Why does bad weather make people feel bad?

There is an inseparable relationship between human body and nature. People live in nature, and natural environment and conditions are the material basis for human survival. At the same time, various changes in nature directly or indirectly affect the human body, and the body responds accordingly.

The influence of seasonal climate on human body: the climate is different all year round. High temperature in spring, hot in summer, cool in autumn and cold in winter are the general laws of climate change throughout the year. Under the influence of the regularity of the four seasons, the human body also adapts with different physiological functions. For example, in spring and summer, the yang rises outward, and qi and blood are easy to float on the body surface, so the skin is slack and the human body adjusts by sweating and radiating heat. In autumn and winter, the yang converges and qi and blood are trapped inside, so the skin is dense and sweating is reduced, and the water in the body must be discharged from the stool. Pathologically, the human body will also be affected by natural climate change. When the climate change is too drastic, it exceeds a certain limit of the body's regulatory function, or because the body itself is not sound enough to adapt to external changes, diseases will occur. Such as febrile diseases in spring, fever in summer, dryness in autumn and typhoid fever in winter. Clinically, some diseases, such as joint pain and asthma, are often aggravated when the climate changes suddenly or the solar terms alternate.

Influence of fainting in the morning and evening on human body: Su Wen said: "The gallbladder is full of vitality, but the yang is stronger than the middle, and the yang is weak in the west, and the valve is closed." This shows the diurnal fluctuation of human yang. This is consistent with the daily fluctuation curve of body temperature revealed by modern physiological research, indicating that human function changes rhythmically with the change of day and night cold and temperature. Changes in the morning and evening also have a certain impact on the condition. "Lingshu" pointed out: "People who are sick in their husbands' days are mostly wise, having a good day and staying up late at night. "That is to say, some diseases are mostly mild in the morning and morning, and gradually increase from the afternoon, especially at night. This is due to the diurnal changes of yin and yang and the rise and fall of healthy qi.

Medical meteorologists divide people into three types: the first type is weather reaction type. Under the influence of the weather, they don't feel pain or nausea, but their mood and health fluctuate. The second kind of people are sensitive to the weather, their autonomic nervous system is unstable (not determined by people's subjective will), and their stimulus response to bad weather is stronger and earlier than that of the first kind of people. When the weather changes suddenly, they will feel headache, sleep badly, feel tired, be in a bad mood and get excited easily. They can't concentrate. The third kind of people are sensitive to the weather. These people are usually patients, who may suffer from cardiovascular diseases, rheumatoid arthritis or have suffered from fractures and other injuries. When the weather suddenly turns cold or hot, they may feel the pain of the wound or the aggravation of chronic diseases.

In the case of bad weather, the reaction time of car drivers is slower than usual 10%. In addition, drivers will make the wrong reaction: overestimate their ability and misjudge the traffic situation. Hesitant when overtaking, or overtaking at the wrong moment, there will also be misunderstandings between drivers and pedestrians.

Wolfgang Span, a German medical meteorologist, believes that the influence of weather is the comprehensive influence of temperature, humidity and air pressure on human tissues through human skin, respiratory organs, sensory organs and nervous system. Human tissues and autonomic nervous system make the human body adapt to certain weather. The weather has changed and the human body has to adjust accordingly. Because modern people are far away from nature and unaccustomed to the natural environment, it is difficult for many people to adapt to the sudden change of weather. Primitive people in the Stone Age could only endure all kinds of uncomfortable weather in caves, so they were tempered, while many modern people lived in air-conditioned rooms and felt the filtered weather. In this way, people's bodies can't adapt to the outside weather quickly, that is, blood pressure will rise or fall, pulse will beat too fast or too slow, and sweating too much or too little. Only when they are sick will they arouse people's vigilance

What factors always affect human health? Statistics show that not only so-called ordinary weather effects such as rain, snow, fog and skating will lead to traffic accidents, but also biological weather conditions will greatly affect people's physical and mental health. For example, in areas controlled by high pressure, people can have a good sleep at night. On the contrary, when the high pressure is removed, or the low pressure is moved in and the warm air mass comes, people's sleep is often disturbed. For another example, when the cold air mass comes, the condition of patients with hypotension will be relieved, while patients with rheumatism will feel unbearable pain.
