Why should we avoid exercise in foggy days?

Do you know that?/You know what? Do you know that?/You know what? The fog in the city is different from the fog in the countryside. Its biggest feature is that it contains a lot of substances harmful to human body. With the development of urban industry and transportation, dust particles and harmful gases discharged into the atmosphere have greatly increased. Dust, dust, carbon monoxide and sulfur dioxide in the air are seriously polluted. They become particle condensation nuclei, absorbing water vapor floating in the air to form fog.

Exercise in dirty fog will inevitably inhale these toxic substances, causing pharyngitis, tracheitis, conjunctivitis and allergic diseases. In addition, exercise in the morning fog will hinder the exchange of oxygen and carbon dioxide in alveoli due to a large amount of water vapor in the fog, which will make the body organs and tissues lack oxygen supply. Therefore, when you exercise in the fog, you often feel poor breathing, chest tightness and discomfort, and you are easy to get tired.

You should choose a good climate to take part in physical exercise. In foggy season, outdoor sports can be arranged in the afternoon. On weekdays, the pollution in the city is heavier before sunrise or in the evening, so the exercise time can be arranged between 6 am and 3 pm. The air is freshest after rain, so it is best to take physical exercise at this time.

When exercising, you can choose places with less traffic, more flowers and trees and fresh air, such as lawns, playgrounds, parks or secluded roads, forests and vaginas.

Around us, many people are used to getting up, walking and exercising in the morning to breathe fresh air. But if you exercise or walk in the fog, it's bad for your health.

Fog is mainly composed of tiny water droplets, in which some toxic chemicals such as acid, alkali, salt, oxide, benzene, phenol and amine are dissolved. In particular, there are many pollutants from smokestacks of industrial and mining enterprises and automobile exhaust, and acid fog and photochemical smog may also form in some areas. Moreover, this fog is not easy to disperse, and bacteria and viruses can easily survive in it. Therefore, when people run, walk or do other physical exercises in the fog, they will naturally be affected by pollutants in the fog, which will stimulate or damage the human respiratory organs and even cause diseases such as emphysema and lung cancer. Therefore, it is not advisable to exercise in foggy days.
