Why are cardiovascular and cerebrovascular diseases prone to develop in winter? In low temperature, human blood vessels contract, causing vascular resistance and blood pressure to rise, increasing the chance of heart attack and cerebral infarction. In addition, due to the cold, people’s activities, sweating and drinking water are relatively reduced, which slows down the blood flow and increases the viscosity of blood, making it easy to form blood clots and increasing the chances of heart attack and cerebral infarction. So how to prevent the occurrence of cardiovascular disease in the winter for the elderly? Please keep in mind the following eight aspects: 1, avoid cold stimulation, add clothes in time when going out. 2, keep a relaxed mood, to avoid emotional excitement caused by the rise in blood pressure. 3, appropriate exercise, in general, in winter exercise if the weather is better, should choose more than three o’clock in the afternoon to outdoor activities, because this time is the highest temperature every day, and there is sun exposure, also good for the prevention of osteoporosis. It is best not to get up too early in the morning and go outdoors when it is still very dark because: (1)
The temperature is still low when it is dark, which can easily cause blood pressure to rise due to vasoconstriction. (2) There is not enough oxygen in the air, resulting in insufficient blood supply to the heart and brain vessels. (3)
Under normal circumstances, the body’s blood pressure rises from 6:00 a.m. to 10:00 a.m. is a peak, and hypertensive patients have lost the effectiveness of the antihypertensive drugs taken the day before, when blood pressure is more likely to rise. And the blood viscosity system is higher in the morning, which is the high incidence of cardiovascular diseases. For the above reasons, the occurrence of cardiovascular and cerebrovascular diseases is greatly increased. 4, do not overeat, to quit smoking and limit alcohol. 5, coronary heart disease patients with prostate enlargement should not strain with force when urinating. 6, eat more vegetables and fruits (without diabetes) and coarse fiber food, keep the bowels open, avoid constipation. 7, patients with angina attack coronary heart disease should minimize sexual life, before intercourse should contain nitroglycerin. 8, take your medication on time, especially antihypertensive drugs. Every morning after waking up first take antihypertensive drugs, and then do other things.
