Reasons why running in foggy weather is bad

When the water vapor is sufficient, the breeze and the atmosphere are stable, the temperature is close to 0 o'clock and the relative humidity reaches 100%, the water vapor in the air will condense into fine water droplets suspended in the air, reducing the visibility on the ground. This weather phenomenon It’s called fog. Fog occurs in spring between February and April. When the water vapor suspended in the atmosphere condenses in the air and the visibility is less than 1 km, meteorology calls this weather phenomenon fog. The formation of fog: one is cooling, and the other is humidification to increase the water vapor content. Types of fog include radio fog, advection fog, mixed fog, evaporative fog, and smog. The reason why running in foggy weather is bad is due to the water vapor condensation suspended in the low air. In busy urban suburbs, these condensation - small water droplets often contain a variety of harmful chemicals in vehicle exhaust, floating dust, pathogenic microorganisms, etc. Especially when there is heavy fog for several consecutive days, due to strong cold air and no obvious air flow, various pollutants accumulate near the ground. According to testing by the health department, there are a considerable number of f"s (Fu's) pathogens in the fog. It is a multi-cellular microorganism with the ability to move and infect autonomously. It can cause disease independently or together with others. Therefore, In foggy weather, it is best not to practice outdoors, especially on the side of the road, and do not perform strenuous exercise between open spaces and buildings to avoid absorbing too many harmful substances and inducing bronchitis, pharyngitis, conjunctivitis, rhinitis, Cerebral hemorrhage, etc. In addition, avoid running and other physical exercises in foggy days, because when doing these activities, the oxygen consumption in the body will increase, and breathing will inevitably deepen. At this time, the fog contains more water vapor, which hinders the gas exchange in the alveoli. , causing dizziness, dizziness and other discomforts due to lack of oxygen in the brain; at the same time, during exercise, due to the increased activity of muscles and bones, the body's heat production increases significantly, requiring sweating and heat generation. However, foggy weather is humid and sweat is not easy to evaporate. It is not conducive to skin heat dissipation and makes people feel stuffy and uncomfortable. In addition, there is a lot of carbon dioxide between the sun and the sun when the wind is weak and the carbon dioxide is difficult to dissipate in the morning, just like on the park avenue. The same exercise is not suitable.
