1 How does airborne infection occur? 2 Tell us about lung diseases. How can these diseases be prevented? 3 Why is vital capacity of the lungs an important indicator of health? 4 List the basic rules of respiratory hygiene.

1. This type of infection begins with a person whose respiratory tract is infected. When sneezing and coughing, they spread into the environment. As soon as a person inhales the air in which such infectious microorganisms live, he becomes infected.
2. Lung diseases include lung cancer, tuberculosis, asthma, whooping cough. To prevent these diseases, it is recommended to lead a healthy lifestyle, eat right, keep the apartment clean and avoid mold, and get the appropriate vaccinations on time.
3. Lung capacity affects a person’s stamina. Quality breathing saturates the blood with oxygen, which makes a person more alert and active.
4. Human lungs are like a sponge, absorbing all the “garbage” from the environment. These include exhaust fumes, cigarette smoke, various pathogens, and mold spores. All of these substances are equally hazardous to health. To prevent lung disease, it is recommended to keep your apartment dry and clean (to prevent inhalation of dust mites and mold). Also, during the cold season, it is best to wear a medical mask. And finally, to reduce the chances of lung cancer, you need to avoid smoking and smoky places.
