Standing for a long time does not usually increase blood pressure. Clinically, blood pressure is mainly the pressure on the side walls of blood vessels caused by the flow of blood. Normally, the normal value of blood pressure is 120/80mmHg for a normal adult in a quiet state. Generally, after a change in body position, such as changing from sitting to standing, the blood pressure may fluctuate to a certain extent. However, standing for a long period of time does not cause an increase in blood pressure. In addition, smoking, working in a stressful occupation, living in a noisy environment for a long period of time, consuming too much sodium, high protein foods, drinking alcohol, or gaining weight rapidly, or taking birth control pills may all lead to an increase in blood pressure. If abnormal blood pressure occurs, it is recommended to visit a cardiovascular medicine department in time for treatment under the guidance of a doctor.
