As the saying goes, "cold before frost, cold after snow". After a heavy snowfall, the temperature dropped significantly. At this time, the public should pay more attention to preventing falls, and beware of the occurrence of "snow diseases" such as cardiovascular and cerebrovascular diseases and respiratory diseases.
【High incidence of cardiovascular and cerebrovascular diseases, do not go out to exercise prematurely】
A sudden drop in temperature after snow can cause the body's blood vessels to constrict. If there is a history of cardiovascular disease, the sudden contraction of blood vessels will lead to obstruction of blood flow, interruption of blood flow supply, and the incidence of myocardial infarction and heart failure will be greatly increased. Doctors remind that patients with chronic underlying diseases such as hypertension, diabetes, and coronary heart disease should monitor blood pressure and blood sugar at any time, pay attention to keeping warm, adding clothes at the right time, and exercising in the morning should not be premature.
Wang Kun, deputy chief physician of the Department of Cardiology of Nanjing Drum Tower Hospital, said: "Exercising too early outdoors may cause blood vessel contraction, and the problem caused by blood vessel contraction is that blood pressure will rise. When blood pressure rises, the incidence of heart disease increases, such as coronary heart disease. At the same time, the increase in blood pressure can cause an increase in the incidence of cerebrovascular diseases, such as cerebral infarction and cerebral hemorrhage. Therefore, we do not recommend going out for morning exercise at five or six o'clock or six or seven o'clock before the sun comes out. You can wait until after ten o'clock, when the temperature has begun to rise, and then do outdoor exercise. ”
【Indoor ventilation to reduce the incidence of respiratory diseases】
After the snow, some citizens reduced the number of outings. However, the temperature changes sharply, the resistance of the weak to the disease will decline, and many people will close the windows and use air conditioners and electric heaters when they are at home. If the windows are not opened frequently for ventilation, it is easy to cause bacteria to breed in the home, increase the risk of virus transmission and the incidence of the common cold.
Wang Kun said: "It is very necessary to open the window for ventilation at least twice a day. Each time the window is opened for ventilation, we recommend 10 to 15 minutes. Maintaining indoor temperature and humidity can reduce the incidence of respiratory diseases. ”
