Blood pressure values of 120/80 mm Hg or less are considered normal. During exercise, systolic blood pressure may temporarily increase by 20-30mm Hg, but decrease within minutes of completing the workout. Studies show that a very fit person who exercises regularly will have lower resting blood pressure (usually less than 120/80 mm Hg) than someone who leads a sedentary lifestyle. Regular physical activity can strengthen your heart. When your heart is stronger, it can pump more blood without less effort. Exercise also triggers the secretion of nitric oxide in the lining of the arteries, which keeps blood vessels elastic and allows blood to flow more easily. Therefore, adding moderate physical activity to your daily routine can help keep your blood pressure healthy.
Blood pressure is the pressure of the blood circulating against the walls of the blood vessels. This measurement, usually done with a stethoscope, a pressure gauge, and an inflatable cuff wrapped around an arm, provides a quick indication of a person’s health status. Blood pressure wristbands need to be properly applied and inflated to accurately measure blood pressure. Blood pressure is measured in millimeters of mercury – written as mmHg – because, historically, blood pressure calculations were done using a mercury column displaced by heart rate-generated pressure and measured in millimeters. Today, digital blood pressure machines are capable of automatically calculating blood pressure accurately.
Hypertension, also known as hypertension, is a common disease that develops when blood flows through the arteries at a higher than normal pressure. Your blood pressure is made up of two numbers: systolic and diastolic. Systolic pressure is the pressure when the ventricles pump blood out of the heart. Diastolic pressure is the pressure between heartbeats when the heart fills with blood. Your blood pressure changes throughout the day based on your activities. For most adults, normal blood pressure is below 120 over 80 millimeters of mercury (mm Hg), which is your systolic pressure reading versus your diastolic pressure reading – 120/80 mm Hg. Your blood pressure is considered high if you have consistent systolic readings of 130 mm Hg or higher or diastolic readings of 80 mm Hg or higher.
