In the blink of an eye, it was the coldest year of the year. At this time we need to pay attention to keeping warm, otherwise we may catch the cold without care, which may cause cardiovascular disease.
High incidence of cardiovascular disease in winter
Cardiovascular disease can occur in any season, but its incidence is higher in winter. Why?
First, the temperature in winter is relatively low. After the human body is stimulated by cold, the blood vessels will contract, resulting in an increase in blood pressure. However, vascular sclerosis in the elderly is more common, cannot contract normally, and has poor adaptability. Under cold stimulation, blood pressure rises faster and cardiovascular disease is more likely to occur.
Second, the winter temperature is low, people usually have less outdoor activities, human metabolism will slow down, blood circulation slows down, blood vessels are more likely to be blocked, and cerebral infarction will be more common.
Third, respiratory diseases such as colds and pneumonia are prone to occur in winter. These diseases will increase the burden on the heart and increase the incidence of cardiovascular diseases.
Vitamin D may be beneficial for cardiovascular health
Cardiovascular diseases, hypertension and other diseases may be related to vitamin D deficiency. Lack of sufficient sunlight and outdoor activities in winter, can not be supplemented with enough vitamin D through sunbathing.
Especially in the elderly, the function of various organs and tissues deteriorates, the synthesis of vitamin D in the body is poor, and the intake of vitamin D during the diet is not good, which eventually leads to the lack of vitamin D in the human body.
Studies have shown that the low level of vitamin D is related to the mortality of various cardiovascular diseases and is one of the risk factors for cardiovascular disease. Studies indicate that vitamin D may protect the cardiovascular system by affecting or regulating vascular calcification, renin, and angiotensin. Vitamin D may also improve blood lipid metabolism by inhibiting the secretion of parathyroid hormone.
Prevention of cardiovascular diseases in winter
First, if you want to prevent cardiovascular disease in winter, you must pay special attention to the issue of warmth. When cooling down, pay attention to adding clothes in a timely manner, and choose clothes that have good warmth but are relatively loose and comfortable.
Secondly, develop a reasonable diet and living habits, avoid touching alcohol and tobacco, avoid overwork, and usually pay attention to vitamin D supplements, such as taking Letervijian calcium vitamin D, you can also supplement Letervijian Coenzyme Q10 to protect the heart.
Third, maintain emotional stability. Keep your emotions relaxed and happy, avoid sudden anger, sadness, etc. Don’t have similar emotional changes like big ups and downs, because this is likely to cause blood pressure to rise.
Fourth, exercise appropriately to improve the body’s ability to protect against the cold. Pay attention to the moderate amount of exercise, you can choose to take a walk, brisk walking, yoga and other peaceful sports.
Fifth, pay close attention to your physical condition. People with cardiovascular problems need to pay close attention to changes in the condition, check regularly, and use medicine to control if necessary.
