Tomb-Sweeping Day, Dragon Boat Festival, Spring Festival and Mid-Autumn Festival are also called the four traditional festivals in China. At first, Tomb-Sweeping Day was just the name of a solar term. Later, it merged with the Cold Food Festival and evolved into a day to worship ancestors and sweep graves. "Fifteen days after the vernal equinox, the bucket refers to Ding, which is used for Qingming. When everything is clean and bright, everything is clean and bright when it is covered, hence the name." Because the custom of cold food in Tomb-Sweeping Day pays attention to forbidding fire and cold. Tomb-Sweeping Day, also known as the outing festival, goes out for an outing to offer sacrifices, which not only shows respect for the deceased, but also shows joy for life. "Huainanzi Astronomical Training" in the Western Han Dynasty: "Qingming comes". Qingming wind, that is, fresh and clear wind, when the weather is sunny and warm, the vegetation in northern China begins to turn green. The clean and bright scenery replaces the cold winter scene of withered plants, bleak everything and sunset. For a year's physical and mental health, Qingming is not only a sign of spring health (you should be pure and clear at this time), but also the core period of nourishing Yang in spring and summer. From Qingming and Grain Rain, marked by 15 days, it can be said that it is of great significance to raise yang. Let's talk about the reasons.

Let's talk about the influence of Qingming phenological environment on people.

Qingming is between the vernal equinox and Grain Rain, and it is clear and rainy. Qingming means clean and bright, the temperature warms up, and the vegetation begins to flourish; As the saying goes, "Snow breaks in Qingming Festival and frost breaks in Grain Rain". Grain Rain means "Rain gives birth to a hundred valleys". On clear and rainy days, Grain Rain is conducive to crop growth. Before and after Tomb-Sweeping Day, it was a critical period when the temperature rose and everything flourished. What does everything need to grow? Nature is the rain that moistens everything. From this point of view, it is also the scheduled arrangement of nature that there are many rains during the Qingming period. Besides the rainy season, you will also see the problem of "catching a cold". This is because the weather is easy to be cold and hot, sunny and rainy; Coupled with the large temperature difference between morning and evening, if you don't increase or decrease your clothes in time at this time, your body is not healthy, your yang is weak, and you can't warm yourself, so you are prone to catch a cold. Coupled with the increase in rain, humid air is conducive to the breeding of various bacteria and viruses, and the epidemic situation, including many exogenous diseases, will also increase. In addition, rainy weather, combined with the atmosphere of "missing the old friend" and "missing the sad" in Tomb-Sweeping Day, will occasionally make people's psychological state depressed and depressed, affect people's resistance, and also lead to colds and colds.

It is easy to hurt the spleen and stomach when it is sunny, rainy and wet, and the spleen and stomach have the function of transporting water and dampness. Therefore, the spleen and stomach should be nursed back to health. Regulating the spleen and stomach requires not only food supplement, but also emotional adjustment and moderate exercise. Although the rainy season will affect outdoor activities, it will also have an impact on health care. But it's best to keep exercising, but be sure to keep warm and clean during exercise and after sweating to avoid sweating and catching a cold.

Generally speaking, there is wind and rain in Qingming Festival, which will have an impact on people's health, but the nature of wind and rain at this time is still different from that in autumn and winter, which we will talk about later.

What is the significance of Tomb-Sweeping Day Qi for health preservation?

In addition to the general spring health goal, the key health goal of Tomb-Sweeping Day is to prevent cold and humidity. Qingming health care mainly pays attention to preventing colds. Chinese medicine believes that "the combination of pathogenic factors leads to qi deficiency". Healthy qi is weak, and it is easy to feel exogenous pathogens and catch a cold. Only when the vital qi is abundant, the human body's qi and blood are smooth and the yin and yang are balanced can we resist the invasion of cold and viruses. This vital qi of traditional Chinese medicine is the ability to resist diseases and recover, which is equivalent to what we call immunity. Therefore, preventing colds requires keeping healthy qi. There is a classic prescription in Chinese medicine called Yupingfeng Powder. Listening to this name is to build a barrier for the body by nourishing healthy qi and prevent exogenous diseases. Of course, there are many ways to keep healthy qi. In addition to traditional Chinese medicine methods such as diet and medicine, we should also avoid fatigue and live regularly. Physical fatigue is also one of the reasons for the high incidence of colds. Being tired outside, "wasting energy", being weak in vital qi, and being vulnerable to viruses can lead to colds. From the perspective of modern health care, all kinds of methods to enhance immunity, including nutrition and exercise, can be classified into the categories of being clear, keeping healthy qi and preventing colds.

Besides preventing colds, it rains more and more in Qingming to Grain Rain. If the rainfall exceeds the normal level, it belongs to the "dampness evil" of traditional Chinese medicine, which is a cause. In order to prevent moisture from invading the body and avoid symptoms such as shoulder and neck pain, joint pain, abdominal distension, and reluctance to eat, the first thing Qingming should do is "avoid". With the increase of rainfall, it is best to take an umbrella when going out to avoid wading in the rain. Wet clothes are wrapped around the body, which is caused by cold and dampness. If you accidentally feel moisture, get rid of it in time. Feel the external dampness, and the evil is not deep, which can be explained from the exterior. For example, drink a cup of warm brown sugar ginger jujube tea, soak a warm foot and sweat slightly to get rid of external dampness. Also be careful not to live in a humid place for a long time; Even if you don't open the window often in wet and rainy days, make sure to wear dry clothes; Chinese medicine believes that dampness is often accompanied by "wind" and "cold". In addition to wind protection, be careful not to eat too cold food. We should eat more foods that strengthen the spleen and stomach, and dispel dampness, and properly warm them up to facilitate urine excretion and promote water-dampness metabolism. If the weather is fine, you should go out to bask in the sun more, exercise properly, and use yang to dissolve the moisture.

Enlightenment of ancient Qingming health-keeping custom on today's health care

First, there are many ways to prevent exogenous diseases and allergies. The ancients believed that the weather changed frequently during the Qingming period, which was easy to induce exogenous diseases (including epidemics). The ancients used the method of medicated bath on the occasion of Qingming. "The Witch of Zhou Li Chun Guan" contains: "Witches don't take a bath when they are old." Zheng Xuan's annotation is: "Twenty years old was removed, and now it seems like March. Bathing is bathing with fragrant herbs. " Today, there are still fitness methods of bathing with flowers and plants in some folk places. Tomb-Sweeping Day is the time for pollen to spread. After pollen floats in the air and is inhaled, symptoms such as nasal congestion, runny nose, sneezing, nasal cavity and itching all over the body often appear. Therefore, it is suggested that people with acute illness, weak body or allergic constitution should go hiking as little as possible and avoid direct contact with plants that are easy to induce allergic symptoms.

The second is to conform to nature, and spring is no longer hidden. Due to the rain, the temperature difference between Qingming morning and noon is large, so pay attention to keep warm. But after Tomb-Sweeping Day, we should also pay attention to the "spring cover". If the temperature exceeds 15 degrees Celsius, you should reduce your clothes and stop covering. Especially when the internal heat of the Qingming human body meets the external moisture, it is easy to get sick. Therefore, wearing a hat can be reduced, and you must not let your body sweat when exercising. Especially for children with fast metabolism and strong yang, if excessive "spring covering" is carried out, it will lead to the intersection of internal heat and external evil, and induce diseases such as colds and excessive internal heat, and even respiratory infections and skin bleeding. Usually, people with excessive liver yang will not only have asthma, but also people with high blood pressure will have headaches, dizziness, blindness and even stroke. Therefore, in line with the natural growth trend of yang, it is not necessary to stick to the custom of hiding in spring.

Third, the Qingming Festival is the end of spring, so the diet should be light, and it is not advisable to eat big, hot, fried, fatty and sweet products. Eat more seasonal vegetables, as well as mushrooms, black fungus and other foods that are conducive to enhancing immunity, and also have the significance of preventing colds and eliminating dampness. You can drink mung bean soup, red bean soup, sour plum soup and green tea to prevent heat accumulation in the body. Don't eat mutton, dog meat, spicy hot pot, pepper, pepper and other spicy products, eat less and eat more meals, don't overeat, eat less spicy, salty, oily, sweet and other irritating foods to prevent pathogenic heat from turning into fire and inducing diseases such as sores, furuncles and swelling.
