The ancients regarded the tenth month to December of the lunar calendar as Mengdong, midwinter, and season winter, which were collectively called winter and "three winters". With the advent of the cold wave, cardiovascular and cerebrovascular diseases such as angina, acute myocardial infarction, and stroke have also entered the multi-incidence season, and studies have reported that for every 1 decrease in temperature, the incidence of heart disease will increase by 2%.
In traditional Chinese medicine, the normal cold in nature is called cold, and if the cold in nature is too cold or people cannot properly defend and keep warm, the cold will become one of the six evils: cold evil.
According to the principle of thermal expansion and cold contraction, the human body keeps warm by constricting blood vessels and reducing heat dissipation when it is coldIn addition, the weather is often dry in winter, which leads to an increase in blood pressure in the cardiovascular system, an increase in heart rate, blood concentration, slow blood flow, an increase in blood viscosity, an increase in cardiac oxygen consumption, and an increase in the burden on the heart, brain, kidneys and other organs. At this time, the human sympathetic nerve is excited, and the vascular endothelial function is dysfunctional, which can easily lead to vascular spasm, plaque rupture and thrombosis, etc., thereby inducing a variety of vascular diseases. Therefore, cold weather can induce cardiovascular and cerebrovascular diseases.
Winter is a time when nature is closed. Man and nature are corresponding, coherent, and should also be nurtured, nourished and recharged, and prepared for the growth and growth of yang energy in the spring of the coming year. For healthy people, we must adhere to the principle of adapting to the natural world: seclusion. The team of Professor Wu Wei of the First Affiliated Hospital of Guangzhou University of Chinese Medicine suggested that we should adhere to the eight-character health concept of "cold prevention, moisturizing dryness, collection, and nourishing yin" for cardiovascular maintenance in winter. In terms of diet, it is necessary to help yang and dispel cold, eat more vitamin-rich fruits and warm vegetables, increase the intake of high-protein, low-fat, high-nutrient foods, and drink 20ml of oral organic olive oil every day, which helps to nourish the cardiovascular system and assist in the prevention of cardiovascular diseases. Olive oil is the only 2% of the world's extra virgin olive oil, contains a variety of cardiovascular nutrients, is a healthy fat, and does not contain cholesterol, which can effectively maintain the cardiovascular system.
