Should students go to physical education class in dusty weather? what do you think?

1, the impact on the respiratory system

In dusty weather, the inhalable particles in the atmosphere increase, and enter the respiratory tract after breathing, especially the particles with a diameter of 0.5 ~5 microns can enter the bronchi and bronchioles, and finally settle in the alveoli, thus causing strong stimulation to lung tissue, causing acute and chronic respiratory diseases such as bronchitis, pneumonia and emphysema. On the basis of the above lesions, the incidence of lung cancer will increase significantly.

2. The chances of spreading some infectious diseases have increased.

In the source and influence areas of dusty weather, inhalable particles in the atmosphere increase, air pollution intensifies, and many harmful pathogens, such as bacteria and viruses, are adsorbed on the surface of particles, which greatly increases the chances of the spread of some infectious diseases.

3. Effects on eyes, nose, throat and skin

The damage of sand and dust weather to eyes, nose, throat, skin and other direct contact parts is mainly manifested as irritating symptoms and allergic reactions such as runny nose, tears, cough and expectoration, which can lead to skin inflammation and conjunctivitis in severe cases.

4. It will aggravate the condition of patients with cardiovascular diseases.

Dust weather increases the chances of acute respiratory infection in patients with cardiovascular diseases, affects their cardiac function, increases the burden on the heart, and may lead to heart failure.
