It is necessary to nourish yin, tonify yang and strengthen the heart and lungs in summer solstice.

For Xia: Yang has always been a very important link. At this time, many people are seriously greedy for coolness, but it will hurt the yang. So, how should Yang be raised?

Summer solstice health, nourishing yin and strengthening yang, strengthening the heart and lungs.

■ In summer, the sun is shining, nourishing yin and yang and protecting the mind.

In summer, the scorching sun is like fire, and geothermal transpiration. People often only care about immediate comfort, avoiding heat and cold. Watermelon cold drinks are insatiable, so it is better to sleep deeply and feel cold. Some people even braved the sweat to jump into the swimming pool and swim in the cool night. As a result, colds, abdominal pain and diarrhea have mushroomed. So how can we spend the hot summer healthily? Motherland medicine believes that summer health preservation should conform to the characteristics of the prosperity and vigorous growth of all things in nature, focusing on "nourishing yang".

Yang Qi is actually human immunity. Traditional Chinese medicine believes that "yang is the spirit, and exterior defense is the solid." In other words, Yang Can protects the human body, makes people healthy and strong, and avoids the invasion of six evils in nature. "Eight Notes on Respect for Life" says, "Shun Yang can relieve summer heat", and nourishing Yang can help relieve summer heat.

In summer, people sweat a lot, and the yang of the human body is strong outward, including yin, and the yang in the body, especially the spleen and stomach in the middle jiao, is relatively weak. If you don't cover the quilt, or indulge in cold drinks all night, it is bound to use some yang to maintain the balance of yin and yang, which will make the yang damage of the human body more serious. People should not only follow the trend, but also maintain the yang everywhere, and must not let the yang be excessively consumed.

■ Greed is easy to hurt yang, and the diet should be regular.

In hot summer, the outdoor temperature is very high. In order to maintain the balance of body temperature, the thermoregulatory center will expand the capillaries on the body surface, open sweat glands, and constantly dissipate heat and sweat to cool down. Traditional Chinese medicine calls this phenomenon "resolving phlegm and stopping diarrhea, and Wei Yang is not solid". In addition, in the hot summer, people have less sleep, poor appetite, and their body resistance is obviously reduced. If you open the window or turn on the electric fan at night, or sleep outdoors or get cold in the rain, these are very easy to cause summer colds: fever, cough, headache, sore whole body, fatigue and no sweat. Although catching a cold in summer night is not a serious illness, it will make people upset, and sometimes it will be complicated with tonsillitis, tracheitis, arthritis, and even nephritis, rheumatic heart disease and other serious symptoms. Therefore, it is necessary to increase or decrease clothes in time with climate change in summer as in winter; Cover the chest and abdomen with bedding when sleeping at night; Don't take a shower immediately after sweating, dry it immediately after rain, put on dry clothes, or eat some ginger soup.

Avoid overeating and catching cold in diet. Cold drinks, ice cream and iced food must be eaten as little as possible, but some warm food can be eaten appropriately to warm the spleen and stomach yang consumed in the body. On weekdays, people are used to drinking herbal tea to cool off the heat, thinking that drinking more herbal tea can reduce fever and prevent heatstroke. Actually, this is a misunderstanding. Most herbal teas are bitter and cold, and the human body has weak yang in summer. Drinking more will consume the spleen and stomach yang in the body.

■ Summer fire disturbs the heart and is easy to grieve, and it is also necessary to nourish the heart and yang.

All the year round, summer is a fire, and the internal heat communicates with the heart. Fire is Yang, and Yang takes the initiative. Besides, there is fire in the heart. When two fires meet, the mind is easily disturbed and uneasy, resulting in anxiety and irritability. Being upset will make the heart beat faster, which will naturally increase the burden on the heart. As Huangdi Neijing said: "The heart is the foundation of life ... the sun under the sun, and it should be summer weather." Therefore, we should also pay attention to nourishing the heart in summer.

Summer is the easiest time to get upset, so first of all, we should calm down and try our best to keep a peaceful and quiet mind through various channels. Quiet leads to yin, as the saying goes, "calm and cool naturally." After the coordination of yin and yang, the heart is well maintained. At the same time, we must ensure that we are not overworked. The heart is the god of the five internal organs, and its "jurisdiction" is the largest. If you are overworked or depressed, it will damage your heart and lead to the gradual dissipation of yang and harmony. Of course, you can also eat some foods that are pure in heart, such as cooking some delicious lotus seed soup.

Finally, we should pay attention to the normal work and rest in summer, go to bed late and get up early to adapt to the changes in nature. Only by nourishing the yang in spring and summer and making the yang sufficient can we stick to the yin essence in the body and make full preparations for the health care in autumn and winter. As the saying goes, "Yin roots in Yang, and Yang roots in Yin".

■ Assorted pork tenderloin noodles from summer to day, and Changyang tonifies the deficiency and spends the summer skillfully.

In our folk custom, there is a saying that "the winter solstice is in jiaozi's summer solstice", which does have some real significance from the perspective of health preservation. Noodles are long, which the ancients used to describe the longest day of the summer solstice. At the same time, it also tells us that the yang in the human body should be as long as the sunshine on this day. The so-called "long-term care, disease-free, full care, can live a hundred years." So in folklore, we use this long face to imply that the yang of our human body is getting longer and longer, not weaker.

The main component of flour is wheat, which is the food with the highest nutritional value in the whole grain. It "sows in autumn, grows in winter, blooms in spring, and bears fruit in summer", and has the spirit of four seasons neutralization. Cool and sweet, it can nourish the heart and soothe the nerves. It is the best food for patients with heart disease, and is suitable for those who suffer from insomnia, dreaminess, palpitation, yawning and sadness due to deficiency of qi and blood. "Compendium of Materia Medica" also mentioned that "wheat flour supplements deficiency, strengthens the body, thickens the stomach and strengthens the body", which shows that it has been an important food for nourishing the human body since ancient times.

As the saying goes: "Old wheat and new rice", the new wheat is hot, while the old wheat is relatively peaceful, so don't always think that everything is new and good, and the wheat should be old. In addition, most people only eat refined flour, not standard flour. In fact, it is best to mix refined flour with standard flour to avoid malnutrition such as loss of appetite, weakness of limbs and beriberi caused by simply eating refined flour.

We all have the experience of eating noodles. We can't just eat a bowl of white flour. There is always something poured on it, which is used to mix noodles to taste. This kind of thing is called brine in the north and topping in the south. On the day of summer solstice, toppings are also particularly valued. According to some traditional folk surveys, we ancients had a special topping, which was a mixture of chicken and pork.

There is a saying that "the cock crows all over the world". In fact, the sun didn't rise because the rooster crowed, but after the sun rose, the rooster felt the change of time before crowed. Therefore, chickens are the earliest animals that can feel the breath of four seasons and seasons. It has the qi and blood of traditional Chinese medicine, so it is best at nourishing the qi and blood spirit of human body. Chicken is preferably domestic or free-range grass chicken.

Pork is yin and warm, and it is a kind of meat that nourishes yin and moistens dryness. Not as hot as mutton or dog meat, it has a good effect on relieving the constitution of yin deficiency and yang hyperactivity, especially the symptoms we often have in summer, such as irritability, dry mouth, fever with five hearts, burning palms and soles, sweating and so on.

When making toppings, we should pay attention to cutting chicken and pork into strips, that is, chicken fillet and pork fillet. At the same time, put some clean vegetables, such as carrots, yams and potatoes. And cut these things into slender strips, all of which mean "long". This is a comprehensive and nutritious summer solstice healthy diet-summer solstice noodles.

Speaking of the summer diet on the solstice, I have to mention a diet that many young friends especially like now-kebabs with cold beer. On summer nights, the streets and alleys of various cities will become "filled with smoke" and be swept away by barbecues. But from a health point of view, this is a worrying unhealthy diet.

Mutton is warm, and it is even warmer when roasted with charcoal fire. Moreover, when kebabs are roasted, I know that some spicy spices such as fennel, cumin and pepper will be put on them. This makes kebabs very spicy. Drinking cold beer while eating is hot and cold, just like the weather is hot for a while, and it snows for a while, and the human body is most likely to get sick. And when the internal organs suddenly accept the baptism of such an abnormal weather, they will also become overwhelmed.

If you really want to eat mutton kebabs, you can put less seasoning or even less pepper. At the same time, drinking some cool and digestion-promoting tea, such as chrysanthemum tea and cassia seed tea, can not only moisten your throat and quench your thirst, but also help you digest mutton in your body. Summer solstice is the season of high incidence of gastrointestinal diseases and various diseases, and the human body's resistance is also significantly reduced, and the summer heat is more serious. At this time, you must pay attention to the health of your diet and let yourself spend this summer safely.

■ There is a problem with heatstroke prevention from summer to day, and there is no need to open ginger.

The summer solstice is the "pole" of summer, not the "arrival" of summer, which means that the days in the northern hemisphere reach the longest. Summer to the dog days in the future will be the hottest period of the year, and it is very necessary to do a good job in heatstroke prevention at this time. However, our heatstroke prevention work sometimes inevitably has problems. As the saying goes, "it is better to seek medical treatment than to seek for yourself." At this time, we often don't have to rush to find a doctor, but we can find ourselves first.

■ Yin Qi is prone to cold indoors to dispel cold ginger.

Summer is the season with the highest yang. This solar term corresponds to the divination of Zhouyi, and all six hexagrams are Yang, which means that the Yang between heaven and earth reaches the extreme, and then the Yang will gradually disappear and the Yin will gradually grow. At this time, the sun's spirit radiates upward and outward, so the weather is hot, but in summer, it is easy to get cold and cold, so the underground is still quite cold. Connecting with the theory of harmony between man and nature in traditional Chinese medicine, the human body is actually the same. Starting from winter, the qi of human body slowly diverges outward, and diverges to the solstice in summer, which also forms the situation that yang is in the exterior and yin is in the interior. Therefore, Treatise on Febrile Diseases says that "yang is on the exterior and stomach is cold".

However, when the summer sun is like fire and the heat is pressing, people are particularly interested in all kinds of cold drinks and foods in order to cool off the heat. At this time, some cool fruits are in season. If these cold or cold foods are not controlled, it will make cold accumulate in the stomach, damage the yang of the spleen and stomach, and make people feel chills, fatigue, abdominal pain and diarrhea, loss of appetite, sticky mouth and other symptoms. In addition, due to the hot weather, in order to alleviate the heat in summer, many people like to blow air conditioners, and the temperature difference between indoor and outdoor is greatly adjusted. If you don't pay attention, you will catch a cold, so you will be sore all over, stuffy nose, cough and phlegm. We say that these conditions are caused by improper heatstroke prevention, but they are everywhere in real life. At this time, we can use a ginger sugar drink to solve this problem.

Ginger sugar drink, also known as ginger sugar and chopped green onion drink, has this formula in the handbook of Chinese herbal medicine decoction, which requires three raw materials. The recipe is simple: 15g ginger slices, appropriate amount of scallion, 20g brown sugar. First, cut the onion into 3 cm long segments, each with 3 segments. Add 50g water with ginger to boil, and then add brown sugar to the soup for drinking. Take it while it's hot, then sleep under the covers, and you'll soon sweat.

This recipe looks simple, but the effect is very remarkable. Because in addition to the role of scallion in dispelling cold and sweating, we also need to pay special attention to the role of ginger, which is also called ginger. Warm in nature and pungent in taste, it has the effects of dispelling cold and treating cold. Therefore, whether it is cold or cold in the body, you can drink ginger sugar drinks. In addition, from the perspective of five colors, ginger belongs to yellow food. According to the theory of five elements in traditional Chinese medicine, entering the spleen and stomach has the functions of strengthening the spleen and stomach and helping digestion. As the saying goes, "rice is not fragrant and ginger is eaten." Eating a few slices of ginger while eating can not only dispel the cold in the stomach, but also stimulate the appetite.

■ When heatstroke is serious, don't forget to use ginger.

We say that on the one hand, the internal cold and wind-cold cold caused by improper heatstroke prevention in summer solstice season, on the other hand, because this time is not far from the hot day, insufficient heatstroke prevention and cooling measures will lead to heatstroke. Heatstroke is a common disease at this time, not an ordinary wind-heat cold. It can be divided into threatened heatstroke, mild heatstroke and severe heatstroke.

Threatened heatstroke generally refers to symptoms such as dizziness, headache, thirst, sweating, general weakness, palpitation, inattention and uncoordinated movements after patients work in a high temperature environment for a certain period of time.

Some people have severe heatstroke and vomiting symptoms. You can also eat ginger juice to stop vomiting at this time. Peel fresh ginger with a knife, slice it into thin slices, cut it into Suu, chop it into fine powder, put it in a clean container, add vinegar, refined salt, monosodium glutamate and sesame oil, and mix well. Because ginger can mainly cure vomiting, it is called "the holy medicine of vomiting".

People can also use ginger at this time of heatstroke, and even some people faint from heatstroke. Pour a proper amount of ginger juice into the patient's nose, and he will soon wake the patient up. Therefore, Zhu Zeng, a great scholar in the Song Dynasty, once said, "Ginger can enlighten the gods and drive away evil spirits." Enlightening the gods is refreshing, because ginger is a spicy thing, which can enlighten the mind. When enlightening, the blood is smooth and natural.

In fact, ginger has other uses besides the above functions. For example, in summer, many people's feet are sweaty and smelly. You can use ginger slices to soak your feet in hot water in a kettle, and add some salt and vinegar when soaking your feet. You can also use ginger soup to hot compress scapulohumeral periarthritis and other diseases, and you can also drink ginger juice for seasickness and carsickness. As the saying goes, eating radish in winter and ginger in summer keeps the doctor from prescribing medicine. It seems that ginger really plays a big role. As long as we prepare ginger in summer solstice and even in our daily life, some ailments can be solved by ourselves. How do we need to get a prescription from a doctor?

Although ginger is widely used, it is not suitable for people with yin deficiency. Such people are generally characterized by fever of hands and feet, sweaty palms, love to drink water, frequent dry mouth, dry eyes, dry nose, dry skin, upset and irritable, and poor sleep. At the same time, it is not suitable for people with severe internal heat, such as those suffering from lung heat, dry cough, stomach heat, vomiting, bad breath, hemorrhoid bleeding, sores and other diseases.

■ Open the bow left and right, such as shooting a sculpture, which will strengthen the heart and lung disease.

Summer is a sad and lung-consuming season, especially on the solstice of summer, when the sweat is like rain, the heat is unbearable, and the leakage of yang is intensified, and the human body is like a treasury with a deficit. Various diseases, especially those scary "name" diseases, such as coronary heart disease, cerebral hemorrhage, emphysema and so on. At this time, it is making waves unscrupulously. If we don't defend ourselves in time, we are likely to be the target of their rampant practices. Here, I will introduce you to a method to strengthen your heart and lungs-"open your bow left and right like an eagle" to help you pull up this defensive front.

The art of "shooting an eagle like opening a bow from left to right" comes from Ba Duan Brocade, an ancient health preserving technique in China. According to historical records, Baduanjin was quite popular in the Song Dynasty and has a history of more than 800 years. Because this action stretches beautifully, just like a gorgeous brocade, it is named Baduanjin. It * * * consists of eight movements, and "opening the bow left and right like an eagle" is the second.

Chinese medicine believes that the human body is an organic whole. Baduanjin moves muscles through the expansion and contraction of limbs, so as to dredge the meridians of the whole body, thus promoting the operation of viscera and blood, helping the human body to be healthy and strong, and achieving the purpose of eliminating diseases and prolonging life. This set of movements is simple and easy to learn, and the amount of exercise is not large, which is very suitable for the elderly, especially those with weak constitution or some chronic diseases. Specific actions are:

Your feet are naturally separated, your arms are hanging at your sides, and you stand for a moment. Cross your right foot to the right, bend your knees and squat in a standing position, with your thighs as parallel as possible to the ground. At the same time, bend your elbows and slowly lift them on your chest, with your hands clenched and half-lifted, with the tiger's mouth facing up; The index finger and thumb of the right hand are splayed. Visually observe the index finger of the right hand, slowly pull the right hand out and straighten it, turn the head to the right, at the same time make a fist with the left hand, and bend the arm to the left hard, showing a bow and arrow shape; Inhale deeply, adjust breathing 1 ~ 2 seconds, then stand up with your legs, put down your arms, exhale deeply, and restore your initial posture.

Stop for a while and do it again in the opposite direction. Repeat many times.

When practicing this technique, be sure to pay attention to the sinking of shoulders and elbows, keep the upper body upright, and support the heel outside. Never end your shoulders, arch your waist and spread your feet. The five fingers of the side handle should be close together, the flexion should be important, and the shoulders and arms should be flat; The splayed palm side brace should make the shoulders and elbows sink, the wrists and fingers bend vertically, and the palms are empty. Old and infirm people can adjust the height of "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu" or "ma bu", but the movements must be correct and complete. In addition, pay attention to high concentration, breathe naturally, evenly and gently, inhale when pulling the bow, and exhale when restoring. At the beginning of the exercise, you can do 4 movements in each session. After a period of practice, each movement can be gradually increased to about 20 times until you sweat slightly.

The heart is the god of the five internal organs, which controls blood, pumps blood and nourishes the whole body. It ranks first among the five internal organs, just like a monarch, commanding and controlling other internal organs, which, under its unified leadership, perform their respective duties and cooperate with each other. The lung "governs the qi of the whole body", ranking first among the five internal organs and distributing qi and blood of the whole body. The heart, lungs and internal organs play a vital role in human health.

The action of "opening the bow left and right like shooting an eagle" is mainly to enhance the functions of cardiopulmonary breathing and blood circulation by expanding the chest. At the same time, stretching the arms and hands with eight palms can also effectively stimulate the lung meridians distributed in the arms and fingers, adjust the meridians of the Taiyin lung meridians in the hands, and promote the circulation of meridians and qi and blood. Regular practice of this operation can effectively prevent arteriosclerosis, hypertension, coronary heart disease, flatulence, chest tightness, asthma and other diseases caused by cardiopulmonary insufficiency.

At the same time, squatting posture can effectively develop lower limb muscle strength and improve balance and coordination ability; The stretching of the arm increases the strength of the forearm and hand muscles, and improves the flexibility of wrist joints and finger joints; Upper body upright chest expansion is beneficial to correct bad posture such as hunchback and shoulder adduction, and prevent shoulder and neck diseases. In the hot summer, if you can keep exercising in time and persevere, and "bow" several times a day, it is tantamount to buying a long-term insurance for your heart and lungs without paying cash. Why not?

Cherish "Yang Qi"

In hot summer, people either hide in air-conditioned rooms all day or eat special cold drinks, but both methods are unscientific. Traditional Chinese medicine believes that besides heatstroke prevention and cooling, it is also necessary to prevent "summer cooling" in summer, because foods with too low or too cold temperature will damage the yang of the human body, leading to "yin heat" and adversely affect the spleen and stomach.

Be eager for coolness and beware of the invasion of heat.

Now, we mention the word "harmony" more and more. In fact, not only society needs harmony, but also human body needs harmony. To do this, we need to "adapt to the weather" and not "twist into a rope" with nature, because no matter how great human beings are, they can never deviate from their "natural attributes". Since the day when mankind changed from "ape" to "human", just like everything else, there has been a life law of "spring in summer, long harvest in autumn and winter storage". But now, we are deviating from this law more and more.

Wang Qishi pointed out in Xu Li Yuan Jian that "heatstroke prevention in summer, heatstroke prevention and cooling in summer, and dampness prevention in summer." In just a few words, it has become the general program to guide our summer health. It is common sense that it is hot in summer, so it is cool. Why should we prevent "summer cooling"? Because greed and coldness will damage human yang.

Hot summer is always daunting. Modern people often hide in air-conditioned rooms to avoid the heat. In fact, not only we are afraid of heat, but also the ancients are afraid of heat. It was just that there was no modern equipment such as air conditioning at that time. Our ancestors were very clever. They invented the fan. At that time, fans were mostly made of bamboo, which was also called "rocking the wind" or "cool friends" by the ancients. Wealthy families would make fans out of silk, and some literati preferred to write poems on fans to add interest. In the Han dynasty, people also invented a large-scale cooling tool called "impeller fan wind", "one person transports it, and the room is cold." This is a bit similar to the current air conditioner. Some people build "cool houses" based on water. For example, Chengde's "Summer Resort" was specially built by the royal family of the Qing Dynasty for the summer vacation.

It is natural to be cool in summer, but there is a saying in China that "going too far is not enough". If you just want to cool off without restraint, your health may be damaged. Because the cooler the better in summer, too cold may also lead to summer sickness. This may confuse many people a little. I've only heard of people suffering from heat heatstroke, but I've never heard of people suffering from cold heatstroke!

In fact, "heatstroke" has many stresses. Chinese medicine believes that summer heat injury can be divided into yin and yang. What we usually call "heatstroke" belongs to summer heat, which is usually caused by staying in an environment with high humidity, poor ventilation or high humidity for too long. So what is "overcast summer heat"? Traditional Chinese medicine believes that yin and summer heat are "obtained from quietness", "obtained from summer heat and enjoying the cool" or "those who attack people with yin and cold are quick and ignorant". For example, staying in an air-conditioned room for too long, sleeping on the balcony to cool off, or staying in the shade or pavilion for too long may cause headaches, sweating, abdominal pain or joint pain. It can be said that summer is hot because the surrounding environment is too hot, and summer is hot because the environment is too cold. The cause of yin and summer heat is not only summer evil, but also cold evil and damp evil, so it seems to be more "mild" than aggressive heatstroke. The most common symptoms are prolonged symptoms, lingering damp evil, or sweating to reduce fever. For people with yin-heat syndrome, you must never drink mung bean soup to relieve summer heat, otherwise it will only make matters worse. If you want to relieve symptoms, you can drink more ginger and brown sugar water to make yourself sweat and expel the evil of cold and dampness in your body through sweat. In addition, taking Huoxiang Zhengqi Powder also has certain effect.

Eating more cold drinks will also hurt yang.

It's not good to eat too cold except to stay in a place where it can't be too cold. There is a saying in China that "Food is the most important thing for the people". Electric fans, air conditioners and other cooling tools can only cool the body, but the mouth can't stand it. In order to make the mouth "addictive", cold drinks also appeared. It is convenient for us to eat cold drinks now, and ice cream, ice cream and iced drinks emerge one after another. In fact, eating cold drinks is not the patent of modern people, and our ancestors also like to eat cold drinks. However, there was no refrigerator at that time, and rich people usually cut ice and hide in the pit in winter. There were also "ice merchants" in the Tang Dynasty, that is, professional ice collectors, who sold them to people in need in summer. Actually speaking, the birth of ice cream is also related to China. At that time, there was a royal cold drink called "ice cream" in the Yuan Dynasty. Later, this party was brought back to Italy by Kyle Poirot, and later spread to France and Britain. British businessmen transformed it into "ice cream". Eating food small and blindly has become a necessity for people to cool off the heat. In short, people have come up with various ways to escape the heat.

You can eat cold drinks, but you should also pay attention to the degree. Because the relationship between Yin and Yang is unity of opposites, eliminating Yang means that Yin is long, and eliminating Yin means Yang Long. Cold things belong to yin, and yin hurts yang more. Although the human body is vigorous in summer, most of it floats outside. Spleen likes dryness and hates dampness. If you eat more cold drinks, the combination of cold and dampness will damage spleen yang and lead to diarrhea and abdominal pain. Light can also lead to loss of appetite and inability to eat. In summer, people's appetite tends to decline, which is the reason. In fact, it is not only cold drinks, but also some cold foods, such as iced watermelons. It is best to eat less. Watermelon is delicious and juicy, and it can relieve summer heat, so it becomes a must-have fruit in summer. However, watermelon itself is cold. If you put it in the refrigerator again, it will only make things worse. It's strange that it doesn't consume yang. Friends who like to eat watermelon may wish to eat it at room temperature, which will not only cool off the heat but also consume the sun. Especially for some old people and children with bad stomachs, iced watermelons can be avoided.

Of course, it is impossible for everyone not to eat cold drinks at all. In fact, as long as it is controlled within a certain range, it can satisfy the appetite without causing harm to the body. So what is moderation? Generally speaking, it is best not to drink more than one bottle of iced drinks, and not to eat more than two ice cream or ice cream every day. The interval between meals should be more than 2 hours, so as not to burden the spleen and stomach. Old people and children had better not eat cold drinks, so as not to burden the already weak spleen and stomach. You can eat tomatoes or cucumbers at ordinary times. In addition, the common boiled water in life is a good summer drink, suitable for all ages. Don't underestimate boiled water. In traditional Chinese medicine, it has the reputation of "the king of all kinds of medicines". Generally speaking, as long as it is naturally cooled boiled water, it can be drunk, which can not only replenish the water lost due to sweating in time, but also regulate the body temperature and clean the internal environment of the human body, thus achieving the effect of heatstroke prevention and cooling.

To some extent, "harmony" means "balance". There is a saying in Huangdi Neijing that "the origin of life lies in Yin and Yang". The relationship between Yin and Yang is like the beautiful "S" line in Taiji diagram, maintaining a dynamic balance. The task of health preservation is to reconcile yin and yang. The balance of yin and yang is not only the way of keeping in good health, but also the way of living. Only in this way can everything in the world always maintain harmony.
