Is foggy weather suitable for outdoor sports?

Of course not. Haze weather is caused by a large number of extremely fine dust particles, smoke particles and salt particles floating in the air evenly, so haze weather is actually a kind of air pollution.

Smog weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out in foggy days, and it is not suitable for morning exercise, otherwise it may induce diseases and even heart attacks, which may be life-threatening.

Experts pointed out that foggy days are the "dangerous period" for patients with cardiovascular diseases because foggy days are depressed and the oxygen content in the air drops, which makes people feel chest tightness easily. Wet and cold fog in the morning can also cause cold stimulation, which can easily lead to blood pressure fluctuation, vasospasm and increased heart load. At the same time, some pathogens in fog can cause headaches and even induce diseases such as hypertension and cerebral hemorrhage. Therefore, people with cardiovascular diseases, especially the elderly and infirm, should not go out in foggy days, let alone do morning exercises in foggy days to avoid danger.

Even healthy people are not suitable for outdoor sports in foggy days.
