A sudden drop in temperature can easily induce cerebral infarction. Do nine things actively to avoid cerebral infarction.

1. Cold weather will stimulate sympathetic nerve excitement and increase the secretion of adrenal cortical hormones, which will promote spasm and contraction of small arteries, increase peripheral vascular resistance, and increase blood pressure, which is a major risk of cerebral infarction. factor.

2. In cold weather, blood tends to become thicker and more likely to coagulate and form thrombus. Most cerebral infarctions are caused by blood clots that block blood vessels in the brain.

3. Our body's response to cold weather often puts additional stress on the cardiovascular and cerebrovascular systems as we "tighten" the blood to conserve heat and energy.

4. Researchers also found that humidity is also related to the risk of cerebral infarction. High humidity in the atmosphere can cause dehydration in some people and increase the risk of blood clots. Overall, the researchers found that the incidence of cerebral infarction was higher in winter and relatively lower in summer.

1. Avoid excessive physical activity

In winter, physical activity can be appropriately reduced. For example, people working on construction sites should pay more attention, because excessive physical activity will increase the oxygen demand of the heart and brain. The demand causes vasoconstriction, decreases cerebral blood flow, and induces cerebral infarction.

2. Keep warm

Keeping warm in winter is very important. Blood vessels also expand with heat and contract with cold. When the body is exposed to a cold environment, blood vessels will Sudden contraction may induce cerebral infarction. It is very important to wear a down jacket, hat, gloves, and scarf when going out in winter. At the same time, you should also avoid taking off your clothes quickly as soon as you enter the heated room. Large temperature differences will also affect blood vessel circulation.

3. Avoid infection

Viruses are active in winter, making it easier to get colds and flu. Especially during the COVID-19 epidemic, it is even more important to prevent and treat COVID-19 infection. Infection can cause fever, consume body water, lead to dehydration, lower blood pressure and induce cerebral infarction. The virus can also easily induce blood coagulation, form thrombus, and lead to cerebral infarction. Doctors recommend: keep warm, wear a mask, wash hands frequently, and maintain social distance.

4. Control risk factors

Risk factors for cerebrovascular disease are the main causes of cerebral infarction. Regular physical examinations are required to control blood pressure, blood sugar, blood lipids, and weight within normal ranges. First control it through diet and exercise. If the effect is not good, use medication under the guidance of a doctor.

5. Quit smoking, quit drinking or limit drinking

Smoking is harmful to all but beneficial. Tobacco contains a large number of harmful substances, such as tar, nicotine, etc. These harmful substances can damage the inner walls of blood vessels, making it easy to accumulate fat deposits, form atherosclerotic plaques, and induce cerebral infarction. Be sure to quit smoking and avoid secondhand smoke.

Long-term heavy drinking will affect the metabolism of blood lipids. Over time, blood lipids will gradually increase, which can induce cerebral infarction. If you don't drink, there is no need to start drinking; if you do drink, please drink in moderation and you can drink a little wine (referring to red wine, wine, not high-alcohol liquor or beer), red wine is the first choice because it contains resveratrol, Resveratrol is thought to protect the heart and brain.

6. Eat some warming foods in winter

Warm and pungent ingredients: such as ginger, onions, and garlic, which can dispel cold, dampness, and warmth. Stomach, promote blood circulation.

Recommended black-bone chicken soup: It is rich in protein, vitamin B family, vitamin E, etc. It benefits the liver and kidneys and promotes metabolism. Such as beef, mutton, etc., which can nourish the spleen and stomach and replenish qi and blood.

Brown sugar: nourishes blood, activates blood circulation and removes blood stasis, promotes blood circulation, and is suitable for regulating physical deficiency and coldness.

Moisturize well and drink more hot water to effectively replenish body moisture, promote blood circulation, and excrete toxins. Drinking more water can enhance metabolism, consume energy, help control weight, and reduce the risk of hyperlipidemia, which is beneficial to vascular health.

Note: Warming tonic is not suitable for people with high blood pressure.

7. Moderate exercise

The intensity of exercise in winter should be weaker than in other seasons. It is recommended to focus on indoor exercise, such as badminton, aerobics, Tai Chi, etc. For those who run all year round and are in good physical condition, they can still run outdoors and be careful to avoid catching a cold. It is recommended to exercise 150 minutes a week, 30 minutes each time.

8. Maintain emotional stability

Large mood swings, such as an impatient personality, easy to quarrel with others, or depression, mood swings, which can easily lead to guilt. Environmental disorder and large blood pressure fluctuations increase the risk of cerebral infarction. Therefore, you must have a balanced mentality and be calm when dealing with things.

9. Adequate sleep

Adequate sleep is conducive to the stability of mood and blood pressure, the balance of the internal environment, the restoration of energy, and can reduce the risk of cerebral infarction. Doctors recommend: sleep 7 to 9 hours every night and take a nap of half an hour to 1 hour.

Weakness or numbness of one limb

Numbness of one side of the face or crooked corners of the mouth

Slurred speech or inability to understand language

Eye direction Staring to one side

Loss or blurring of vision in one or both eyes

Dizziness with vomiting, balance disorder

Severe headache and vomiting that were rare in the past

Unconsciousness or convulsions

Doctor's advice: Once any of the above symptoms occur, the possibility of cerebral infarction should be considered and medical attention must be sought immediately. The earlier the treatment, the better the recovery. Don’t miss the “golden time window” of treatment, which is within 4.5 hours of onset.
