A strong cold wave increases the risk of exposure to high blood pressure, which is vulnerable to the cold. This is because the lower the temperature, the lower the metabolic activity of the body, and the higher the risk of blood pressure increase due to the contraction of blood vessels. However, most patients with high blood pressure do not experience any particular symptoms in their early stages and should manage their blood pressure by viewing the "pre-hypertensive stage" as a kind of danger signal.

According to the Korea Meteorological Administration, a "strongest cold wave" is expected after snow and rain fall across the country on the 22nd, the Lunar New Year holiday. In particular, the morning temperature in Seoul was expected to be minus 17 degrees on the 23rd, the lowest this winter.
The criteria for diagnosis of hypertension are those of adults aged 18 or older with systolic blood pressure of 140 mmHg or more or relaxation blood pressure of 90 mmHg or more. The pre-stage of hypertension refers to systolic blood pressure 120-139 mmHg and relaxation blood pressure 80-89 mmHg (less than 80 mmHg during normal blood pressure systolic 120 mmHg). From this section, the risk of developing cardiovascular diseases such as stroke, angina, and myocardial infarction, which are complications of high blood pressure, increases.
It brings out a good sleep.
Lee Hae-young, a professor of cardiovascular medicine at Seoul National University Hospital, said, "60 percent of angina, myocardial infarction and 90 percent stroke are caused by high blood pressure.
In order to measure and manage blood pressure properly, it is recommended to sit in a chair with a backrest. After that, the arm is properly bent and measured twice or more with a blood pressure meter. If you stretch your arm or clench your fist, you should be careful because your blood pressure may rise higher than it actually is.
When measuring blood pressure at home, it is recommended to measure blood pressure once in the morning and once in the evening. Usually, blood pressure is 20-30 mmHg higher in the evening than in the morning. The family blood pressure level corresponding to 140/90 mmHg, which is the standard for diagnosis of hypertension in the clinic, is known to be 135/85 mmHg.
Risk factors for high blood pressure include age, family history, drinking, smoking, old age, lack of exercise, obesity and eating salty food. The primary goal of treating hypertension is to lower blood pressure to 140mmHg during systolic period and 90mmHg during relaxation period, thereby reducing the incidence and mortality of cardiovascular disease. If you have diabetes or your kidney is not in good condition, you should manage it more thoroughly and adjust it to 130mmHg during systole and 80mmHg during relaxation.
In order to minimize the side effects of using only one drug, the most effective treatment for hypertension is to complement each other with two or more drugs.
Regular exercise and restrictions on salt intake can maximize the effectiveness of the drug and increase the possibility of reducing the dosage. If you lose about 5kg or cut salt intake in half, you can control blood pressure by about one tablet of blood pressure, which can further improve the effectiveness of blood pressure medicine. If you want to stop taking blood pressure drugs, you should consult a specialist to decide. This is because 70 percent of patients who take high blood pressure medication and stop taking high blood pressure medication are reported to have high blood pressure again.
Recently, "electrode ceramic resection" has been developed, which uses ultrasonic waves and electromagnetic waves to extinguish kidney blood vessels with a heat of about 60 degrees Celsius to relieve the effects of the tension hormone (sympathetic nerves). The procedure is performed in patients with high blood pressure, which is difficult to control.
To prevent high blood pressure, it is helpful to reduce salt intake such as salt and soup and develop a habit of eating lightly. Weight loss through regular exercise is also effective in lowering blood pressure. Exercise lowers blood pressure, improves cardiopulmonary function and hyperlipidemia, and is beneficial to patients with high blood pressure.
Smoking and drinking are especially important risk factors for elevated blood pressure and cardiovascular disease, so quitting smoking and drinking alcohol are essential for preventing high blood pressure. Professor Lee stressed, "Prevention of high blood pressure is an investment in the future that can prevent myocardial infarction, stroke, and heart failure that can occur in the future, and should be managed steadily."
