What harm does fog do to human body?

The foggy weather has brought inconvenience to land, sea and air traffic, and this influence is obvious. Haze is not only harmful to human beings, but also causes hidden harm to human health, which should be paid great attention to.

Fog has strong adsorption, and the proportion of harmful substances such as acid, alkali, salt, amine, phenol and pathogenic microorganisms contained in fog is dozens of times that of ordinary atmospheric water droplets. When fogging, the air pressure is low, harmful substances are easy to gather in a certain area, and the particles forming the fog core are easy to be inhaled by people; At the same time, fog also causes the oxygen content in the air to decrease, and people will feel chest tightness when breathing. These harmful substances stimulate sensitive parts of human body and easily induce or aggravate some allergic diseases, such as tracheitis, pharyngolaryngitis and conjunctivitis. Some pathogens in fog can also cause headaches and even induce diseases such as hypertension and cerebral hemorrhage. Old and infirm people may be in danger of their lives.

In foggy days, the wind is weak, the air pollution is aggravated, and the air relative humidity is high. When the outdoor temperature rises obviously, and the smoke temperature at the smoke outlet of the indoor chimney is close to or lower than the outdoor ambient temperature, the diffusion of carbon monoxide produced during combustion is blocked or the escape is slow, and sometimes even the smoke pours indoors, resulting in carbon monoxide poisoning.

Close the doors and windows in foggy days to prevent outdoor fog from entering the room; Outdoor activities, especially some intense activities, should be minimized in foggy days. Wear a thin mask when you go out, and wash your face and bare skin immediately after you come back. The fog is coming, so the morning exercise should be suspended. Morning is usually when the fog is thick. At this time, sports will inhale a lot of harmful substances, causing diseases of throat, trachea and conjunctiva. Running in the fog for a long time is avoided, and the oxygen content in the fog is relatively small. However, when people run for a long time, the demand for oxygen increases sharply, and they are prone to dizziness, nausea, fatigue and other symptoms. Because the foggy weather is low, patients with hypertension and coronary heart disease should not take strenuous exercise to avoid inducing angina pectoris and heart failure.

Pay attention to a normal diet and eat less irritating food. If you feel unwell, you can take some cold granules or buccal tablets preventively. At the same time, we should be alert to damp-cold disease, and fog appears at low temperature in winter, which hinders the normal evaporation and heat dissipation of human body, has adverse effects on nephropathy, complications and chronic waist and leg diseases, and is easy to induce arthritis. So wear more shirts and pay attention to moisture and warmth.
