What are the three months in summer? What are the characteristics of summer climate?

Lead: Summer is the second season in the four seasons of the year, the hottest season in the year, a beautiful festival, a season of changing face and a season of high incidence of many diseases. So, do you know which three months summer is? What are the characteristics of summer climate? The following is what I have carefully prepared, hoping to help everyone!

What are the three months in summer?

Summer is June, July and August. Summer is the second and one of the four seasons in a year. High temperature is the most prominent climate feature in summer, but due to different regions and different dry and wet environments, different climates will be produced, such as hot and dry or wet and rainy. China has a vast territory, and the summer climate in different regions is different. China's southeast monsoon region is hot and rainy in summer, the southwest high altitude region is cool and rainy, and the northwest region is hot and dry.

Spring, long summer, autumn harvest and winter storage are the best seasons for many crops to grow vigorously. Adequate light, suitable temperature and abundant rain provide necessary conditions for plants. Monsoon climate is the main feature of China climate. Summer is affected by the warm and humid air flow from the ocean, which is characterized by high temperature, high humidity and rainy weather. The same period of rain and heat is beneficial to crop growth, and crops have entered a vigorous growth stage in summer.

In the sense of modern climatology (climate average temperature) in China, it is summer when the average temperature exceeds 22 degrees for five consecutive days, and autumn when the average temperature falls below 22 degrees for five consecutive days.

Summer climate characteristics

1, the climate is hot and summer heat is prevalent.

Three months in summer is the time when the yang is the strongest and the yin is the weakest in nature, characterized by long sunshine time, high intensity, the highest temperature, long days and short nights.

Chinese medicine believes that summer heat is the most abundant, so summer heat syndrome and heat syndrome are high. Summer heat belongs to yang evil, and its main symptoms are suppurative diseases such as fever, redness, swelling and heat pain.

In addition, summer heat is also easy to "consume gas and hurt body fluid". "Gas consumption" is mainly manifested in shortness of breath, fatigue, sweating and so on. This is related to the strong sunshine intensity and high temperature in summer, the excessive expansion of skin blood vessels, the increase of blood flow, the decrease of visceral blood flow and the decline of various physiological functions of the human body.

"Injury to body fluid" is mainly manifested as dry mouth and thirst, less urine and dry stool. This is related to excessive sweating in summer and water shortage in different degrees. In summer, people generally feel that physical decline, fatigue, dry mouth and thirst are the consequences of heat, qi and body fluid damage in traditional Chinese medicine.

2. Summer heat leads to heart disease.

Traditional Chinese medicine believes that summer heat is abundant, which leads to a clear increase in heart disease. Studies have shown that high temperature weather can easily lead to the increase of heart rate and blood pressure, which is an important factor to induce or aggravate heart attacks such as angina pectoris, myocardial infarction and cardiac insufficiency.

It should be noted that the heart of traditional Chinese medicine is different from that of modern medicine, which is in charge of blood circulation. The heart of traditional Chinese medicine has two main functions: one is to manage blood vessels, which is in charge of human blood circulation, which is basically the same as the heart function of modern medicine; Second, the temple of the spirit, consciousness and thinking of Master Zang Shen belongs to the function of the brain of Western medicine above his head.

The high temperature and high humidity environment in summer will affect the neuroendocrine system of human body, showing abnormal emotional activities such as irritability and depression, which is related to the heart of traditional Chinese medicine. Therefore, the high incidence of heart disease in summer not only refers to the high incidence of heart disease in western medicine, but also includes mental and nervous system diseases such as insomnia, irritability and depression.

In the long-term life practice, Chinese medicine's understanding of "nourishing the heart and storing it" has penetrated into people's daily life. For example, people usually say what they are thinking, but in fact, the brain is thinking, but Chinese medicine attributes this thinking activity to the heart.

3, rainy, wet syndrome.

There is more and more rain in summer, and the air humidity increases. Proper humidity is beneficial to the growth of animals and plants, so plants grow most vigorously in summer. However, excessive humidity can cause many diseases, which are called "dampness syndrome" by Chinese medicine. There are two common damp syndromes, one is spleen-stomach disease and the other is dermatosis.

Traditional Chinese medicine believes that spleen is characterized by liking dryness and hating dampness, which is most likely to damage its function, such as abdominal distension, loss of appetite, aversion to greasy stool, and even unfavorable urination and edema, which is related to high temperature, high humidity and active bacterial reproduction in summer.

Therefore, summer is the high incidence period of gastroenteritis, hepatitis, cholecystitis and other digestive system diseases, especially the incidence of infectious diseases such as dysentery and viral hepatitis is significantly higher than other seasons. These diseases are related to spleen and stomach and dampness in traditional Chinese medicine, and belong to the category of dampness syndrome in traditional Chinese medicine.

In summer, in addition to humid air, high temperature can also lead to sweating, wet clothes, and long-term wet skin, which can lead to skin diseases such as erosion, nourishing water, mucus and itching. Therefore, skin diseases such as eczema, dermatitis and urticaria will increase in summer. Because the hot and humid environment is conducive to the growth of mold, dermatoses caused by fungal infections such as onychomycosis, athlete's foot and tinea corporis also increased significantly in summer.
