Normal blood pressure values are based on two measurements: systolic (the top number) and diastolic (the bottom number). Here’s the standard breakdown for adults:
Normal Blood Pressure
-
Systolic: 90–120 mmHg
-
Diastolic: 60–80 mmHg
So a typical “normal” reading would be around 120/80 mmHg.
Categories (for adults)
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| Hypertension Stage 1 | 130–139 | 80–89 |
| Hypertension Stage 2 | ≥140 | ≥90 |
| Hypertensive Crisis | >180 | >120 (seek immediate medical care) |
Key points:
-
Blood pressure can fluctuate throughout the day.
-
“Normal” may vary slightly based on age, health conditions, and guidelines from different health organizations.
-
Consistently high readings warrant evaluation by a healthcare professional.
If you want, I can also explain what factors can naturally raise or lower blood pressure so you know what’s considered healthy daily variation. Do you want me to do that?
