Some people who have a cold will have bronchitis, and patients with bronchitis often have coughs or persistent coughs. However, patients do not have to panic because bronchitis often heals itself after a short-term attack, and some self-treatment methods are also effective.

　　How does bronchitis occur?

　　The human respiratory organ is like an overhanging tree, the trachea is the trunk, the bronchus is the branch and the branch, the air is drawn into the trachea by the person, passes the bronchus, puts Oxygen is delivered to the lungs. There is a layer of mucous membrane on the inner wall of the bronchus. Their normal function is to produce mucus, which keeps the bronchus lubricated and acts as a scavenger. When viruses and bacteria invade, the mucous membrane is a clear enemy of the offender, and a large amount of mucus is produced, which blocks the bronchial tubes and affects the normal breathing of people. So, in order to make the bronchial tubes unobstructed, and make people get enough oxygen, they coughed. Generally speaking, cold viruses pass through organs such as the nasal cavity and throat, and then go deeper into the trachea and bronchi. Sometimes, bacteria can also cause viral infections and induce bronchitis. People with allergic reactions, suffering from asthma, smoking and living in a heavily polluted environment are more prone to infectious attacks because their respiratory tracts are often stimulated, suitable for the propagation and survival of viruses and bacteria.

How much self-therapy is there

　　Because the cough is caused by bronchitis; the mucus is produced to reduce the feeling of chest obstruction, so you can use mucus to dilute the mucus so that Yu coughed out of the body. Unless you cough overnight and do not sleep at night, generally do not use antitussives to suppress your cough, which will affect the patient''s own disease resistance. Hot and humid hot air can dilute mucus and reduce asthma caused by coughing. Taking a hot shower or preparing a basin of hot water, covering your head with a towel, and inhaling the heat from the basin is a simple and effective method. Another way to make mucus easier to cough up is to make the bronchi horizontal above the mouth and trachea. The method is: lying on the bed face down, put a pillow on the abdomen; or put a pillow on the waist and hips face up. Each of these two methods should be used for one to twenty minutes. To make this method more effective, it is best to drink two glasses of plain water two hours ago. Bronchitis is often accompanied by fever and body pain, you can take aspirin and rest. If chest pain is caused by continuous coughing, hot water bottle can be used to relieve the pain.

　　Avoid chronic treatment in a timely manner

　　Some people can heal themselves after a few days of bronchitis, but some people may have asthma before the bronchus returns to normal width. If there is no improvement for a week or two, a doctor should be consulted to avoid chronic changes. Symptoms such as breathlessness, cold discomfort, sweating, and blood in the sputum during rest should consider pneumonia and seek immediate medical attention. Once it turns into chronic bronchitis, it is quite troublesome. This bronchitis is neither a virus nor a bacterium. Most of it is caused by smoking and constant stimulation. It is characterized by recurrence every year, which can last for more than two years. There may be a constant cough that lasts more than three months at the time of the attack. Patients with chronic bronchitis are particularly sensitive and prone to colds, flu and pneumonia.
