Why outdoor sports are not recommended in foggy days? What are the consequences of exercising in foggy days? The air quality index in big cities is generally weak in the morning, especially in rainy and foggy weather, where air pollution is serious and it is not suitable for exercise at this time. At night, the surface temperature of the city will drop. At this time, pollutants such as dust and many organic waste gases blown by vehicles and people cannot spread upwards, but fall back and float in the dense fog. In the morning, the concentration of polluted air near the ground in big cities is the highest. When people are training, inhaling will aggravate the acceleration, thus inhaling too much polluted smoke through the respiratory system, which is harmful to human health.

In rainy and foggy weather, the environmental pollution near geological structures is serious, and fine particles are constantly fused with pollutants in the process of change, so the air index is damaged. Moreover, some harmful substances mixed with water vapor will become more toxic and have greater side effects. In addition, the particles that make up the fog core are easily inhaled by people and stay in the body. The amount of air inhaled during strenuous exercise is much more than usual, which aggravates the harm of harmful substances to the body and is very easy to cause or aggravate various diseases. In short, strengthening exercise in rainy and foggy weather will do more harm to the body than the benefits of exercise, and exercise in rainy and foggy weather will lose more because of small.

In rainy and foggy weather, the air humidity is high. When people jog, climb mountains or do other sports, the amount of exercise of muscles and human bones increases, resulting in a significant increase in the amount of heat generated in the body, which requires a lot of sweating to discharge heat. In fog, fitness exercise is often blocked by the high pressure and humidity of water vapor, and sweat does not volatilize, which makes people feel uncomfortable.

When there is fog, the sky is gradually blurred and visibility is poor. When people do other sports such as jogging and cycling in foggy days, they are very prone to accidents because of the large number of vehicles on the road and poor visibility. Especially for the elderly, their eyesight and English listening are poor and their reaction is slow, so they are not suitable for going out to exercise in rainy and foggy weather.
