padded clothes too early in spring, but take them off later and reduce them one by one. This is scientific from the weather and climate characteristics in spring and the adaptability of human body to the external environment. Due to the frequent climate changes in spring, hot and cold, windy and dusty, less spring rain, anger and other emotions are easy to stimulate and hurt the liver, and some patients with coronary heart disease are easy to deteriorate. In addition, due to the changes from winter to spring, people's ability to resist diseases and adapt to the climate is weak, and there are more epidemic diseases. If they are not careful, they will get sick. Especially the elderly, the infirm and children, we should pay attention to catching a cold in spring. If they are not properly treated and protected, they often lead to hepatitis. In addition, infectious diseases such as measles, scarlet fever, mumps and epidemic cerebrospinal meningitis are extremely contagious. Motherland medicine also believes that in spring, people with strong liver qi and weak temper should eat less sour food and more sweet food. Because sour taste belongs to the liver and sweet taste belongs to the spleen, we should pay attention to aftercare. In spring, besides paying attention to the above aspects of conditioning, we should also strengthen physical exercise, pay attention to moderate work and rest, improve nutrition according to the characteristics of spring, and enhance physical disease resistance. Summer: Chinese medicine believes that summer is the season when people's hearts are strong and their lungs are weak, so they should go to bed late and get up early. Bitter taste belongs to the heart and spicy taste belongs to the lungs, so you should eat some spicy food in summer. Although the weather is hot, don't be greedy for cold. When sleeping, cover your abdomen with a quilt to avoid catching cold and diarrhea. Avoid the invasion of moisture in rainy season and change clothes in time. Always massage Yongquan point on the soles of your feet, and don't go barefoot to avoid moisture invading from the soles of your feet.
