Eat more tofu in winter
The fog most affects the respiratory tract
Yu Hongxia, a respiratory doctor at the China-Japan Friendship Hospital, said that the mist looks mild, but it contains various harmful substances such as acids, alkalis, salts, amines, phenols, dust, and pathogenic microorganisms. Its content is several dozen times that of normal atmospheric water droplets. Human health poses a great threat. Fog has the greatest impact on the respiratory system and can cause acute upper respiratory tract infections, acute bronchitis, bronchitis, pneumonia, and asthma attacks.
In addition, the fog will continue to increase, will increase the burden on the elderly circulatory system, may induce angina, myocardial infarction, heart failure and so on.
The elderly: multiple chronic bronchitis
Yu Hongxia told reporters that when the weather turns cold, especially the occurrence of dense fog, old patients with chronic bronchitis tend to relapse because the bronchial epithelium shrinks, the defense function declines, and the immune function of the elderly decreases, especially those suffering from The elderly people with chronic bronchopneumonia and pulmonary heart disease are very sensitive to changes in the external environment. They are vulnerable to morbidity in the early morning when there is thick fog.
The elderly patients with chronic bronchitis should develop good living habits, perform certain physical exercises, and improve disease resistance. In addition, nutrition should be strengthened, pay attention to changes in climate hot and cold, in time to increase or decrease clothes, cold and warm (especially pay attention to back warmth), try not to contact with cold patients, using dietary care, vinegar fumigation, internal medicine or cold water bath and other preventive methods.
Children: Asthma relapses easily
Children's Hospital emergency doctors told reporters that in addition to the increase in patients with respiratory diseases in the foggy days, the probability of recurrence of asthma in some children is quite high.
Reports of pathological data have been reported abroad and it has been found that compared with sunny days, the number of children who go to the emergency room due to the onset of asthma symptoms increases by 50%. At temperatures below 17.7°C, children are four times more likely to attend an emergency department for an asthma attack.
From the perspective of admissions to children's hospitals, children with asthma are from 7 months to 15 years old. The main symptoms of hospitalization in children are wheezing, shortness of breath and shortness of breath. The water droplets contained in the mist affect the bronchoconstriction of asthmatic children, and changes in atmospheric pressure can also worsen asthma symptoms.
Eat more tofu and milk in foggy days
Li Changping, a doctor at the hospital's nutrition department, told reporters that due to the reduced sun exposure in the fog, children's lack of UV radiation, the body's lack of vitamin D production, greatly reduced the absorption of calcium, severe infant rickets can cause, children grow slow. In addition, due to the weak light in the fog and the resulting low pressure, some people in the fog will produce mental lazy, depressed mood. The foggy weather in winter is very common. Due to the weak resistance of the elderly and children, Dr. Li suggested that more attention should be paid to the diet. The elderly and children must maintain scientific rules of life and avoid overwork and drinking. Should pay attention to light diet, eat less irritating foods, eat more tofu, milk and other foods, if necessary, to add vitamin D.
â– Tips
Change breathing method to avoid poison fog
Experts remind that if you exercise on a foggy day, as the amount of exercise increases, people's breathing tends to deepen and accelerate. Naturally, they will inhale more harmful substances in the mist. Therefore, in the foggy weather, especially in the fog, People with chronic respiratory diseases should stop outdoor activities. The following methods can also be used to prevent respiratory failure.
Abdominal breathing method: the patient takes a seat, sitting position or lying position, try to relax, two hands placed under the two ribs, ask for inspiration when the abdomen bulge. When you exhale, your abdomen shrinks. You can also put your hands on the abdomen and pressurize slightly to increase the intra-abdominal pressure. When you exhale, you can increase the diaphragm and reduce the amount of residual air in your lungs.
Lip Respiratory Method: Lip tightening during exhalation, increasing airway resistance during exhalation, preventing premature obstruction of small airways, making gas easier to exhale, can also reduce residual air volume in the lungs and improve ventilation.
