At the turn of autumn and winter, the number of patients visiting hospitals for cerebral infarction or re-occurrence of cerebral infarction increases significantly. So, in the cold season should be how health care to prevent cerebral infarction, so that they can safely through the winter? 1, do not crave food, to prevent “disease from the mouth” In order to resist the winter wind and cold, people need to take in more calories, so there is a significant increase in various meat foods on the table, such as shabu-shabu, roast meat, etc., which will increase the risk of hyperlipidemia, atherosclerosis. Here we draw the attention of middle-aged and elderly people to pay attention to the reasonable combination of winter tonic, in addition to additional meat food on the table, daily fruits and vegetables can not be missing. It is also important to give a warning to those elderly people who prefer hot pot, especially those who are fat or have been found to suffer from hypertension, hyperlipidemia, atherosclerosis, restaurant hot pot ingredients salty, after the meal due to the large amount of water is easy to increase blood volume, aggravating hypertension. Therefore, do not overly pursue taste when eating and should use less seasoning. In addition, after eating shabu-shabu, blood lipids increase in a short period of time, and the viscosity of the blood increases, which can induce acute cerebral infarction, so you should choose less fatty beef, fatty lamb, fatty intestines, etc., and can choose more fish and other seafood. 2, drink more water to reduce blood viscosity Increase the amount of water, especially should not excessively control the intake of water before bed. Studies have shown that cerebral infarction is most likely to occur at dawn and just after waking up, because at this time the blood viscosity is large, easy to form clots blocking blood vessels. Some elderly people start to control water intake after dinner in order to reduce the number of times they get up at night and sleep well, thus increasing blood viscosity. Winter is a relatively dry season of the year, coupled with winter heating, the air humidity in the room is not enough to limit drinking water will make the water in the blood more inadequate, increasing the chance of stroke. Therefore, elderly people should not restrict water excessively before 8:00 pm. For those who do urinate a lot at night or have facial edema when they get up the next day and should not drink water at night, they can also use the measure of slowing down the waking up action and drinking a glass of warm water first after getting up in the morning. It should be reminded that drinking water before going to bed does not include drinking tea or coffee or the like, because it has a diuretic effect, will promote the discharge of water, increasing blood viscosity. In addition, if you take a bath, you should drink a glass of water before and after the bath to replenish the water lost in the body due to the bath. 3, dress warmly, especially at night to pay attention to the elderly to the environment temperature tolerance significantly reduced, in the case of cold stimulation, adrenal secretion activity will increase, prompting blood circulation to speed up to resist the cold. But at the same time, the increase of hormones secreted by adrenal glands will cause vasoconstriction and increase blood pressure, and the high blood pressure will cause brain hemorrhage, and the accelerated blood flow has the risk of blocking the cerebral blood vessels by dislodging atheromatous plaque. In addition, the cold air will make the blood vessels suddenly shrink, the lumen becomes thin, if the lumen has a large number of lipid deposits and hardened plaque, it is easy to make the blood flow is blocked. Especially at night, when thinly dressed to leave the warmth of the nest to get up, this cold stimulation will be more obvious. Therefore, in winter, in addition to the elderly should be timely increase and decrease clothing according to the temperature changes to avoid getting cold, should pay more attention to keep warm when getting up at night. 4, diligent activity, happy mood is very important The cold winter wind will make most of the elderly choose indoor activities, exercise significantly reduced. In addition, winter often due to appetite, and over-eating. At this time, if the lack of exercise will reduce the amount of heat consumption, fat accumulation, resulting in obesity. In addition, the alternation of cold and warm air will also have a certain impact on people’s physiology and psychology, emotional instability, and easily induce cerebrovascular accidents. Therefore, in winter, the elderly should still adhere to outdoor exercise. This can help consume extra calories and also enhance communication with others and adjust the mentality through rich cultural and sports activities. However, the amount of exercise should not be too much and should not be drenched in sweat, but can be done by heating up the body but not yet sweating. The elderly should pay more attention to gradual and measured activities. Daily morning exercise should be arranged after the sun comes out, when the temperature will rise, so as to avoid cardiovascular and cerebrovascular accidents induced by cold air stimulation to make the blood vessels suddenly contract. 5.Observe each other, seek medical advice early if there is any new situation. People with hypertension, hyperlipidemia, coronary heart disease, diabetes, atrial fibrillation and other diseases are at high risk of stroke, so in addition to taking the appropriate medication according to medical advice, they should also take aspirin or Poliovel for a long time to prevent platelet aggregation and thrombosis. In addition to observing the symptoms of the original disease, patients and family members should also pay attention to those new symptoms, such as whether the color of the excreted stool becomes black (gastrointestinal bleeding), whether there is bleeding when brushing teeth, etc. If there are abnormal changes, they should see a doctor in time. In addition, when recurrent episodes of vertigo, tinnitus, deafness, unstable walking, slurred speech or numbness of hands and shoulders appear suddenly, it indicates the precursor of thrombosis or thrombosis has already formed, so you should seek medical treatment in time to avoid missing the best time for treatment. Some data show that the disability rate of patients with cerebral infarction treated within 3 to 6 hours of onset is 40% lower than that of those treated after 6 hours.
