Taking blood pressure while lying down could result in more accurate readings, new research from the American Heart Association finds. Experts explain findings.

Why Position Matters While Taking Blood Pressure Reading? A lot depends on the positioning of your body and your arms when it comes to getting accurate blood pressure readings.
