Understanding Your Blood Pressure Numbers

Blood pressure is one of the most important vital signs, yet many people don't fully understand what their numbers mean. Let's break it down.

Systolic vs. Diastolic: The Two Numbers

The top number (systolic) measures pressure when your heart beats; the bottom number (diastolic) measures pressure between beats. Both matter, but systolic pressure is particularly important as a risk factor for cardiovascular disease.

What's a Healthy Range?

Normal blood pressure is below 120/80 mmHg. Elevated readings (120-129/less than 80) warrant lifestyle changes, while readings of 130/80 or higher may require medical attention.

Lifestyle Factors That Affect Blood Pressure

Sodium intake, physical activity, stress, sleep quality, alcohol consumption, and weight all influence blood pressure. Small lifestyle changes can yield significant improvements.

Regular monitoring is key—hypertension is often called the "silent killer" because it rarely causes symptoms until serious damage occurs.
