Rain, the 2nd of the 24 solar terms, falls around the 15th day of the first month of the lunar year (February 18-20 on the Gregorian calendar). The sun is located at 330° of yellow longitude. The name Yu Shui (雨水) means two things: first, the weather is warming up and the amount of precipitation is gradually increasing, and second, in the form of precipitation, there is less snow and more rain, which is why it is named Yu Shui (雨水). The rainy season usually starts on February 18 or 19 and ends on March 4 or 5, according to the Gregorian calendar. The “Monthly Rules and Seventy-two Waiting Periods”: “In the middle of the first month, there is water in the sky. Spring is the beginning of the wood, but the wood must be water, so after the spring following the rain. And the east wind is thawed, then scattered for rain.” Meaning, before and after the rainy season, everything began to sprout, spring is coming. Such as in the “Yi Zhou Book” in the rain after the festival, “the geese come”, “grass and trees sprouting” and other weather records. After the “rain”, most of China’s temperature rose to above 0 ℃, the Huanghuai Plain average daily temperature has reached 3 ℃ or so, the average temperature in Jiangnan 5 ℃ up and down, South China temperature above 10 ℃, while the average temperature in northern China is still below 0 ℃. In the rainy season of 15 days, rain to, grass and trees sprouting, we went from the “seven nine” of the sixth day to the “nine nine” of the second day, “seven nine river to open eight nine swallows, nine nine plus one nine plowing oxen all over the place to go”, which means that in addition to the Northwest, the Northeast, Southwest Plateau, most of the region is still in the middle of the winter, many other areas are underway or have completed the transition from winter to spring, in the spring winds and rain, under the urging, the majority of rural areas began to show a sense of spring. The vast countryside began to show a busy scene of spring plowing. Before and after the rain, oilseed rape, winter wheat generally green growth, higher water requirements.” Spring rain is as expensive as oil”, this time the appropriate precipitation on the growth of crops is particularly important. Reasonable “spring cover” rainy season, the northern cold air activity is still very frequent, the weather is changing. Since this season cold air activity is frequent, we can not help but mention the people often say “spring cover”. This is the ancient people according to the characteristics of the spring climate change and put forward the principle of dressing for health. Early spring Yang Qi gradually born, the climate is getting warmer and warmer, people gradually go to cotton to wear a single. But at this time the northern cold, temperature changes, although the rainy season is not as cold as the cold winter months as cold, but because the human skin coupling has become relatively loose, the resistance to wind and cold evil will be weakened, and thus easy to feel the evil and disease. So this time to pay attention to the “spring cover” is a certain reason. This unpredictable weather, easy to cause mood swings, and even disturbed, affecting people’s physical and mental health, high blood pressure, heart disease, asthma patients is even more unfavorable. In order to eliminate these unfavorable factors, in addition to the spring should continue to cover, should take a positive mental conditioning regimen exercise method. Maintain emotional stability has a very important role in physical and mental health. Dietary taboos in the first month should eat less dog meat, mutton, bird meat and other warm products; avoid eating peppercorns, fennel and other hot products, shall not eat raw onions and garlic, peanuts should be boiled should not be fried. This season when the northern diet to congee is good, such as lotus seed congee, Chinese congee, jujube congee, etc.; and the south, especially in the Pearl River Delta area of the diet to soup is good, such as monkey head mushrooms boiled fresh chicken soup, cloud ling and Chinese mountain boiled lean pork soup, spinach rolled slices of beef soup, and so on. It is also desirable when the temperature is wet and cold to stew to nourish the spleen and stomach, such as Cordyceps sinensis stewed duck, brown beans and peanuts stewed chicken feet and so on. Spring climate warming, but also windy and dry, cold in the morning and evening, wind evil gradually increase, often appear skin, mouth and tongue dry, cracked lips and other phenomena, so you should eat more fresh vegetables, juicy fruits to replenish the body’s moisture. As the spring for the beginning of everything, Yang Qi hair over the season, should eat less greasy things, can eat more jujube, Huaishan, lotus seeds, leeks, spinach, citrus, honey, sugar cane, etc., so as not to help the sun leakage, otherwise the liver and wood is too much, it is grams hurt the spleen and earth. Master Tsang’s words During the rainy season, the body’s liver yang, liver fire and liver wind will rise with the spring yang, so special attention should be paid to the liver’s excretion and organization. The natural world is full of vitality, especially in the south where everything is thriving. Nutrition must also be invigorated, vigorous vitality, will be stored in the heart, the body has to do. Rainy season to take into account the characteristics of the function of the spleen and stomach, such as the method of Yang Qi to regulate the spleen and stomach, can use American ginseng, salvia, cassia seeds, white chrysanthemum, and so on. Sun Simiao, a health care expert in the Tang Dynasty, said in “Thousand Gold Formula”, “Spring seventy-two days, save acid and increase sweetness to nourish the spleen and qi”. Five elements in the liver is wood, taste for acid, spleen is earth, taste for sweet, wood over earth. Therefore, the spring diet should be less sour, more sweet, in order to nourish the spleen qi. You can choose parsnip, lily, pea shoots, corns, chestnuts, spring bamboo shoots, yam, lotus root, taro, radish, water chestnuts, sugar cane and so on. The weather before the rain is relatively cold. After the rain, we can clearly feel the footsteps of spring getting clearer and clearer, fragrant flowers, refreshing breath inspire the body and mind. Rainy season, the weather is unpredictable, is one of the most frequent cold wave process throughout the year, this unpredictable weather, it is easy to cause people’s mood fluctuations, and even disturbed, affecting people’s physical and mental health, hypertension, heart disease, asthma patients is even more unfavorable. In the spring, the liver is strong and the spleen is weak, and the spleen is weak, which in turn makes the transportation and digestive functions of the spleen and stomach affected, such as mental depression, abdominal distension and abdominal pain. In order to eliminate these unfavorable factors, in addition to the spring should continue to be covered, should take a positive mental conditioning regimen exercise method. Maintaining emotional stability plays an important role in physical and mental health.
