With the coming of autumn and winter, cardio-cerebrovascular diseases have also entered a high incidence period.

This is because the temperature difference between the morning and evening in autumn and winter is large, and the weather is dry, and the human body needs to consume a lot of water to breathe. At this time, if not enough water can be replenished, the blood viscosity will be too high, which will lead to poor blood circulation and blood vessel blockage.

Therefore, the autumn and winter season has become the high incidence season of cardio-cerebrovascular diseases every year. What is the impact of autumn and winter season on our blood vessels and how to prevent it? Let's have a look!

1. Increased incidence rate of cardiovascular and cerebrovascular diseases

The temperature drops suddenly. In order to reduce the heat dissipation of the skin and keep warm, our blood vessels will contract, resulting in the increase of blood pressure. On the one hand, the previously hardened arterioles will rupture due to the inability to withstand the strong internal pressure, leading to the occurrence of cerebral hemorrhage; On the other hand, it increases the burden on the heart and the probability of angina pectoris and myocardial infarction. 

Precautions:

Research shows that the temperature decreasesAt 10 ℃, the risk of heart disease increases by 7%. Therefore, it is important to increase clothing according to the temperature change, especially in winter when the temperature difference between indoor and outdoor is large; Pay attention to the water temperature when washing and bathing in cold weather to avoid irritation.

2. Increased incidence rate of hyperlipidemia

In cold weather, people are more willing to drink and eat high-calorie food in order to keep warm from the cold. At the same time, the amount of outdoor activities is significantly reduced, resulting in increased blood lipids, which is an important risk factor for cardiovascular and cerebrovascular diseases. 

Precautions:

In autumn and winter, we should also maintain a healthy lifestyle, eat a light diet, achieve low salt, low fat and low sugar, eat more high-quality protein and carbon water, eat more vegetables and fruits, reduce alcohol consumption, maintain proper exercise, and stay away from animal viscera and fat with high cholesterol content such as oil, smoking, curing, etc.

3. Unstable blood pressure

Cold weather and large temperature difference between day and night can easily lead to unstable blood pressure, especially when moving from warm indoor to outdoor, the change of temperature will lead to sharp contraction or relaxation of blood vessels, thus making blood pressure fluctuate greatly.

The fluctuation of blood pressure is also an independent risk factor of hypertension combined with cardio-cerebrovascular diseases, which will lead to a significant increase in the occurrence of cardio-cerebrovascular accidents, such as acute myocardial infarction, angina pectoris, cerebral infarction, cerebral hemorrhage, etc.

Precautions:

In the cold autumn and winter season, patients with hypertension should pay special attention to keeping warm, and do a good job of blood pressure monitoring. If there are large fluctuations in blood pressure or discomfort symptoms such as dizziness and chest tightness, they must go to the hospital in time to see a doctor. 

4. Respiratory infection

Strong cold air will dry the local mucosa of the nose and throat, causing the mucosa to rupture easily, thus making various pathogenic viruses take the opportunity to enter, leading to respiratory tract infection.

However, once respiratory tract infection occurs, especially lower respiratory tract infection will lead to the decrease of oxygen saturation, and the body will be in a state of relative hypoxia, which will lead to the decline of the function of tissues and organs of the whole body, dizziness, weakness, drowsiness, chest tightness, suffocation and other uncomfortable symptoms, and even lead to acute myocardial infarction, stroke and other cardiovascular and cerebrovascular diseases.

Precautions:

In order to prevent respiratory tract infection, in addition to daily warming work, it is very important to do a good job of protection when going out, especially during the epidemic, wear masks, avoid gathering in densely populated areas, and wash hands frequently to maintain good personal hygiene.
