Recently, strong cold air has frequently affected Shandong, bringing widespread rain and snow, strong winds and persistent low temperatures. In this case, in addition to respiratory diseases, cardiovascular and cerebrovascular diseases are also common diseases. How to do a good job of health protection in extremely cold weather?The reporter interviewed Wang Liansen, director of the Institute of Health Education and Promotion of the Shandong Provincial Center for Disease Control and Prevention.
Keeping warm is important. Wang Liansen said: "When the weather becomes cold, vasoconstriction will increase blood pressure, thereby increasing the burden on the heart and cerebrovascular blood vessels of some hypertensive patients, and can induce cerebrovascular diseases such as cerebral hemorrhage and cerebral infarction. For people suffering from cardiovascular and cerebrovascular diseases, keeping the head, hands and feet warm can reduce the cardiovascular and cerebrovascular burden caused by excessive vasoconstriction. ”
Reduce non-essential outings and exercise at home. Slippery ground after snow may cause some elderly people to fall under mobility conditions, resulting in fractures or traumatic diseases. Wang Liansen said that osteoporosis is one of the common diseases of the elderly, and going out blindly will increase the risk of falls.
In extremely cold weather, the flu is also more rampant. For patients with chronic diseases, especially the elderly, essential medicines can be kept at home for about 2 weeks. Wang Liansen said: "You can always have some cooling and cough medicines at home, first lower the body temperature, and then if the body temperature continues to be above 38 and cannot be relieved, you need to seek medical attention as soon as possible." Wang Liansen mentioned that timely flu vaccination is also one of the ways to effectively cope with the flu season.
On December 13, the National Bureau of Disease Control and Prevention issued the "Guidelines for Public Health Protection during the Cold Wave", and there are three main categories of people who need key protection, including sensitive groups, such as infants, children, pregnant women, and the elderlyPeople with chronic underlying diseases, such as cardiovascular and cerebrovascular diseases, respiratory diseases, etc.;Outdoor workers, such as traffic police, sanitation workers, construction workers, couriers, food delivery workers, etc.
According to the guidelines, the possible health risks of the cold wave include the formation of chilblains due to superficial** damage, which can worsen the pain of patients with arthritis and rheumatoid arthritisIt is easy to induce airway spasm and abnormal immune function of the respiratory systemIt is easy to cause cardiovascular and cerebrovascular diseases;It may also exacerbate diseases of the urinary system and endocrine system.
If you have chills, measure your body temperature in time, and seek medical attention immediately if you have symptoms such as body temperature lower than 35, collapse, memory loss, and slurred speech. If you cannot seek medical attention, it is advisable to go to a warm place or take shelter from wind and rain to reduce heat loss. If the clothing is wet, change into dry clothes in time to warm the core area of the body and replenish hot drinks (avoid alcohol and coffee drinks).
