How about outdoor sports in foggy days?

Fog is composed of countless tiny water droplets, which contain a lot of harmful substances such as dust and pathogenic microorganisms. If you exercise in foggy days, due to the increase of breathing volume, you will inevitably inhale more toxic substances, which will affect the supply of oxygen, thus causing chest tightness, dyspnea and other symptoms, and in severe cases, rhinitis, pneumonia, tracheitis, conjunctivitis and other diseases will occur. Humidity is high in foggy days, which affects the posture of the skin and is not conducive to exercise.

If there is fog in the morning, these fogs will often suck air impurities and even bacterial pathogenic microorganisms into people's upper respiratory tract. When the human body's resistance drops, respiratory tract infection will flow to the lower respiratory tract, that is, bronchopneumonia, including lung cavity infection and even chest infection, which will further aggravate the condition, so it is best not to go out for a walk in foggy days to avoid such weather. In addition, for patients who have undergone surgery or lung cancer surgery in the past, we should pay attention, because his department has caused some trauma, and if we do not pay attention to the stimulation of cold air and air pollution, it will aggravate the condition.

At the same time, experts also reminded that when the temperature drops too fast, people with poor cold tolerance and cold tolerance had better not do morning exercises, because after the temperature drops, some pathogenic microorganisms that cause upper respiratory tract infections become active, and the immunity of the elderly and children decreases, which will also cause upper respiratory tract infections. The stimulation of cold air can also induce angina pectoris. Professor Ma suggested that citizens who like to get up early and do morning exercises can adjust their winter morning exercise time appropriately, choose a relatively fresh air environment or do indoor exercise, and it may be better to change morning exercise to evening exercise.

Now some scholars believe that getting up in the morning is not as good as doing exercise in the afternoon or evening. I think it makes sense. Taking exercise and taking a proper walk in the afternoon means walking, jogging and relaxing according to your own ability, which is definitely good for the human body.
