1. Decoding Blood Pressure: Systolic vs. Diastolic
Blood pressure readings consist of two numbers, each providing vital information about your heart’s function:
- Systolic Pressure: Represents the pressure in your arteries when your heart contracts to pump blood.
- Diastolic Pressure: Represents the pressure in your arteries when your heart is at rest between heartbeats.
Ideally, blood pressure should be less than 120/80 mm Hg. Elevated blood pressure is between 120-129 systolic and less than 80 diastolic. Hypertension, or high blood pressure, is diagnosed when readings consistently reach 130/80 mm Hg or higher.
