Updated Blood Pressure Categories (AHA & WHO)
| Category | Systolic (mmHg) | Diastolic (mmHg) | Description |
|---|---|---|---|
 Normal | Less than 120 | and less than 80 | Ideal range |
 Elevated | 120–129 | and less than 80 | Early warning zone |
 High Blood Pressure (Stage 1) | 130–139 | or 80–89 | Mild hypertension |
 High Blood Pressure (Stage 2) | 140 or higher | or 90 or higher | Requires medical management |
 Hypertensive Crisis | Higher than 180 | and/or higher than 120 | Seek immediate medical attention |
If you experience symptoms like chest pain, severe headache, or shortness of breath with very high readings, call emergency services immediately.
What the World Health Organization (WHO) Says
What the World Health Organization (WHO) SaysThe WHO recognizes 120/80 mmHg as the ideal blood pressure for adults.
Above this level:
The risk of heart attack, stroke, kidney disease, and vision loss increases
Even slightly elevated pressures over time can damage blood vessels
“Maintaining healthy blood
is key to preventing cardiovascular disease — the world’s leading cause of death.” — World Health Organization
This is especially important after age 45, when arteries naturally stiffen and lifestyle factors can elevate blood pressure.
Does Normal Blood Pressure Change With Age?
Does Normal Blood Pressure Change With Age?While 120/80 mmHg is the ideal target at any age, average readings tend to rise slightly over time due to natural cardiovascular changes.
| Age Group | Average Systolic | Average Diastolic |
|---|---|---|
| 20–30 years | ~115 mmHg | ~70 mmHg |
| 40–50 years | ~125 mmHg | ~80 mmHg |
| 60+ years | ~135 mmHg | ~85 mmHg |
Remember: Average ≠ Healthy.
Older adults should still aim for below 130/80 mmHg, unless advised otherwise by their doctor. Recent studies show tighter control can reduce stroke and heart attack risk.
