Normal blood pressure is defined as a systolic pressure of less than 120 mmHg and a diastolic pressure of less than 80 mmHg.
Understanding Blood Pressure Readings
Blood pressure is measured with two numbers:
- Systolic pressure (the top number) indicates the pressure in your arteries when your heart beats.
- Diastolic pressure (the bottom number) indicates the pressure in your arteries when your heart rests between beats.
Both numbers are important for determining if your blood pressure is within a healthy range.
Blood Pressure Categories
Healthcare professionals categorize blood pressure readings to help assess cardiovascular health and identify potential risks. Here's a breakdown of the categories:
| Blood Pressure Category | Systolic Pressure (mm Hg) | AND/OR | Diastolic Pressure (mm Hg) |
|---|---|---|---|
| Normal | Less than 120 | AND | Less than 80 |
| Elevated | 120 to 129 | AND | Less than 80 |
| High Blood Pressure Stage 1 | 130 to 139 | OR | 80 to 89 |
Maintaining blood pressure within the normal range is crucial for long-term health, as it reduces the risk of serious health conditions. For more detailed information, you can consult resources like the National Heart, Lung, and Blood Institute.
