Why not exercise in fog
Fog is a small water droplet floating in the low air on the earth's surface. It dissolves various harmful substances such as acid, salt, amine, benzene, phenol, and adheres to some harmful solid particles such as dust and pathogenic microorganisms.
Exercise in the fog, such as long-distance running, will make some sensitive parts of the body contact with these windowed substances, which may cause tracheitis, laryngitis, conjunctivitis and allergic diseases. If you inhale 285 mm dense fog, the gas exchange in the alveoli will be affected, and then cause the lack of oxygen supply. Running in the fog will also feel suffocating in the chest, oppressive and prone to fatigue. Therefore, do not do strenuous exercise in the fog morning.

Fog has four major hazards to human body
1. Cause upper respiratory tract infection
The number of outpatients with upper respiratory tract infection increased significantly, with cough, sneeze and runny nose as the main symptoms. This is directly related to the low pressure of fog weather, poor air circulation and the increase of inhalable dust. These pollutants will stimulate the respiratory tract and cause bronchoconstriction, so the incidence of cough, asthma, allergic rhinitis and so on will increase.
Experts remind: in this weather conditions, healthy people will also have throat discomfort and other phenomena. Therefore, we should try our best to reduce outdoor activities, open windows and ventilate frequently at home and office places, and often go to places with fresh air to change the environment, so as to combine work with rest, live a regular life, reduce unnecessary social intercourse, avoid bad stimulation of tobacco and alcohol, and at the same time, we should drink more water, accelerate metabolism and discharge waste.
In addition, do not take antibiotics as soon as upper respiratory tract infection occurs, because more than 90% of upper respiratory tract infections do not need to take antibiotics, as long as symptomatic and antiviral treatment can be achieved. Blind use of antibiotics will lead to allergic reactions, toxic and side effects, aggravating the condition.
2. Induce asthma and chronic bronchitis
Inhalable particles, sulfur dioxide and other pollutants in foggy days are the main factors inducing asthma and chronic bronchitis. These pollutants stimulate the bronchi of asthmatic patients and cause respiratory response. Asthma patients will have wheezing, chronic bronchitis patients will have upper respiratory tract infection with fever, spitting yellow sputum, etc., which will induce and aggravate the original disease.
Experts remind: asthma patients should try to avoid the stimulation of allergens. In foggy days, there are a lot of suspended substances in the air. Patients should go out as little as possible to reduce the contact with allergens. When going out, they should wear masks, which is the most simple and effective way to reduce respiratory tract irritation. Exercise should avoid the time of dense fog, such as morning and evening, and choose fresh air places such as parks and suburbs.
The patients with asthma and chronic bronchitis can also take medicine in advance under the guidance of professional doctors, and reasonable treatment will help to prevent and reduce the occurrence of original diseases. In terms of diet, it is advisable to choose light and easy to digest foods rich in vitamins. Drink more water and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also moisten the lungs and remove dryness, eliminate phlegm and cough, strengthen the spleen and kidney, and nourish the lungs.
