Why do some people think that foggy days are not suitable for morning running? Is running harmful when the weather is bad?

Some people have a healthy lifestyle and want to go out for exercise and running when they get up early, but it is not suitable for running in foggy days, otherwise it is very easy to inhale some pollutants into the body and cause damage to the body. Moreover, the visibility in foggy days is relatively low, and the ability to judge danger is not enough, which is very prone to traffic accidents. Running in bad weather can not only not exercise, but also threaten your health.

Foggy weather is very unsuitable for running, especially in the morning. When your activity increases and you breathe, it will gradually deepen and accelerate. But there are many harmful substances in foggy days, such as PM2.5, so experts also say that people with asthma and chronic bronchitis had better stop outdoor activities in foggy days and come out when the weather is good. Scientists believe that when it is foggy in the morning, if you go out for a run, the pollutants in the smog will directly affect human health. Some pathogenic microorganisms and harmful substances are dozens of times higher than ordinary atmospheric water droplets.

Moreover, when going out for exercise in the morning, the temperature is relatively low, the humidity is relatively high, and the temperature difference between indoor and outdoor is also large. The human body is suddenly stimulated by cold air, and it is very easy to catch a cold. Moreover, before the sun comes out, the oxygen content in the air is relatively low, and middle-aged and elderly people are prone to cardiovascular diseases when they go out for running, and patients with hypertension and diabetes are also prone to danger when they go out. And the air pollution in the morning is more serious, which is likely to lead to asthma.

When exercising in foggy days, people's breathing will gradually deepen with the increase of exercise. At this time, those pollutants in the air become invisible killers. Among them, harmful substances have a great influence on people's respiratory system, which makes people easy to breathe, and also causes chest tightness and palpitations, and some viruses will take advantage of it. So try not to go out in foggy days. Even if you go out, you must wear a mask and don't inhale harmful gases.
