A few years ago, I met an old man in his 50s. He was diligent and cheerful. The only regret was that his body was not very good. He had a history of chronic bronchitis (ie, “slow branchâ€) for nearly 20 years. Every fall and early winter, with the cold air invading, he had a cold for three days, coughing, coughing and wheezing. They were all commonplace, and sometimes they even experienced flustered, chest tightness. The old man took a lot of drugs, although the symptoms are reduced, but the root cause has not been eliminated, must wait until the following spring bloom, the elderly condition was "natural digestion."
Cold weather is indeed the main external cause of the "slow branch." Modern medicine has long explained the relationship between cold and the onset of bronchitis: cold air reduces the local temperature of the respiratory tract, shrinks the capillaries, and reduces blood in the local area. Coldness also leads to slowing of the cilia in the mucosal epithelium and the function of the bacteria that discharge the trachea into the respiratory tract. Weakened, viruses and bacteria from the outside world or parasites in the respiratory tract will take advantage of the disease and cause the onset of bronchitis. At the same time, under the stimulation of cold air, the secretion of bronchial mucous glands increased, smooth muscle spasm, resulting in increased airway resistance, drainage of discharge difficulties, causing acute exacerbations of the disease. However, the cold is, after all, only an external cause of "slow branch", not an internal cause. For the old “slow-branch†patients, proper physical exercise is beneficial to improve the body's ability to resist cold and resist, making the bronchial mucosa adaptable to cold air, which is actually a “cold-resistant exerciseâ€.
Let me talk about the old man I know. In the previous year, due to work and livelihood needs, he was hired as a buyer of a company. He ran the business all day long, or walked or cycled. It was cool and warm. I was amazed by the fact that this year's winter, the old man's "slow support" did not actually relapse. The doctor said that this is most likely the effect of cold resistance exercise. The old man is more confident. Since last year, he has always insisted on cold-resisting exercises. "Slow support" has never really relapsed.
Of course, an improvement in the condition of the elderly may be just an example. In general, elderly people do not have to imitate him "run everywhere." However, for patients with chronic bronchitis, active cold-resistance exercise is definitely beneficial to prevent the recurrence of “slow-branchâ€. There are many ways to exercise cold, outdoor walks, jogging, radio exercises, Tai Chi, indoor cold scrubs, etc., as long as it is cold sports, are considered cold exercise. No matter which method or method is used, the following principles must be followed: vary from person to person, step by step, measure by force, perseverance. It is best to start from the autumn, and the elderly can choose the items that are not too much exercise to avoid a sudden increase in heart and lung burden due to strenuous exercise.
