Blood pressure naturally changes with age, but there are widely accepted “normal” ranges for adults. Blood pressure is measured in millimeters of mercury (mmHg) and recorded as systolic/diastolic (top/bottom number).
Here’s a breakdown by age:
🧍♂️ Adults (18+ Years)
| Age Group | Normal Blood Pressure (mmHg) | Notes |
|---|---|---|
| 18–39 | ~120/80 | Healthy adults; lifestyle affects this range |
| 40–59 | ~130/85 | Slight increase with age is normal |
| 60+ | ~140/90 | Some guidelines allow slightly higher systolic if no other conditions |
Key points:
-
Systolic = pressure when heart beats
-
Diastolic = pressure when heart rests between beats
-
Optimal: <120/80 mmHg at any age if possible
👶 Children & Teens
Blood pressure norms vary by age, sex, and height percentile. General reference:
| Age | Typical BP (mmHg) |
|---|---|
| 1–3 years | 95/65 |
| 4–5 years | 100/65 |
| 6–9 years | 105/70 |
| 10–12 years | 110/70 |
| 13–15 years | 115/75 |
| 16–17 years | 120/75 |
⚠️ When to Be Concerned
-
Hypertension: ≥130/80 mmHg (for adults, per ACC/AHA 2017)
-
Hypotension: <90/60 mmHg (if causing symptoms like dizziness, fainting)
💡 Tips for Accurate Measurement
-
Rest for 5 minutes before measuring
-
Sit with feet flat and back supported
-
Use a properly sized cuff
-
Avoid caffeine, smoking, or exercise 30 minutes prior
🫀 Lifestyle Tips to Maintain Healthy BP
-
Eat a balanced diet (DASH diet: fruits, veggies, low sodium)
-
Exercise 30 minutes most days
-
Maintain a healthy weight
-
Limit alcohol and avoid smoking
-
Manage stress
If you want, I can also make a chart of ideal blood pressure by decade with color-coded risk levels, which makes it super easy to see if your readings are normal, elevated, or high.
