Spring, summer, autumn and winter are related.

The normal laws of climate change throughout the year are spring temperature, summer heat, autumn dryness and winter cold. Under the influence of climate change in four seasons, all creatures in nature will inevitably change accordingly, which is the natural law of Tibet in spring, summer, autumn and winter. The physiological function of the human body is also in line with nature. If the metabolism of the body violates this law all the year round, the qi of the four seasons will hurt the five internal organs, that is, "cold in spring, heat in summer, dampness in autumn and typhoid in winter". Su Wen's Four Qi Tunes the Spirit says: "The four seasons of Yin and Yang are the foundation of all things and the foundation of life and death. If you go against it, it will be a disaster. If you go against it, you will not get sick. It is the Tao. " This further shows that human health is closely related to climate change in four seasons.

Climatic characteristics of four seasons and physiological characteristics of human body

When it comes to how people live a long life, Huangdi Neijing clearly points out that "the health of the wise-they must follow the four seasons and go against the cold and heat."

It is an important idea of Chinese medicine to keep healthy and prolong life by observing the law of the growth and decline of Yin and Yang in spring, summer, autumn and winter and adapting to the climate change in a year of cold and summer. As an important part of diet health, different dietary principles and requirements should be determined according to the climatic characteristics of different seasons and the physiological and pathological characteristics of human body.

Climatic characteristics in spring and physiological characteristics of human body

Spring refers to the period from beginning of spring to long summer in China lunar calendar, that is, January, February and March of the lunar calendar, including six solar terms: beginning of spring, Rain, Surprise, Equinox, Qingming and Grain Rain. Its climate is characterized by warmth and humidity. When spring returns to the earth, the yang of nature begins to sprout and everything recovers, bringing a thriving scene. All living things in nature grow rapidly. However, there are some harmful things, such as pathogenic microorganisms, bacteria, viruses and so on. , will also take advantage. All kinds of diseases and insect pests are rampant, which has brought great disasters to people, especially in southern China. Nevertheless, spring is still the season that brings vitality to everything. When the yang in nature begins to grow, "man corresponds to heaven and earth", at this time, the yang in the human body also diverges upward and outward in line with nature, and its physiological changes are mainly reflected in the following points: First, the activity of qi and blood is strengthened, and metabolism begins to flourish. Second, the liver governs spring, and the liver qi begins to flourish. Due to the mild climate, people's outdoor activities are gradually increasing, so the blood stored in the liver flows to the limbs. In spring, with the warming of the climate and the increase of outdoor activities, people's spiritual activities begin to become active. These physiological changes put forward new requirements for diet and nutrition in spring.

Climatic characteristics and human physiological characteristics in summer

Summer refers to the period from Long Summer to beginning of autumn, that is, April, May and June of the lunar calendar, including Long Summer, Xiaoman, Mangzhong, Summer Solstice, Slight Summer and Great Summer. The climate in summer is characterized by heat, and hot summer is a steaming season. In order to adapt to the changes in nature, human beings have formed the ability to recognize the changes in the external environment in the long process of evolution, and can automatically adjust their physiological activities to adapt to the changes in the environment. Its physiological changes are mainly reflected in the following points: First, qi and blood run vigorously, and yang qi dominates in summer, which is the extreme of yang rising. Yang is abundant, the temperature is high, and it is full of exterior and interior, and the human body has yang flowing smoothly, and qi and blood tend to the body surface. Second, the body fluid leaks out, and it is hot in summer, so the human body is easy to open and drain, and the amount of sweating (sweat refers to the liquid discharged from sweat holes after the body fluid evaporates through the evaporation of Yang) is much greater than that in other seasons. Third, the heart is connected with summer, and the human heart corresponds to summer. In summer, the physiological function of the heart is relatively strong, which is manifested as the main blood vessel of the heart, full of qi and blood, smooth exercise, increased sweat excretion, full of yang, floating outside, strengthened functional activities and full of energy. Therefore, in order to have a better diet in summer, we must grasp the relationship between seasons and viscera, replenish the energy consumed by the heart purposefully in summer for three months, and protect the heart.

Climatic characteristics in autumn and physiological characteristics of human body

Autumn refers to the period from beginning of autumn to beginning of winter, that is, July, August and September of the lunar calendar, including the six solar terms of beginning of autumn, first summer, white dew, autumnal equinox, cold dew and first frost. The climate in autumn is mainly dry, and people often describe it as "crisp in autumn" and "windy and dry". Autumn is a season of golden breeze and pleasant climate. This is because people have just spent the hot summer, and whenever the cool breeze blows, they feel clear-headed and refreshed. However, due to the continuous convergence of its weather, the air lacks moisture and becomes a cold climate. At this time, people often feel dry mouth and nose, thirst, dry skin and even dry stool. Therefore, people often compare the dryness in early autumn to "autumn tiger", which means that dryness is easy to hurt people. Due to the climate characteristics in autumn, we can not only see all kinds of diseases caused by dryness, but also see all kinds of diseases caused by dampness in summer, laying the foundation for common chronic diseases in winter. Therefore, in the autumn diet, we must choose the corresponding diet according to the changing characteristics of heaven and earth and the physiological characteristics of human body.

Winter climate characteristics and human physiological characteristics

Winter begins in beginning of winter in the lunar calendar and ends in beginning of spring in the following year. Including beginning of winter, light snow, heavy snow, winter solstice, slight cold and severe cold, namely 10, 12 of the lunar calendar. The climate in winter is mainly cold. Winter is the season when everything is hidden. At this time, it is freezing, everything is dying, and it is a depression scene. Most people relatively reduce outdoor activities, go to bed early and get up early; Add more clothes and quilts at ordinary times to avoid being attacked by cold waves. Therefore, due to the cold climate in winter, people are prone to various diseases caused by wind and cold. In winter, when the cold is in season, the human body's yang gathers, the qi and blood tend to flow inward, the skin is dense, and water and dampness cannot leak from the body surface. After the kidney and bladder are gasified, a small part of them become body fluid all over the body, most of them become water, and the bladder becomes urine, which invisibly increases the burden on the kidney. So, in winter. Nephritis, pyelonephritis, enuresis, urinary incontinence, edema and other diseases are easy to recur or aggravate. Winter is dominated by cold. If people can't add clothes and quilts in time, their resistance will decline, the functions of organs such as heart, stomach and lungs will be disordered, and even diseases such as tracheitis, stomachache and coronary heart disease will recur, and diseases such as colds, joint pain, cough and rheumatic joint hypertension will occur or worsen.
