Spring is already in the air, which is soothing, but it is also an undeniable fact that the climate in spring is complex and changeable. Because it is difficult for blood vessels to expand and contract to keep up with temperature changes, middle-aged and elderly people are less adaptable to the changing climate in spring, so they must be highly alert to the occurrence of stroke and other cerebrovascular diseases at this time. Stroke is a cerebrovascular disease in which blood vessels in the brain are blocked or ruptured and blood cannot flow smoothly in the brain, causing brain dysfunction. A stroke with a blocked cerebral blood vessel is called a cerebral infarction, and a ruptured cerebral blood vessel is called an intracerebral hemorrhage. Cerebral hemorrhage is likely to occur in people with fragile blood vessels or in people with high blood pressure, while cerebral infarction is more common in people with high blood pressure and diabetes. Analysis of the seasonal incidence shows that the incidence is higher in spring in the male population over 60 years of age. To prevent stroke, it is important to insist that the treatment of common diseases in the elderly should not be slackened. For patients with high blood pressure, they should insist on taking antihypertensive drugs and keep their blood pressure within a reasonable range, generally not more than 140/90 for the elderly and not more than 130/80 for those with diabetes. For diabetic patients, insist on controlling blood sugar, fasting as much as possible not more than 7, after meals not more than 11. high blood lipid, obese friends should pay attention to a light diet, weight loss, if necessary, oral lipid-lowering drugs. Older people who have a taste for smoking and alcohol should quit smoking and drinking. The most important thing not to forget is an old friend: aspirin enteric tablets, which can prevent most of the cerebral infarction. According to the Yellow Emperor’s Classic of Internal Medicine, the key to preventing stroke is to maintain Yang energy in spring and summer, and to maintain Yin in autumn and winter. According to the Suwen Qi Tong Tian Lun, “Yang Qi is like the sky and the sun, if you lose it, you will lose your life and not manifest.” According to him, to maintain Yang in spring, we should pay attention to diet and living, emotional changes and other aspects. Early to bed and early to rise, adapt to early spring climate change, in the early spring when the weather is warm but still cold, temperature fluctuations, timely increase and decrease clothing, in the weather of temperature changes as little as possible; maintenance of Yang Qi, strengthen the body’s resistance; usually do not overeat, alcohol, should consume some hot food, should drink more water to prevent excessive water loss; eat more fruit, supplement a sufficient amount of vitamins. Labor and exercise should not be too fast and too hard, but should be measured and stopped; do not get angry and overexcited, maintain emotional stability to reduce the rise in blood pressure caused by cerebral hemorrhage; find the “signal” of stroke: such as diplopia (i.e., seeing objects with double vision), unilateral limb weakness or clumsiness, numbness, speech is not sharp, ambiguous, language Poor comprehension, as well as memory loss, vertigo or dizziness, unbalanced walking, facial paralysis, etc., should be promptly seen by a regular hospital cerebrovascular disease specialist to avoid delays. Those who usually have facial flushing, irritable heat in the heart and other yin deficiency and yang hyperactivity and imbalance of yin and yang should seek early medical treatment to prevent stroke.
