Fog most affecting the respiratory tract
Sino-Japanese Friendship Hospital Respiratory doctor Yu Hongxia introduction, mist seemingly gentle, but inside they contain a variety of acids, bases, salts, amines, phenols, dust, pathogenic microorganisms and other harmful substances, and its content is several times the ordinary atmospheric water droplets on pose a huge threat to human health. Fog greatest impact on the respiratory system, can cause acute upper respiratory tract infection, acute bronchitis, bronchitis, pneumonia, asthma attacks and other diseases.
In addition, continuous fog lingers, it will increase the burden on the elderly circulatory system, may induce angina, myocardial infarction, heart failure.
Elderly: old chronic bronchitis multiple
Yu Hongxia told reporters, when the weather is cold, especially in dense fog appeared, tend to make old chronic bronchitis patients relapse, because the elderly bronchial epithelial atrophy, defense function decline, coupled with reduced immune function in the elderly, especially those suffering from elderly patients with chronic bronchial pneumonia, pulmonary heart disease, sensitive to changes in the external environment, there is fog in the morning to go out, easily onset.
Older patients with chronic bronchitis to develop good habits, certain physical exercise, increased disease resistance. In addition, we should strengthen nutrition, attention to climate change cold, change clothes, cold and warm (special attention to the back warm), try not to contact with flu patients, the use of diet to restore, vinegar fumigation, drugs taken orally or cold water bath and other prevention methods.
Children: Asthma recur
Children’s Hospital emergency department doctor told reporters, foggy day in addition to an increase in respiratory diseases, the probability that some children with asthma relapse is quite high.
Foreign pathology data reports have found that compared with the sunny, Children fog due to the onset of asthma symptoms and go to the emergency room increased 50 percent. When the temperature is below 17.7 ℃, the possibility of children due to asthma emergency department visits to four-fold increase.
From hospital admissions of children to see, children suffering from asthma in age from 7 months to 15 years of age, children hospitalized main symptoms are wheezing, shortness of breath and rapid breathing. Mist droplets contained affect bronchoconstriction in asthmatic children, changes in atmospheric pressure also make asthma symptoms worse.
Fog eat tofu and milk
Li Changping, Beijing Hospital of nutrition doctor told reporters, because of fog reducing sunlight, lack of children’s ultraviolet radiation, the body generates vitamin D deficiency, greatly reducing the absorption of calcium, can cause severe rickets in infants, children’s growth slows. In addition, due to the fog, low light and low pressure cause, some people will have the spirit of lazy in the fog, depression phenomenon. Winter foggy weather is very common, because of the resistance of the elderly and children is weak, this, Dr. Lee recommends should pay more attention in the diet, the elderly and children should keep the law of life sciences, avoid over exertion, drink plenty of water. To light diet, eat spicy food, eat more tofu, milk and other foods, if necessary, to supplement vitamin D.
■ Tips
Changes in breathing patterns to avoid smog
Experts advise that if you exercise in the foggy day, with the increase in physical activity, the person’s breathing is bound to deepen and accelerate, they will naturally be more harmful substances inhaled mist, so in foggy weather, especially with chronic respiratory diseases, should stop outdoor activities, but also the use of the following methods to prevent respiratory failure.
Abdominal breathing: the patient standing, sitting or lying position, try to relax, his hands placed under two costal arch, when requirements inhale the abdomen bulge. Reduced expiratory abdominal adduction. Can also be placed in the abdomen and hands a little pressure to increase intra-abdominal pressure, so diaphragmatic breath increased further reduce lung residual volume.
Shrink lip breathing: exhale tightening the lips, increasing expiratory airway resistance, preventing premature small airway occlusion, easy exhaled gas, can also reduce lung residual volume, improve ventilation.
