Low temperature in winter reduces the elasticity of blood vessels on the body surface and increases the peripheral resistance; Cold can stimulate sympathetic nerve excitement, increase adrenaline secretion, thus causing arteriole contraction and blood pressure increase; Cold can also increase the concentration of fibrinogen in the blood, which is easy to cause thrombosis. So the incidence of stroke in winter is high. How can we prevent it? Prevention can be carried out from the following aspects:

First, pay attention to keep warm: cold protection Add clothes in time with climate change, especially to prevent staying in a cold environment for too long, don't walk against the cold wind, and strengthen the warmth of hands, feet and face. The indoor temperature should be kept at 18 ~ 24 degrees Celsius.

Second, proper exercise: In order to make the functional activities of all parts of the body normal, keep regular exercise every day, such as walking and doing exercises for at least 30 minutes. This is a good way to lower blood pressure in patients with mild to moderate hypertension.

Third, treat chronic diseases:

According to statistics, the incidence of stroke in diabetic patients is 2 1 times higher than that in normal people;

Patients with heart disease, chronic bronchitis, hypertension and hyperlipidemia are 2 ~ 5 times higher than normal people.

So we should actively treat chronic diseases. Hypertension is the most dangerous factor leading to cerebral hemorrhage and stroke. The higher the blood pressure, the greater the possibility of stroke. The longer hypertension lasts, the greater the risk of stroke. If you have hypertension, it is very important to treat it seriously, control the fluctuation and increase of hypertension and reduce the occurrence of stroke.

Fourth, pay attention to diet control:

Don't eat too salty. Eat more fresh vegetables and fruits to increase vitamins, inorganic salts and trace elements, and eat more foods containing more fiber. Pay attention to supplement protein, such as eggs, lean meat, fish and bean products. At the same time, it is necessary to achieve low fat, less salt and no excess. Limit foods with high fat and cholesterol content, such as fat, animal fat, animal offal, cream, roe, etc. To prevent hyperlipidemia, hypercholesterolemia, obesity, hypertension and arteriosclerosis.

Take it actively, such as green onion, garlic, onion, leek, alfalfa, auricularia, kelp, mushroom, laver, wine, celery, spinach and other protective foods rich in flavonoids and folic acid, which have antioxidant and homocysteine inhibition effects.

Fifth, don't overeat. After a full meal, the blood is redistributed, most of the blood flows to the gastrointestinal tract, cerebral transient anemia, and blood flow changes lead to cerebral thrombosis and stroke. Therefore, eat in moderation, don't eat too much, and it is best to eat 80% full every meal.

Sixth, stabilize the mood. There are13 stroke patients who suddenly get sick because of anger, quarrel, anger and excessive excitement. Therefore, patients with hypertension should maintain an optimistic attitude, stabilize their emotions, and make psychological self-adjustment at any time, and don't idle, sulk and lose their temper. When you encounter troubles or problems, you should talk to your intimate friends to prevent yourself from being withdrawn, sad and desperate, and you should not be agitated and excited to prevent cerebral vasospasm and create conditions for cerebral thrombosis.

Seventh, long-term or large-scale abstinence from smoking and drinking will accelerate the heart rate and induce cerebral hemorrhage. Nicotine in tobacco can constrict small blood vessels, increase blood pressure and blood viscosity, leading to thrombosis and stroke.
