1. What is a Normal Blood Pressure Reading and Why Does It Matter?
A normal blood pressure reading is typically considered to be less than 120/80 mmHg. The top number, systolic pressure, measures the pressure in your arteries when your heart beats. The bottom number, diastolic pressure, measures the pressure in your arteries when your heart rests between beats. Maintaining a normal blood pressure reading is crucial because it reduces the risk of heart disease, stroke, kidney disease, and other serious health issues.
Why it matters: High blood pressure, or hypertension, often has no symptoms, making it a silent killer. Regular monitoring and maintaining healthy blood pressure levels are essential for preventing long-term health complications.
2. What Are the Different Blood Pressure Categories?
Blood pressure is categorized into different ranges, each indicating a specific health status. According to guidelines, these categories include:
- 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
Understanding these categories helps in identifying whether your blood pressure is within a healthy range or requires intervention.
3. How Do I Check My Blood Pressure Accurately?
Checking your blood pressure accurately involves using the right equipment and following a consistent procedure. Here’s how to do it:
