Introduction
Blood pressure is a vital sign that reflects the force exerted by circulating blood on the walls of blood vessels. It’s an essential aspect of cardiovascular health, influencing the risk of various conditions such as heart disease, stroke, and kidney failure. In this guide, we’ll explore what blood pressure is, how it’s measured, and what the numbers mean for your health.
What is Blood Pressure?
Blood pressure is the pressure of circulating blood against the walls of the arteries, the major blood vessels in your body. It is typically measured in millimeters of mercury (mmHg) and recorded with two numbers:
- Systolic Pressure: The first (higher) number measures the pressure in your arteries when your heart beats.
- Diastolic Pressure: The second (lower) number measures the pressure in your arteries when your heart rests between beats.
Understanding Blood Pressure Readings
Normal blood pressure is considered to be around 120/80 mmHg. However, readings can vary depending on various factors such as age, activity level, and overall health. Here’s a breakdown of what different blood pressure ranges mean:
- Normal: Less than 120/80 mmHg
- Elevated: 120-129/<80 mmHg
- Hypertension Stage 1: 130-139/80-89 mmHg
- Hypertension Stage 2: 140 or higher/90 or higher mmHg
- Hypertensive Crisis: Higher than 180/higher than 120 mmHg (requires immediate medical attention)
