1. What Is Considered Normal Blood Pressure?
Normal blood pressure (BP) is generally defined as a reading less than 120/80 mmHg (millimeters of mercury). This measurement includes two numbers: systolic (the pressure when the heart beats) and diastolic (the pressure when the heart is at rest). Maintaining BP within this range is important for reducing the risk of heart disease, stroke, and other health problems.
To further clarify, let’s break down the components of normal BP:
- Systolic BP: This measures the pressure in your arteries when your heart muscle contracts or beats. A normal systolic reading is typically below 120 mmHg.
- Diastolic BP: This measures the pressure in your arteries when your heart muscle is resting between beats. A normal diastolic reading is typically below 80 mmHg.
According to the American Heart Association, normal blood pressure falls within these ranges:
- Normal: Less than 120/80 mmHg
- Elevated: Systolic between 120-129 mmHg and diastolic less than 80 mmHg
- Hypertension Stage 1: Systolic between 130-139 mmHg or diastolic between 80-89 mmHg
- Hypertension Stage 2: Systolic at least 140 mmHg or diastolic at least 90 mmHg
- Hypertensive Crisis: Systolic over 180 mmHg and/or diastolic over 120 mmHg
It’s crucial to regularly monitor your blood pressure and consult with a healthcare professional if your readings consistently fall outside the normal range. Understanding your blood pressure numbers is the first step in maintaining good cardiovascular health.
