Sports taboo weather

Now the environmental pollution is very serious, and our lives are more threatened than before. Such serious pollution should not be brought into an activity. Every winter's smog, affected by calm weather, will have smog. In winter, the temperature difference between day and night is large, and fog will be produced at night and in the morning, which will have a certain impact on the breathing of the elderly. In spring, the dusty weather in the north will blow your eyes more. The south will be affected by the typhoon next time, and the coastal cities will be destroyed. Don't go out. When the smog index is greater than 200, special people will stop outdoor activities.

The air pollution index is 20 1-300, and the air quality grade is 5, which indicates that the air quality is seriously polluted. At this time, the symptoms of patients with heart disease and lung disease are obviously aggravated, and the exercise endurance is decreased, and the symptoms of healthy people are common. It is suggested that children, the elderly and patients with heart disease and lung disease stay indoors and stop outdoor sports, and the general population should reduce outdoor sports. The value of pm2.5 in the air reaches 75~ 1 15, 1 15~ 150, which is a moderately polluted weather. Generally, outdoor sports should not be carried out in this weather. Smog weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out for morning exercise in foggy days, otherwise it may induce diseases and even myocardial infarction, which may be life-threatening.

It's autumn and winter, when the smog is serious. Small particles suspended in the air are harmful gases, which are harmful to the body once inhaled by people. There is also dusty weather, such as the sandstorm in Nuoda, Inner Mongolia this spring, which is absolutely suffocating. Therefore, it is not recommended to go out in foggy and dusty weather, and it is best to stay indoors!
