Weather-trained

I don't think we should do morning exercises in foggy weather. If you do morning exercises in foggy days, some toxic particles in the air will enter your respiratory system more easily. Haze is a systemic poison, and its harm can touch the nervous system, cardiovascular system, respiratory system, endocrine system and other systems, which will cause systemic damage. The problem of air pollution has become more and more serious, which has brought serious disasters to the world.

Haze brings harm to people. First, it leads to chest tightness and hypertension.

There are many pollutants in the air and the air pressure is low in foggy days. It is easy to induce acute attack of cardiovascular disease. Nowadays, when outdoors and exercising, sweat is not easy to be discharged, which leads to chest tightness and high blood pressure. Moreover, the air pressure in dense fog is relatively low, and people will feel irritable and their blood pressure will naturally rise.

Second, it has a great impact on the respiratory system.

Has become the knowledge of most people. The respiratory system has frequent contact with the external environment, and the contact area is relatively large. Hundreds of licoli can directly enter and adsorb on human body, respiratory tract and lung lobes. And most of it will be absorbed by the human body. Hazy weather will also weaken the surface ultraviolet rays, which will easily enhance the activity of bacteria in the air. Fine particles can bring bacteria and viruses deep into the respiratory system, causing infection.

Third, the damage of cardiovascular system.

It has long been confirmed by science. After summarizing a series of epidemiological studies in the field of cardiovascular diseases in 20 13 years, the European Journal of Internal Medicine found that long-term and short-term exposure to PM2.5 can cause a series of cardiovascular events, including myocardial infarction, stroke, heart failure, arrhythmia and venous embolism.

In short, smoke contains products of gasoline and diesel combustion, garbage gas and dust particles. Such as building, painting, domestic pollution, industrial pollution, etc. The gases and particles produced by many industries are complex. Once this particle enters the human body, it will seriously hurt us. Therefore, it is best not to do morning exercises in this weather.
