Blood pressure measures the force of blood pushing against your artery walls. High blood pressure, or hypertension, is one of the most common risk factors for heart disease and stroke, and many people have it without knowing.
What the numbers mean
A reading has two numbers: systolic (when your heart beats) over diastolic (when it rests), measured in mmHg.
| Category | Typical reading |
|---|---|
| Normal | Below 120/80 |
| Elevated | 120–129 / below 80 |
| High | 130/80 or higher (some guidelines use 140/90) |
Thresholds differ between guidelines. Your doctor will interpret your readings based on repeated measurements.
Habits that can help lower blood pressure
- Reduce salt: WHO recommends under 5 g of salt, about 2 g of sodium, per day.
- Eat more fruit, vegetables and whole grains.
- Be active most days.
- Maintain a healthy weight.
- Limit alcohol and avoid smoking.
- Manage stress and sleep well.
Measuring at home
- Sit quietly for five minutes, feet flat, arm supported at heart level.
- Avoid caffeine, exercise and smoking for 30 minutes before.
- Take two readings a minute apart and note them down.
If your readings are consistently high, see your doctor. Never stop or change blood pressure medication on your own.
