Blood pressure naturally varies with age, activity, and health, but there are generally accepted “normal” ranges. Blood pressure is measured as systolic/diastolic (mmHg).
Normal Blood Pressure by Age
| Age Group | Normal Systolic (mmHg) | Normal Diastolic (mmHg) |
|---|---|---|
| Children (1–5) | 90–110 | 55–75 |
| Children (6–13) | 95–115 | 60–80 |
| Teenagers (14–19) | 105–120 | 65–80 |
| Adults (20–39) | 110–125 | 70–80 |
| Adults (40–59) | 115–130 | 75–85 |
| Adults 60+ | 120–140 | 80–90 |
Key Points
- Systolic = pressure when the heart beats.
- Diastolic = pressure when the heart rests between beats.
- Slightly higher readings are common in older adults.
- Consistently high readings (>130/80 for adults) may indicate hypertension.
- Consistently low readings (<90/60) may indicate hypotension, especially if symptomatic.
💡 Tips for Accurate Measurement
- Sit quietly for 5 minutes before measuring.
- Use the correct cuff size.
- Avoid caffeine, smoking, or exercise 30 minutes prior.
- Take multiple readings at different times for accuracy.
If you want, I can make a simple chart with color codes for normal, elevated, and high blood pressure by age, so it’s easy to read at a glance.
