The quality of the air that enters the lungs affects the body's susceptibility to infections, including coronavirus, doctors say. To prevent the disease, experts recommend ventilating the room and cleaning the premises from dust. Let's figure out which good habits will help strengthen the lungs and reduce the risk of adverse effects against the background of COVID-19. No dust and dirt Allergist-immunologist Vladimir Bolibok said that what a person breathes affects the susceptibility of his body to various infections. Dirty air, according to the specialist, increases the risk of infection. "The more oxygen in the air, the easier a person will tolerate respiratory disease, including coronavirus infection. Cleanliness of the air affects susceptibility, the dirtier it is, the more susceptible our airways are to any viral infection, including coronavirus," explained the specialist. According to the doctor, it is possible to reduce the risk of infection if you always breathe clean air, that is, sleep should not be an exception. The specialist added that in other rooms, people are usually awake, so they can control the air quality. Including, if necessary, ventilate the room or leave it. Earlier, scientists from the United States talked about the differences between coronavirus pneumonia and the one that was caused by other diseases. Experts from Northwestern Medicine noted that viruses or bacteria can usually spread over large areas of the lungs in a few hours. At the same time, modern drugs are able to quickly cope with them. The way SARS-CoV-2 works is more similar to the effect of several forest fires, scientists believe. The virus settles in many small areas of the lungs, after which it hijacks the lungs' own immune cells and uses them to spread over a long period. As the infection spreads, it leaves behind damage, fever, and other unpleasant consequences. Guarding the lungs Pulmonologist, Honored Scientist of the Russian Federation Yevgeny Shmelev, in an interview with Moscow 24, said that the lungs are an immunologically active organ that must be treated with care. According to the specialist, you can take care of them by quitting smoking. "Smoking is an absolutely harmful occupation. Not only active, but also passive smoking is harmful. In this case, not only respiratory diseases arise, metabolism is disrupted," said Shmelev. According to the pulmonologist, brisk walking contributes to the strengthening of the lungs. At the same time, breathing exercises will help in taking care of the lungs, the doctor is sure. According to him, it is best to choose the right set of exercises for a specific person with a specialist. "There are many different options according to the authors, but the whole point of gymnastics lies in a reasonable tension, a load on the muscles of the respiratory muscles. Here you must not overdose, you must listen to your body, practice incrementally," explained Shmelev. In turn, therapist, immunologist Irina Yartseva and therapist Lyudmila Lapa agree that it is necessary to take care not only of the lungs separately, but also of the immune system as a whole. "A healthy diet, rest, a healthy lifestyle, regular physical activity will restore the functioning of any immune system, not only the lungs," said Lyudmila Lapa. According to Yartseva, it is important to eat vegetables and fruits, take vitamin D in preventive doses in winter, and get enough sleep. In addition, according to Yartseva, it is necessary to humidify the air at home."Now the cold, frost, heating is so pronounced in the premises. It affects the mucous membrane of the nose, upper respiratory tract, of course, it is easier to get sick with ARVI," the doctor explained. At the same time, to maintain the normal state of the nasal mucosa, it should be moistened with various solutions, the immunologist summed up.
