According to statistics, lung cancer is the most common cause of death among tumors. White collar workers may retort: We rarely smoke or do not smoke, so why must we get lung cancer? White collar workers have a point: most of them are clean and few of them are smokers. But lung cancer does not necessarily affect smokers, there are those who do not smoke and get lung cancer. Indoor air pollution and lung cancer in women White collar workers are vulnerable to lung cancer because of the following factors: l. White collar workers are in a state of long-term indoor and outdoor environmental pollution. As already mentioned, indoor electronic pollution and office equipment pollution can easily lead to lung allergies and bronchial asthma. And external dense air pollution is considered the main cause of lung cancer. Although everyone is exposed to external pollution, white-collar workers are exposed to indoor pollution for a longer period of time than the average person, so the lungs are prone to “weakness”; 2, very little exercise: exercise can make the lungs strong and healthy. Especially in the cold winter, running in the fresh air, lung gas and fresh air “convection exchange”, extremely beneficial to the respiratory tract and lungs. But white-collar workers have no fresh air and no time to exercise, so the lungs become increasingly atrophied and weak. The “enemy” attack, the defeated must be the weak. Those who have strong lungs rarely get lung cancer. 3. The white-collar diet is fine and high in fat, and the diet lacks selenium, a trace element to prevent lung cancer. This is also the cause of lung cancer. Chinese medicine regards human lungs as the “gold” of the “five elements”, and the two lung lobes are in the upper part of the human body. “The characteristic of “gold” is ‘cleanliness and sufficiency. Healthy lungs are like silk, smooth; diseased lungs are like rags, wrinkled. Dirty. To protect the lungs, we must protect some of its above-mentioned health characteristics. The living environment and lifestyle of our white-collar workers are not conducive to the healthy state of lungs. To prevent lung cancer, focus on the following aspects: 1, strive to indoor and outdoor air fresh; 2, adhere to the exercise of fresh air, so that the lungs are always “exhale new”; 3, selenium-rich, vitamin A-rich food.
