Effects of Climate Change on Human Nervous System

Scientists point out that the weather has a great influence on human beings. Bad weather can lead to crime, suicide, traffic accidents or let drivers escape. Many people in life think that they have feelings about weather changes. Some people can even feel the coming of dangerous weather in advance, and even children will respond to low-pressure troughs and high-pressure areas.

However, weather itself will not cause physical and mental diseases, it will only aggravate or slow down people's existing injuries.

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 are inattentive and can only drink a small amount of wine. They will react after drinking and drive slowly. 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. According to the survey, about 60% people feel that they are weather-sensitive. Even according to very strict bioclimatology standards, one third of people are sensitive to the weather.

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: drivers overestimate their abilities and misjudge traffic conditions. They hesitate to overtake or overtake at the wrong time. There will also be misunderstandings between drivers and pedestrians.

It is an indisputable fact that the weather has an influence on human beings. The biggest controversy at present is how the weather affects human beings. Professor 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 conditions. The weather has changed and the human body has to adjust accordingly. Because modern people are not used to the natural environment and are far away from nature, 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 It is not clear how a single weather factor affects human beings.

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.
