Why are you prone to cardiovascular and cerebrovascular diseases in winter?

Winter is the season when many diseases are most common, especially cardiovascular and cerebrovascular diseases. So, why are cardiovascular and cerebrovascular diseases more common in winter, and what should we pay attention to?

1. Cold can easily cause cardiovascular and cerebrovascular diseases

The main reason for the high incidence of cardiovascular and cerebrovascular diseases in winter is that cold will constrict the blood vessels of the human body and reduce sweating, thereby stimulating blood pressure. rise. The human body will experience sympathetic nerve excitement, accelerated blood flow, increased peripheral resistance of blood vessels, leading to increased blood pressure or vascular embolism. In addition, people’s activity level decreases when it’s cold. The blood perfusion of the brain, myocardium, and internal organs is also reduced, which is also one of the reasons for the high incidence of cardiovascular and cerebrovascular diseases.

2. How to prevent cardiovascular and cerebrovascular diseases in winter

1. A reasonable diet is conducive to the prevention of cardiovascular and cerebrovascular diseases

There should be reasonable measures for the prevention and treatment of cardiovascular diseases Diet arrangement, hyperlipidemia, unbalanced diet, diabetes and obesity are all related to dietary nutrition. In principle, the "Three Lows" should be achieved: low calories, low fat, and low cholesterol. And actively control your weight through a reasonable diet. Research shows that a 10% increase in body weight increases the risk of coronary heart disease by 38%; a 20% increase in body weight increases the risk of coronary heart disease by 86%. Therefore, controlling diet is an important condition for preventing cardiovascular and cerebrovascular diseases.

The correct diet for cardiovascular and cerebrovascular patients should be mainly light and eat more fresh green leafy vegetables and seasonal fruits. Increase the fiber diet, that is, eat more whole grains, dry beans, vegetables, fruits, etc. Try to reduce the intake of fat and cholesterol, such as animal brains, offal, egg yolks, etc. Some people think that seafood is safer, but in fact some seafood has higher cholesterol content, such as crabs, scaleless fish, etc. You should eat less of these seafood. Generally speaking, foods that protect the heart and brain include barley, kelp, celery, fungus, oats, beans, spinach, walnuts, almonds, etc. You should eat more of them in your daily life. These foods contain a large amount of VE and VB6.

2. Appropriate exercise is helpful in preventing cardiovascular and cerebrovascular diseases

The climate is cold in winter, and many people reduce outdoor activities. In addition, they are accustomed to eating a lot of fish and meat, which can easily lead to a significant increase in weight. Obesity can easily induce high blood pressure. If blood pressure is not well controlled and allowed to develop, some very dangerous diseases such as myocardial infarction, sudden cardiac death, etc. will come to your doorstep. In the prevention and treatment of cardiovascular and cerebrovascular diseases, people should actively participate in moderate physical exercise. Regular and appropriate exercise is helpful to enhance heart function and promote normal metabolism of the body. An appropriate amount of physical activity can help increase blood circulation, enhance resistance, increase the oxygen content of various organs, and improve the functions of various organs throughout the body. While exercising appropriately, you can also take some drugs that increase the oxygen content of the myocardium, which not only helps to increase blood circulation, but also significantly improves the body's ability to tolerate hypoxia, especially increasing the oxygen content of the myocardium, which can better prevent and treat the heart and brain. Vascular disease. Some elderly people like to get up early for morning exercises, but the morning in winter is the time when the temperature is the lowest of the day. When they get out of the warm bed and go outdoors, the temperature difference is too large. Cold weather will cause cardiovascular contraction, which can easily cause disease attacks. For cardiovascular patients, keeping warm in winter is very important. Generally speaking, if time permits, especially for the elderly, you can go outside for a walk at three or five o'clock in the afternoon and do some appropriate exercise. It is also necessary to control the amount of exercise and not increase the burden on the heart.
