Autumn has arrived once more, and winter's approach grows ever nearer. The cold, dry conditions of autumn and winter, coupled with significant temperature fluctuations between morning and evening, make this season a high-risk period for cardiovascular and cerebrovascular diseases. Acute cardiovascular and cerebrovascular incidents invariably stem from vascular blockages. Therefore, maintaining vascular health and preventing blockages during autumn and winter is particularly crucial.Why are blood vessels prone to blockage in autumn and winter? The cold weather and significant temperature fluctuations between day and night trigger the release of catecholamines in response to cold exposure. Catecholamines are vasoconstrictors that cause blood vessels to narrow. Additionally, reduced physical activity due to the cold environment slows blood flow, increasing blood viscosity. Combined with platelet aggregation,The combined effect of these factors makes blood vessels highly susceptible to blockage.
Doctors share 4 key points for maintaining vascular health in autumn
1. Manage the "three highs"
Individuals with hypertension, hyperglycemia, and hyperlipidemia should be particularly vigilant. These conditions can lead to atherosclerosis, a primary cause of vascular blockage. Therefore, effective management of the "three highs" is essential.Ensure medications are taken on schedule, undergo regular monitoring, and strive to maintain levels within the normal range. 2. Stay Warm and Exercise Moderately Avoid exposing blood vessels and the body to intense cold, which can cause vasospasm and constriction leading to embolism. Therefore, prioritize warmth during autumn and winter.Choose mild aerobic exercises during favorable weather periods. Physical activity generates body heat, accelerates blood circulation, and prevents vascular blockages caused by slowed blood flow. 3. Light Diet and Adequate Hydration Autumn and winter bring dry weather, increasing the risk of dehydration. Insufficient hydration raises blood viscosity, making blood vessels more prone to blockages.Therefore, active hydration is crucial during these seasons. For individuals with normal heart function, daily water intake of at least 1500-2000ml is recommended.
While the saying "winter is for nourishing the body" exists, this practice is unsuitable for the elderly and those with cardiovascular or cerebrovascular diseases. These groups should focus on light, balanced meals, consuming more vegetables and fruits while minimizing spicy, greasy, fried, and raw/cold foods.Avoid overeating at dinner to reduce blood lipids and prevent vascular blockages.
4. Improve Lifestyle Habits
Quitting smoking and limiting alcohol consumption are essential. Ensure adequate sleep, practice stress reduction, and maintain an optimistic, positive mindset. Epidemiological data indicates smoking increases the incidence and mortality of coronary heart disease by 2-6 times, with a linear positive correlation to the number of cigarettes smoked.Regarding alcohol consumption, while some studies suggest moderate drinking may increase levels of "good cholesterol" (HDL-C), it is not recommended for CHD patients. This is because CHD requires long-term medication, and alcohol interferes with drug metabolism. Drinking may cause abnormal drug metabolism, affecting treatment efficacy.Additionally, drinking often involves consuming numerous dishes, inevitably increasing fat intake—which is detrimental to CHD management. Therefore, alcohol consumption is not recommended.
Vascular-Protective Foods
Eggplant
Eggplant acts as a vascular softener, aiding cardiovascular protection and blood pressure reduction. This stems from its vitamin P content—a flavonoid compound renowned for softening blood vessels and enhancing their elasticity. This naturally prevents vascular rupture and bleeding.
Black Beans
Black beans promote blood circulation and are a common food in our daily lives. They not only improve hair quality but also enhance blood flow and boost metabolism. Additionally, black beans contain polyphenols, which help cleanse the blood and naturally prevent cardiovascular diseases.
Green Tea
Green tea is crucial for regulating blood pressure and blood sugar. Rich in catechins, it prevents blood oxidation, significantly aiding blood pressure and glucose metabolism while lowering cholesterol. Studies show daily tea consumption enhances nutrient absorption from the blood.
