In general, soaking hot water feet does not cause the body’s arterial circulation blood pressure (systolic and or diastolic blood pressure) to rise. Blood pressure is the lateral pressure per unit area of blood vessel wall caused by the flow of blood pressure in the body’s blood vessels, is the impetus for the flow of blood pressure in the blood vessels, including systolic pressure, diastolic pressure and pulse pressure. The change of blood pressure is affected by peripheral resistance, heart rate, and per-pulse output, such as blood pressure will rise after strenuous exercise. So for people with high blood pressure or suffering from hypertension, it is possible to soak warm water feet in moderation. But soaking warm water feet for clinical hypertension does not have any therapeutic effect, but can relieve fatigue, improve sleep. Hot water foot soak should pay attention to the water temperature is appropriate, not too high. Hot water foot soak does not have any effect on the elevation of blood pressure, so if there is a low blood pressure, it is recommended to go to the cardiovascular clinic as soon as possible, under the guidance of the doctor to standardize the treatment, and should not be self-treatment, so as not to delay the condition.
