Many people are keen on exercising, but what you must know is, why not exercise in foggy days?

The air quality in cities in the morning is generally poor, especially in foggy days, and the air pollution is serious, so it is not appropriate to exercise at this time. At night, the ground temperature of the city will drop. At this time, pollutants such as dust and a lot of waste gas raised by cars and people can't spread upward, but fall back and suspend in the fog. By early morning, the pollution concentration of the air near the ground in the city is the highest. When people exercise, their breathing will deepen and accelerate, thus attracting too much polluted smoke through the respiratory tract, which will do harm to human health.

In foggy days, the air pollution near the surface layer is serious, and the fog drops are constantly combined with pollutants during the drifting process, so the air quality is seriously damaged. Moreover, some harmful substances will become more toxic when combined with water vapor. 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 physical exercise is much more than usual, which aggravates the damage of harmful substances to human body and easily induces or aggravates various diseases. In a word, exercising in foggy days does more harm to the body than the benefits of exercising, and exercising in foggy days is not worth the candle.

the air humidity is high in foggy days. When people run, climb mountains or do other sports, the activity of muscles and bones is enhanced, which leads to a significant increase in heat production in the body and requires a lot of perspiration and heat dissipation. Exercise in fog will lead to poor skin heat dissipation due to high water vapor pressure and humidity, and sweat will not evaporate easily, making people feel uncomfortable all over.

when there is fog, the sky is hazy and the visibility is poor. When people run, ride bicycles and do other sports in fog, they are prone to accidents because of the large number of vehicles on the road and poor visibility. In particular, the elderly have poor eyesight and hearing, slow reaction, and are not suitable for going out to exercise in foggy days.
