What should we pay attention to when the weather is wet in Guangdong in spring?

For several days last week, the whole of Guangzhou was shrouded in gray, hot and humid air. According to the meteorological department, this kind of weather is called "smog weather", which often appears whenever there is an inversion, which has a certain relationship with air pollution. Due to the decrease of air pressure, the inhalable attached particles in the air suddenly increase, and the air mobility is not good, which leads to the increase of virus concentration in the air, and the human respiratory system is first affected. Liang, director of the internal medicine clinic of the First Hospital of Sun Yat-sen University, said that recently, patients with respiratory diseases in the internal medicine clinic accounted for14, with asthma, emphysema, bronchitis, rhinitis and various respiratory infections as the majority. At the same time, poor air quality is also an important factor to stimulate the recurrence of chronic diseases, such as chronic bronchitis, asthma, tracheal dilatation, bleeding, etc., which are obviously related to the weather. Psychologists also said that people with poor psychological quality are also prone to induce some psychological obstacles, such as depression, because of the turbid air. Patients with respiratory diseases should be careful. Studies have shown that many seasonal diseases are closely related to changes in weather and climate. Atmospheric pressure, temperature, humidity, sunshine, wind and other meteorological factors will affect people's physiological functions and cause emotional changes. For example, the higher the air pressure, the greater the ability of blood to dissolve oxygen; The lower the air pressure, the lower the ability of hemoglobin to bind oxygen in human body. If the air pressure changes too much and too fast, it will cause hypoxia symptoms such as rapid heartbeat and shortness of breath. This physiological change will cause emotional tension and irritability. It can be seen that the weather has gradually become a factor affecting people's physical and mental health. Intervening some inducing factors according to weather changes is helpful to the prevention of diseases. Serious respiratory diseases such as tracheitis, bronchitis, pneumonia, lung abscess, tuberculosis and bronchial asthma are sensitive to the living environment. Among many environmental factors, air humidity has the greatest influence on lower respiratory diseases. In the rainy season in the south, humid weather is most suitable for mold growth, which often leads to the aggravation of respiratory diseases. Beware of the recurrence of chronic diseases As the saying goes, "A hundred herbs sprout and all diseases break out", which means that people suffering from chronic diseases should be careful of the recurrence of old diseases in spring. Especially around the vernal equinox, patients with chronic diseases are most prone to relapse, such as migraine, stomachache, chronic pharyngitis, allergic asthma, hypertension, coronary heart disease, myocardial infarction and psychosis. For the above diseases, self-regulation should be done before the onset, and mental, daily life, diet and exercise health care should be done well. For example, don't be overworked, pay attention to conserve physical strength, get enough sleep, especially when sweating, don't blow, and beware of foreign evils invading the body. The temperature difference between day and night is large and it is easy to catch a cold. The weather in Guangdong is very strange now. Wear short sleeves at noon, and a coat is hot enough in the morning and evening. This morning, the temperature difference between day and night was 7-8℃, which made it difficult for people to adjust their temperature. In addition, people don't pay attention to keep warm, and ladies who wear winter clothes put on beautiful dresses early, which is easy to catch cold and cause colds. The doctor pointed out that if the temperature is lower than 17℃, people need to wear appropriate clothes to adapt to the environment, otherwise they will suffer from diseases such as colds and rheumatism. Cold will also reduce the body's resistance and damage the immune system function. Therefore, it is necessary to avoid poor self-protection ability and thin clothes. You can keep abreast of the weather changes according to the weather forecast, and pay attention to bringing an extra coat for backup. Intimate tip: don't go out to exercise in foggy days, especially fog has many adverse effects on human health. Because many infectious diseases, such as whooping cough, influenza, chickenpox and measles virus are spread by droplets in the air, some bacterial eggs can float in the fog, so fog is the transmission medium of many infectious diseases. In the fog, because the relative humidity is too high, it will affect the normal secretion of endocrine glands in the human body, because it will accelerate blood circulation during exercise, and the human body will more easily absorb various germs in the fog. Many people will feel inexplicably tired, bored and depressed in foggy days, and their temper will easily become anxious. In addition, urban air pollution is serious. When there is fog in the morning, the pollutants in the air cannot spread to the sky, so that the concentration of pollutants in the near-earth air reaches the maximum. Therefore, exercise in foggy days can not only improve physical fitness, but also affect people's health.
