What are the causes of meteorological diseases?

Meteorological diseases refer to diseases caused by meteorological changes. Sudden weather changes will aggravate the onset and condition of climate diseases. Sudden climate change refers to the drastic changes of meteorological factors such as temperature, air temperature, air pressure and wind power in the human environment. China is a country located in the mid-latitude zone, where the weather changes are easily affected by the "front". The so-called "front" refers to the phenomenon of weather and climate change caused by the intersection of cold and warm air. "Front" mainly appears in late autumn to winter, because the strong cold air and cold wave in the north constantly invade the south and collide with the wet and warm air in the south, thus causing drastic changes in the weather.

Intense "frontal" activities in the climate will lead to nervous system dysfunction in humans and animals, leading to changes in vascular movement response, increased resistance of capillaries and surrounding arterioles, increased adrenaline secretion, increased protein in blood, increased blood viscosity, and increased myocardial burden, thus promoting the onset of cardiovascular diseases, which is why there are many patients with cardiovascular diseases such as hypertension, coronary heart disease and Keshan disease every year.

According to relevant medical reports, the mortality rate of atherosclerotic heart disease is the highest from winter 1 February to the following year1month, especially in the days before and after the "front" climate, which is the peak period of rapid change and aggravation of patients' symptoms. This is mainly because the strong high-pressure climate and severe cold wave fluctuation brought by the "front" stimulate the sharp contraction of human blood vessels, promote the increase of arterial blood pressure, cause severe hypoxia of myocardium and increase the incidence of cardiovascular diseases. In addition, weather changes can easily lead to arthritis, rheumatic pain, colds, bronchitis and other diseases.
