Can the fog in the mountains breathe? My hometown is full of fog.

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.

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, but people's demand for oxygen increases sharply after running for a long time, 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.
