First, the weather is getting cold, why does blood pressure rise?
When the weather is cold, in order to resist the cold, the human body will secrete catecholamine, mainly adrenaline, which will lead to vasoconstriction. It can also be understood as the principle of thermal expansion and cold contraction. When the weather gets cold, blood vessels contract. Blood pressure is the pressure of blood on the blood vessel wall. As blood vessels contract smaller, the pressure will naturally increase.
Second, in the face of cold weather, how should the majority of hypertensive patients respond?
1. Strengthen blood pressure monitoring.
It turns out that when blood pressure is stable, it may be measured several times a week. Be diligent in winter. You might as well take your blood pressure every day. Generally, it is enough to test twice a day, once after getting up in the morning and once before going to bed at night.
2. If the blood pressure is unstable, adjust the medicine in time.
Winter is also the peak time for hypertensive patients to go to the hospital to adjust their medicines. It is normal to add medicine in winter and reduce medicine in summer. So how much does blood pressure rise before you need to adjust the drug? I think the blood pressure fluctuates more than 10mmHg, and it needs to be measured several times continuously, but this shows that it is not a measurement error. You should see a doctor, increase the dose, or change the medicine.
keep warm
Because of the cold weather, blood pressure fluctuates easily, so it is very important to keep warm. In particular, some elderly people who like to exercise in the morning can consider going out later or changing to the evening.
4. Pay attention to keeping weight
Winter is the season of gaining weight. If you eat in winter, you don't move much and get fat easily. Obesity is very harmful, so we should pay attention to weight control.
Step 5 diet
In cold weather, eating a hot pot is excellent. But the spicy soup base and sauce are too salty for patients with hypertension. Patients with hypertension should not eat too salty, consider clear soup.
Summary: Sudden increase of blood pressure can easily lead to rupture of intravascular arterial plaque and thrombosis. The rupture of cardiac vascular plaque leads to myocardial infarction, and the rupture of cerebral arterial plaque leads to cerebral infarction. This is also the reason for the increase in the incidence of these diseases in winter. Therefore, when winter comes, all patients with hypertension should be vigilant. If chest pain, crooked face, crooked mouth, numbness of hands and feet occur, they should seek medical advice in time.
