Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure occurs when this pressure rises and stays high over time, which can damage the heart and other parts of the body in many ways. Adults should aim for a blood pressure reading of 120/80 mmHg or lower.
