There is usually a slight increase after bathing. Bathing itself is a kind of activity and the influence of the water temperature will accelerate blood circulation, increase the burden on blood vessels and the heart, which may lead to a temporary increase in blood pressure, but a little rest can usually return to normal. It is recommended that patients with high blood pressure should not set the water temperature too high or too low when bathing, and the bathing time should not be too long. If the patient’s blood pressure does not drop after bathing and is accompanied by physical discomfort, oral blood pressure-lowering medications, such as metoprolol succinate and nifedipine, can be taken under the guidance of a doctor. Patients with persistent non-decrease in blood pressure are advised to go to the hospital in time. And under the guidance of the doctor to take drugs, not self-medication. Usually pay attention to a healthy diet, reduce the intake of greasy food as well as salt-containing intake, and at the same time, appropriate physical exercise can help restore blood pressure.
