Why is rheumatism affected by the weather?

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.

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.

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.
