What harm does smog do to human body?

1 smog hurts the respiratory tract. The heavily polluted air has low cleanliness and contains a lot of dust, pollutants and microorganisms. Fog absorbs a lot of harmful acids, alkalis, salts, amines, phenols, pathogenic microorganisms and other substances, forming a very large smog. After inhaling these harmful elements, the human body is most likely to stimulate the respiratory system and easily induce or aggravate respiratory diseases such as tracheitis and pharyngitis.

2 smog is sad. A large number of particulate pollutants accumulate in foggy days, and the oxygen content in the air is too low, which is easy to lead to accelerated heartbeat, chest tightness and shortness of breath. In severe cases, it will not only cause myocardial infarction, but also cause palpitation, ischemia or injury. In particular, people who have already suffered from cardiovascular diseases should pay more attention to wearing masks when going out to avoid getting worse, and wash their faces and expose their skin in time after going out.

3 smog hurts blood vessels. When there is haze, there are many pollutants in the air, the air pressure is low, and the water vapor content is high when the fog is heavy. If people are outdoors at this time, sweat should not be discharged, which may easily lead to chest tightness and elevated blood pressure. Moreover, the foggy weather pressure is relatively high, which makes people feel extremely anxious; In foggy days, the temperature is generally low. If some patients with cardiovascular diseases suddenly come into contact with cold air, blood vessels will heat up and contract, which will also lead to high blood pressure, stroke, myocardial infarction and other phenomena, especially in the elderly.

4 Smoggy days affect emotions. In a cloudy environment all day, the pineal gland in the human body will secrete more pineal hormone, which makes the concentration of thyroxine and adrenaline relatively low. Thyroxine and epinephrine are hormones that stimulate cells to work. Once reduced, cells will become extremely inactive and people will appear listless.
