What effect does foggy weather have on health?

Can cell phone radiation and wireless Internet access be harmful to health? In response to the rumors that radiation hurts people, the well-known folk science organization Science Squirrel Society has long published a blog post saying that the general public believes that nuclear radiation and X-rays will harm human health, and large doses and long-term exposure may cause cancer. However, this kind of radiation is essentially different from WiFi radiation. Just like mobile phone radiation, the radiation generated by wireless Internet access is within the safe range, so there is no need to panic. Recently, most areas in central and eastern China are foggy, especially in Beijing, which has brought a lot of inconvenience to people's lives. The low air pressure in foggy days not only affects traffic, but also creates a lot of trouble for people who go out to exercise. Health experts believe that exercising in foggy days may cause respiratory tract and muscle joint damage, and people are advised not to exercise outdoors. The effects of continuous foggy weather on health include: patients with hypertension and coronary heart disease should not take strenuous exercise to avoid inducing angina pectoris and heart failure. More importantly, it is not suitable for exercising in the dense forest in the morning, because trees will release a lot of carbon dioxide at night, with little oxygen content, which is not good for the health. As the saying goes: "Poisonous fog kills the knife in autumn and winter", when the fog rises, the air pressure is low, and pollutants from all directions are difficult to disappear, especially toxic substances such as acid, amine and benzene and pathogenic microorganisms are trapped in it, which is highly concentrated and poses a great threat to human health. Professor Chen, the chief physician of the Department of Pulmonary Diseases of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine, said that smog has the greatest impact on the respiratory system because the nose and mouth are directly connected with the outside world. The air quality is poor and humid, which is conducive to the reproduction of bacteria and viruses, and it is particularly easy to cause the attack or aggravation of respiratory infectious diseases and allergic diseases, such as upper respiratory infection, acute bronchitis, bronchitis, pneumonia, asthma attack, allergic rhinitis and other diseases. Life tips, especially for the elderly, children, patients with chronic diseases and organ transplant patients, have poor immune function and are easily affected by foggy days, thus causing diseases. In addition, persistent fog will increase the burden on the circulatory system of the elderly, which may induce angina pectoris, myocardial infarction and heart failure. And cause pulmonary heart disease in chronic bronchitis. Life Tips Part II: The Harm of Radiation on Wireless Internet to Health: Now people's health awareness is getting higher and higher, so we must clearly understand the harm of radiation to the body. Medically speaking, for a small amount of electromagnetic radiation, the human body's own adjustment ability can completely offset its influence. Even proper electromagnetic radiation is not only harmless to human body, but also beneficial to human body, which is also the working principle of some electromagnetic therapeutic devices.
