The blood circulating in the blood vessels exerts a force on the wall of the vessel. If your arteries are narrow and rigid, there will be more pressure exerted on them by the pumping action of the heart. When the pressure is too high, it negatively impacts your health.
High blood pressure has become a normal lifestyle condition amongst most of the city-bred people. It used to feature in the medical history of a person only after the age of 40. however, with increase in the pace of life and other lifestyle factors like stress, poor dietary habits and lack of exercise, younger people are falling prey to this disease.
