The continuous high temperature and high humidity has made many people feel dizzy. During this period, the number of stroke patients in the hospital also increased. Feng Lisha, director of the Second Department of Encephalopathy, Affiliated Hospital of the Municipal Academy of Traditional Chinese Medicine, suggested that in the consciousness of many people, strokes mostly occur in winter and spring. In fact, there are two peak periods of stroke in a year, one is the cold winter and the other is the hot and humid summer. In the dog days of continuous high temperature and high humidity, one should also be alert to stroke.
The high temperature and high humidity in midsummer are very detrimental to the cardiovascular and cerebrovascular. When exposed to a high temperature environment, the human body sweats a lot to increase heat diffusion. If water is not replenished in time, it may lead to increased blood viscosity, decreased cerebral blood flow, and induced ischemic stroke. At the same time, when the temperature is extremely hot, the blood vessels of the human body expand, the blood circulation is accelerated, and the blood pressure is easily fluctuated. In high humidity weather, low air pressure, high humidity, and low oxygen content in the air may induce ischemic stroke. In addition, many places and households use air conditioners in summer, forming a large temperature difference with the hot outdoor. When entering a low-temperature air-conditioned room from the outside, the blood vessels on the body surface will rapidly contract in a large area, and the blood pressure fluctuates violently, which increases the risk of stroke. morbidity risk.
In hot and humid weather, if you suddenly experience dizziness, vomiting, transient amaurosis, double vision, skewed eyes, slurred speech, numbness and weakness on one side of the limb, unsteady walking, etc. In this case, you must be vigilant, go to the hospital in time, and beware of sudden stroke.
Although midsummer is the season of high incidence of stroke, more prevention in daily life can reduce the incidence of stroke. When the weather is too hot, the elderly should reduce going out, especially during the hottest hours. When using an air conditioner at home, you can choose the dehumidification mode, which is cool and reduces humidity; the temperature should not be adjusted too low, and the difference between the outdoor temperature and the outdoor temperature should not exceed 7°C to 8°C. Ensure adequate drinking water every day, adults should drink no less than 2000 ml of water per day. Patients with diabetes and hyperlipidemia should add more water on this basis to reduce blood viscosity and prevent thrombosis. After sweating a lot, you should also rehydrate in moderation, or drink some electrolyte-containing drinks. The daily diet should be light, increase the proportion of vegetables, protein, fruits, beans, whole grains, eat less high-fat and high-sugar foods, eat regularly, not overeating, and pay attention to dietary hygiene to avoid diarrhea and lead to electrolyte imbalance in the body , induce cardiovascular and cerebrovascular diseases.
Many elderly people have the habit of morning exercise. Although the sun rises early in summer, if you exercise in the morning, the human body will be in a state of sympathetic nervous excitement, blood pressure will rise, heart rate will increase, blood viscosity will increase, and the risk of stroke will increase. You can put exercise time after dinner. Hypertensive patients should pay attention to changes in blood pressure, and when blood pressure is found to be low, they should adjust their medication according to the doctor’s advice in time to reduce the risk of cerebrovascular disease. If you have atrial fibrillation, seek medical attention promptly to check for stroke risk.
It is convenient for the elderly to wake up at night or when they get up in the morning, they should not move too fast. They can follow the “three and a half minutes” principle, that is: after waking up, lie down on the bed for half a minute, and then sit down. Get up for half a minute, then drop your legs to the edge of the bed for another half a minute, then stand up and move around. After these three and a half minutes, the body has an adaptation process, and the blood pressure and heart rate are adjusted, which can avoid accidents caused by the lack of blood supply to the brain caused by suddenly getting up.
