About this calculator

Overview

Blood pressure is the measure of the force that your heart uses to pump blood around your body. It is given by two numbers: Systolic pressure (the force when your heart beats) and Diastolic pressure (the force when your heart rests between beats). Consistently high blood pressure, or hypertension, puts extra strain on your blood vessels, heart, and other organs, such as your brain and kidneys.

Pro Tips

Rest for at least 5 minutes in a comfortable, seated position before taking your blood pressure reading.
Don't smoke, drink caffeine, or exercise for 30 minutes before your measurement.
Keep your arm supported on a flat surface (like a table) and at heart level during the reading.
Taking multiple readings over several days provides a much more accurate picture of your average blood pressure than a single measurement.

Fun Facts

"High blood pressure is often called the 'Silent Killer' because it typically has no obvious symptoms while it causes damage to your cardiovascular system."
"Blood pressure isn't fixed; it changes throughout the day based on your stress levels, physical activity, and even what you've recently eaten."
"Salt (sodium) is a major driver of high blood pressure because it causes your body to hold onto more water, increasing the volume and pressure of blood in your system."
"The 'White Coat Effect' is a real phenomenon where patients experience higher blood pressure readings in a clinical setting due to anxiety."
