Is Running on Foggy Days Really Good?
In recent years, air pollution has become increasingly severe, with many cities experiencing persistent smog. This makes it difficult for many people to even go out, especially those who enjoy morning runs. However, foggy weather often doesn't deter their desire to exercise. So, is it good to run on foggy days? Let's take a look below.
Fog is water vapor condensation suspended in the near-ground low-altitude. In bustling urban and suburban areas, these condensation—small water droplets often contain various harmful chemicals from automobile exhaust and dust, pathogens, etc.
Especially in several days of heavy fog, due to weak cold air and no significant airflow, various pollutants accumulate near the ground. According to health department detection, fog droplets contain a significant number of FS (Foster) pathogens. It is a multicellular microorganism with autonomous motility and infectivity. It can cause disease individually or in combination with other bacteria.
Therefore, it is best not to exercise outdoors, especially along the roadside, and avoid vigorous activities between open spaces and buildings, to avoid inhaling excessive harmful substances and triggering bronchial inflammation, pharyngitis, conjunctivitis, sinusitis, various allergic diseases, and cerebral hemorrhage, etc.
Furthermore, it is not recommended to run or engage in other sports activities on foggy days because doing so increases oxygen consumption in the body, leading to accelerated breathing. At this time, due to the high humidity in the fog, it impairs the gas exchange of the alveoli, and the brain may experience dizziness and vertigo due to hypoxia. Simultaneously, during exercise, the increased activity of muscles and bones significantly increases heat production, requiring sweating to dissipate heat. However, on foggy days, the air is humid, making it difficult for sweat to evaporate, which makes people feel hot and uncomfortable.
Now we understand whether it's good to run on foggy days. The air on foggy days is full of dust, bacteria, and substances harmful to the human body, so it is recommended that if you want to exercise, you should do it at home. When you really need to go out, remember to wear a mask to protect yourself.
