Why is cold weather easy to induce sudden death?

Cold weather is the devil period of cardiovascular and cerebrovascular diseases, and it is also the high incidence period of cardiovascular and cerebrovascular diseases, especially for the elderly with hypertension, hyperglycemia and dyslipidemia. Most of the blood vessels in their bodies have hardened. In addition, the human body's "blood is cold and coagulated, and warmth is warm." After decades of life, the blood is thick, with many impurities, heavy ions and grease. Cold weather can stimulate vasoconstriction, slow blood flow, increase blood pressure in a short time, increase the load on the heart and brain, stimulate cardiovascular and cerebrovascular spasm, and form thrombus after platelet aggregation, leading to stroke and myocardial infarction, so it is very easy to cause sudden death.

How to prevent the attack of cardiovascular and cerebrovascular diseases in winter? Please do the following:

First, when the temperature difference between indoor and outdoor is large, try to reduce going out. Keep your head, back and feet warm when you go out.

Second, winter is a good time for body tonic, but for patients with cardiovascular and cerebrovascular diseases, low salt, low fat and low cholesterol, eating more corn beans, kelp, vegetables and fruits, onions, garlic and other foods can reduce the intake of fat and cholesterol and stabilize blood pressure.

Third, drinking water can accelerate the internal circulation of the body and is also one of the ways to prevent cardiovascular and cerebrovascular diseases. It is suggested to drink a cup of warm water on an empty stomach after getting up in the morning, which can dilute the blood and reduce the chance of stroke and myocardial infarction in the morning.

Fourth, avoid emotional excitement and keep an optimistic attitude. Emotional excitement leads to increased adrenal secretion, increased vasoconstriction, accelerated heartbeat and elevated blood pressure, which will lead to increased heart load and coronary artery spasm.
