High blood pressure rarely causes symptoms, which is why it's often called a silent condition. Knowing your numbers is one of the simplest things you can do for your long-term heart health.
The two numbers explained
A reading such as 120/80 mmHg has two parts. The top number, systolic pressure, is the force in your arteries when your heart beats. The bottom number, diastolic pressure, is the pressure between beats, when your heart is resting.
What counts as normal?
- Healthy: generally below 120/80 mmHg.
- Elevated: a top number between 120 and 129.
- High: consistently 130/80 mmHg or above, depending on the guideline your doctor uses.
- Very high: 180/120 mmHg or above needs urgent medical attention.
Habits that make a real difference
Reducing salt, moving most days, limiting alcohol, sleeping well and managing stress can each lower blood pressure. Together, the effect can be similar to taking a medication. If lifestyle changes aren't enough, your doctor may suggest treatment, which is safe and effective for most people.
