Why is it cold and blood pressure high?

Blood vessels have the characteristics of "expansion with heat and contraction with cold", that is, blood pressure will rise when blood vessels contract with cold; When the weather is hot, blood vessels dilate, leading to a drop in blood pressure. There are many patients with hypertension, who are generally long-term drinkers. As long as you are diagnosed with hypertension, you need to take medicine for a long time to control your blood pressure. Many hypertensive patients find that the colder the weather, the higher their blood pressure, and they take more drugs than when the weather is warm. What is the reason of cold weather and high blood pressure?

Some patients with hypertension have relatively good blood pressure control, but when the temperature drops, their blood pressure rises again, and patients begin to wonder whether their condition is serious or antihypertensive drugs are ineffective. In fact, hypothermia and blood pressure rise are inevitable phenomena.

When the weather suddenly gets cold, or the temperature difference between morning and evening is very large, the blood pressure fluctuation will be more obvious. Generally speaking, in winter, the blood pressure of patients with hypertension will increase by 5 5- 10/0mmhg, and the highest can even reach 20mmhg. On the other hand, due to the poor elasticity of blood vessels, the main feature of the elderly is the increase of systolic blood pressure, that is, hypertension. Hypertension in young people is mainly caused by high vascular resistance. In winter, with the increase of diastolic blood pressure (that is, low pressure), vascular resistance increases slightly.

First of all, how to deal with the high blood pressure in cold weather? 1. Cold weather and high blood pressure are not drugs. Patients should not panic and change dressings in a hurry. As long as blood pressure continues to rise above 20 mm Hg, drugs must be adjusted. It is suggested that patients in the range of 20 mm Hg can consult a doctor to take dosage or medicine to avoid greater blood pressure fluctuation. 2. Develop a good habit of monitoring blood pressure. If the blood pressure is relatively stable, test 1-2 times a week, and you can choose to test before taking medicine for the first time every day. If your blood pressure is unstable, you can choose to measure your blood pressure before each medication. People like to eat all kinds of hot pot in cold weather, including spicy hot pot, spicy hot pot, meat brush hot pot and so on. These foods are too salty for patients with hypertension, so try to eat less or less. If you feel that the taste of your daily diet is weak, it is recommended to add seasonings such as vinegar, mustard, sesame oil and onion to enhance the taste, instead of monosodium glutamate, soy sauce and Chili sauce. 4. Cold weather will raise blood pressure. At this time, patients should pay more attention to keep warm, avoid going to places with extremely low temperatures, and don't stay outdoors for a long time. When the weather is cold, patients with unstable blood pressure should not go out for morning exercise. They should have regular work and rest, combine work and rest, and avoid excessive fatigue.
