The meteorological department predicts that the minimum temperature will fall to single digits today and tomorrow, accompanied by rain and snow. Liu Xuezheng, director of the geriatrics department of the First Affiliated Hospital of traditional Chinese medicine, gives advice to the citizens on how to deal with the "cold spring". The temperature fluctuates from high to low, which is a test for cardiovascular and cerebrovascular diseases. Such temperature is easy to lead to unstable blood pressure and increase the incidence of cardiovascular and cerebrovascular diseases. The heat balance ability of the elderly and children is poor, and the circulatory system is easy to be stimulated by "late spring cold". The elderly should beware of sudden cardiovascular and cerebrovascular diseases, and children should pay attention to the prevention of respiratory tract infection. Special people should pay attention to the prevention of hypertension, arteriosclerosis, stroke, angina pectoris and myocardial infarction. In early spring, some young people who love beauty will wear thin clothes early. At this time, we must pay attention to the warmth of knees and ankles. Do not wear too thin or even expose ankles too early for the sake of beauty and fashion, so as to avoid rheumatoid arthritis. At the same time, citizens should adhere to the "spring cover", but do not cover too much to avoid sweating. Ensure timely indoor dust removal and ventilation to reduce and inhibit bacteria. When the weather is too cold, reduce outdoor activities. If you must go out, wear a mask, protect your mouth and nose, avoid colds, tracheitis, pneumonia and rhinitis, and pay attention to the warmth of your head, neck, joints and feet. In terms of diet, it is dry in spring. It is recommended to eat more foods that strengthen the spleen and stomach, such as chicken, duck, lean meat, eggs, vegetables and fruits that are rich in vitamins and trace elements and easy to digest, which will help to increase the body's immunity.
