Ancient saying: “people born with the gas of heaven and earth, the four seasons of the law into”, the natural climate change is affecting the human body all the time, and conform to the changes of the four seasons of the qi, is the principle of Chinese medicine health care. Autumn climate characteristics: wind speed up, humidity drops, early fall heat, late fall cold, day and night temperature difference. All of these will affect us to a certain extent. Lower temperatures in the fall will reduce the secretion of nasal mucosa, the mucous membrane in the nasal cavity has the role of killing airborne bacteria, after the reduction of nasal mucosa, more bacteria will enter the body. In addition the fall air humidity drops, the air tends to be dry. The human body’s optimal relative humidity is: 45% -60%, while the fall air humidity is often less than 40%, dry air will accelerate the loss of water in the body, the mucous membrane in the nasal cavity is more likely to be evaporated, the same will make it easier for bacteria to invade the human body. Secondly, the climate in the fall is also conducive to the reproduction of some bacteria, the humidity of the air in the fall, the climate is suitable for the growth and reproduction of certain viruses, such as enteroviruses, influenza viruses, rhinoviruses, and so on, causing the prevalence of certain diseases. Finally, the increased wind speed in the fall makes the allergic media in the air spread faster. For example, there are a lot of people with asthma in the fall because the large amount of pollen and dust in the air triggers allergies and leads to asthma attacks. Ancient people had very deep and unique insights into the climate and effects of fall on the human body. The Jingyue Encyclopedia says: “If the autumn season is too much, and the golden qi is strong and the wind is from it, then the lungs will suffer from the disease first.” Chinese medicine believes that dryness is the main gas of autumn, dryness and dampness are relative, they represent the two extremes of the amount of moisture in the air, dryness describes the lack of moisture in a dry state. The Laws of Medical Doctrine and Clinics says: “The difference between dryness and dampness is vast. Dry, the gas of the sky; wet, the gas of the earth. Water flow wet, fire on dry, each from its own category, this victory and their negative, the two do not conspire.” Autumn temperature drops, wind speed increases, the lack of moisture in the air, thus appearing in the autumn cool and sharp dry climate. We can experience for ourselves, summer, the day is hot, our body’s orifices open, sweat evaporation, to the fall, cool winds come, our body immediately know, so sweat immediately collected, fluid to the inside, not to the outside vent, often reduce sweat and urine increase, however, if the convergence of too much, so that the surface of our body feel dry, the specific feeling of dry nostrils, dry throat, dry skin. Dry throat, dry skin, etc. That’s why it’s easy to be dry in the fall. But where the fall is not rain for a long time, the climate is dry, it is prone to dry disease. There are several types of high incidence of diseases in the fall, first of all, respiratory diseases, the incidence of colds, asthma, allergic rhinitis in the fall increased significantly. There is an interesting phenomenon that the number of respiratory outpatient visits is directly related to the season. In summer, the respiratory doctor is relatively easy, our hospital’s respiratory department, an average of 200 people a day in the summer to see patients. In the fall, the number of patients increases to 300, and in the winter, when we are busiest, there are about 400 patients per day. Therefore, respiratory diseases are closely related to the change of seasons. In addition, fall is also the season of high incidence of digestive diseases, depression and schizophrenia. The high incidence of coughing in the fall is also related to the dryness of the air. The human body has five organs and six bowels, and dryness is the first thing to attack our lungs. Each part of our body can not leave the nourishment of fluids, such as the respiratory tract will continue to secrete mucus, the digestive tract also has saliva, gastric juice, intestinal fluids moisturizing, the skin continues to secrete sweat and sebum, and even the reproductive system to continue to secrete lubricating fluid, these fluids not only play a lubricating, nourishing role, but also assumed a part of the immune function. The most important characteristic of dryness is to hurt the fluid consumption, will damage the body of these fluids, it can be said that if the fluid deficit, will affect every internal organs and tissues of the human body. There are two types of causes of dryness. As mentioned earlier, wind and heat can accelerate the loss of moisture, while cold can condense moisture and reduce the moisture in the air, so there are two types of causes of dryness. Chinese medicine believes that dryness is divided into hot and cold, fall, there is the summer heat of the residual gas exists, the sense of warm dry; and the winter of cold, the sense of cool dry. Warm dry, mainly in the lunar calendar before 8.15, it is mainly because of the wind and heat to accelerate the loss of moisture in the air, and cool dry produced by the reasons are not the same. Chinese medicine said “dry for the second cold” is cool dry, it is a kind of dry, but it is cold, when violating the human body can affect the lungs to transport the function of water, thus causing a series of dry performance. Common symptoms of warm dryness: heat, headache, dry mouth and throat, throat itching, hoarseness, frequent dry cough. Common symptoms of cool dryness: dry cough without sputum or sputum sparse and small (aggravated by the sight of cold), no sweating, mild cold, dry mouth and throat, tongue pale and not red. The solutions are different for different nature of dryness. The Huangdi Neijing (Yellow Emperor’s Classic of Internal Medicine), Suwen (Su Wen), and Zhi Zhen Yao Da Lun (Treatise on the Essentials of the True Nature) state that “dryness is moisturized by dryness.” The general principle of dealing with dryness is to moisturize. Against warm dryness, there is a more feasible prevention method, is to eat pears. Pear sweet and cold, sweet and moist can nourish the yin, cold can clear the heat of dryness, with the efficacy of moistening the lungs to eliminate dryness. But there are a few points to note on the application method. Herbal Derivatives”: “pear, more food is to move the spleen, less than the disease, with pear meaning, must be discretionary, but the disease of wine and thirst people, food is very good, the end can not but disease.” This passage is to say, pear sweet and cold, the middle jiao deficiency of cold people eat easy to hurt the spleen and stomach, hot and dry evil too much to take only a small amount is not enough to restrain the disease. The only people who like to drink alcohol, internal dryness and heat, heartburn and thirst are the most suitable for consumption, but only as a health care method, if not treated with medication, it is still very difficult to cure the disease. So spleen deficiency loose stool, chronic enteritis, gastric cold disease, cold phlegm cough or external wind-cold cough and diabetic patients avoid eating. Women also avoid eating raw pear after birth. Women have menstrual period and cold dysmenorrhea avoid eating raw pear. For warm dry cough, pear can be used as an auxiliary means of treatment. For cool dryness, the ancients created a classic formula, called apricot suzan, we can simplify it into a dietary health care to prevent cool dryness of a small formula: almond perilla tea. Production method is also very simple: 6g of bitter almonds broken, soaked in water and decocted for 5 minutes, after the water boiled, put a handful of leaves, about 6g, soak for ten minutes, drink tea. The main effect of almonds is to purify the lungs to stop coughing, and at the same time have the function of moisturizing the lungs, while the leaves of Su Ye has the effect of opening and declaring the lungs and dispersing the surface of the cold. The two drugs together, just have the effect of dispersing cold and moistening dryness, can better prevent cold dryness, and even solve some of the symptoms of cold dryness at the beginning of the symptoms. In the fall, there are a few other points to remind you to pay attention to in terms of life health care. In the dry season, it is easy to destroy the normal skin structure by bathing every day. The outermost part of the human skin is the stratum corneum, the automatic shedding of the stratum corneum and the skin sweat mixed with the skin scale will not be a lot, wash off this part properly, the skin has a certain protective effect. If the bath is too hard, the cuticle injury, its role in protecting the skin will be lost, the water in the skin cells is more likely to evaporate, the skin will be more dry. Therefore, into the fall, must change the summer bathing habits, 1-2 times a week is appropriate, specifically according to their own skin sebum secretion level to decide. Bathing should not be frequent use of cleaning products, especially alkaline chemical cleaners, wash after the appropriate application of moisturizing lotion. Autumn many people will feel dry mouth, dry throat, dry eyes, dry skin, humidifier is often the first choice of appliances. Humidifier is indeed to a certain extent, can increase the humidity in the air, so that we feel more comfortable. But the use of humidifiers should also pay attention to the following points: ① the use of humidifiers can not be lazy, should be cleaned every day, change the water, otherwise, the microbes produced in the water emitted into the air will also affect health. ② healthy humidity environment is 45% -65%, in such humidity conditions, the human body feels the most comfortable, a variety of germs are not easy to spread. The use of humidifiers too often, will lead to high air humidity, when the humidity is higher than 65% will make the human respiratory system and mucous membranes produce discomfort, decreased immunity, which leads to viruses take advantage of the situation. So the humidifier can not open a day, according to the demand to decide when to switch. ③ can not directly add tap water to the humidifier. Because tap water contains a variety of minerals, will cause damage to the humidifier’s evaporator, the water contained in the alkali will also affect its service life. Chlorine atoms and microorganisms in tap water may blow into the air with the water mist and cause pollution. If the tap water hardness is high, the humidifier spray water mist contains calcium and magnesium ions, will produce white powder, pollution of indoor air. ④Patients with arthritis should be cautious of using air humidifiers, as humid air can aggravate the condition of arthritis, so it is generally not recommended for use by such patients.
