For patients with high blood pressure in winter, it is advisable to increase the dosage of antihypertensive medication sensibly. Blood pressure is the pressure on the inner wall of the blood pressure caused by the natural flow of blood through the blood vessels. Blood pressure is divided into systolic and diastolic blood pressure, and its level depends on cardiac output and peripheral arterial vascular resistance. And since the weather is colder in winter, the stimulation of cold causes peripheral blood vessels to constrict and peripheral resistance to increase, which in turn causes an increase in blood pressure. For patients with high blood pressure in winter, the dosage should be adjusted if necessary in order to smooth the dosage of the drug to control the blood pressure. If the blood pressure is high in winter, it is recommended to consult a doctor in time for standardized treatment, and not to adjust the medication or even stop the medication on your own.
