Pay attention to warmth and insist on drinking more water. Experts say that the elderly should increase or decrease their clothes according to the weather changes; avoid washing their faces with cold water to avoid the sudden stimulation of cold water and induce angina; apply warm water when doing laundry and washing dishes. The indoor temperature should preferably be 18~25℃, the temperature difference between indoor and outdoor should not be too big, and the room should be ventilated frequently. Winter is relatively dry, coupled with winter heating, the air humidity in the room is not enough, especially at night the blood flow in the body is slow, so the elderly should not worry about getting up at night and excessive water restriction, but to increase the amount of water to reduce the blood viscosity. 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 blood clots blocking blood vessels. Some elderly people start to control the amount of water they drink after dinner in order to reduce the number of times they get up and get a good night’s sleep, unaware that it increases the viscosity of the blood and increases the chance of a stroke. Pay attention to the monitoring of blood pressure and rational use of drugs The vasoconstriction caused by cold weather can lead to increased blood pressure, cerebrovascular blood supply and other conditions, patients with cerebrovascular disease should regularly monitor blood pressure. To actively control blood pressure, hypertensive patients with high blood pressure fluctuations try to take long-acting antihypertensive drugs, and elderly patients may need a combination of more than 2 antihypertensive drugs to control blood pressure. People with hypertension, hyperlipidemia, coronary artery disease, diabetes, atrial fibrillation and other diseases are at high risk of stroke, so in addition to taking the appropriate medications as prescribed by the doctor, they should also take aspirin or Poliovel for a long time to prevent platelet aggregation and thrombosis. Pay attention to the adjustment of diet and peace of mind Eat more light food that is easy to digest and rich in nutrients. In winter, you can take dietary supplements to keep warm and unblock blood vessels. For example, eat less cold and raw food and more warm food. In addition, it is necessary to master the scale of consumption of various meat foods, such as hot pot, roast meat, etc.. Meat food is likely to cause an increase in blood lipids in a short period of time, and the viscosity of the blood increases, which can trigger acute cerebral infarction. To maintain a calm state of mind. Emotional excitement is a big taboo for cerebrovascular disease, high blood lipids, cerebrovascular disease patients in particular should be relaxed, do not let the emotional ups and downs too much, so as not to easily induce cerebrovascular accidents. Exercise should not be too early and not too much In winter older people should still insist on outdoor exercise. This can help burn excess calories as well as 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, as long as the body is warm but not yet sweaty. 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. After winter, the elderly should pay special attention to some changes in themselves, such as headaches, vomiting, and impaired physical activity, which may be precursors to cardiovascular and cerebrovascular disease. In addition, when recurrent vertigo, tinnitus, deafness, unstable walking, slurred speech or numbness of hands and shoulders suddenly appear, it should be mentioned as a precursor of thrombosis or thrombosis has already formed, and timely medical treatment should be sought.
