Keeping blood pressure in a healthy range is one of the best ways for older adults to protect their health.
Blood pressure is the force created when blood moves through the arteries. If it stays too high for a long time, it puts extra strain on the heart and blood vessels, increasing the risk of heart attack, stroke, heart failure, and kidney disease.
If it becomes too low, it may cause dizziness, fainting, and serious falls, which can be especially dangerous later in life.
For many years, doctors usually aimed to keep the top blood pressure number, called systolic blood pressure, below 140 mmHg for most older adults. This advice was based on the knowledge available at the time and helped reduce many health problems.
As more research became available, however, scientists began to wonder whether lowering blood pressure even further could provide extra protection.
One of the most important studies to examine this question was the Systolic Blood Pressure Intervention Trial, better known as the SPRINT trial. The findings were published in The New England Journal of Medicine.
Researchers followed thousands of adults aged 50 years and older who had a high risk of heart disease but did not have diabetes. Participants were placed into two groups, with one group aiming for a systolic blood pressure below 140 mmHg and the other aiming for below 120 mmHg.
The results attracted worldwide attention. People in the lower-target group experienced fewer heart attacks, fewer strokes, and fewer deaths related to heart and blood vessel disease. The study showed that carefully lowering blood pressure could offer important health benefits for many people who were at higher risk.
Even so, the researchers also found that lower is not always better for everyone. Some participants developed side effects such as dizziness, low blood pressure, or kidney problems. Older adults who become unsteady may also have a greater chance of falling, which can lead to broken bones and a loss of independence.
Because of these findings, doctors now recommend a more personal approach instead of giving every older adult the same blood pressure goal.
For many healthy adults over 60, aiming for a systolic blood pressure below 130 mmHg, while avoiding levels below about 120 mmHg unless closely supervised, offers a good balance between lowering heart risks and reducing unwanted side effects.
The right target still depends on the individual. People with diabetes, chronic kidney disease, or several other medical conditions may need different goals. Those who have had repeated falls, feel dizzy when standing, or take many medicines may also need a treatment plan that is adjusted to suit their needs.
Regular blood pressure checks remain very important because blood pressure naturally changes over time. Home blood pressure monitors, healthy eating, regular physical activity, maintaining a healthy weight, reducing salt intake, limiting alcohol, avoiding smoking, and taking prescribed medicines correctly can all help keep blood pressure under control. Regular visits with a doctor or nurse also make it easier to adjust treatment if needed.
The main goal is not to reach the lowest number possible but to find a safe range that protects both the heart and the brain while allowing people to feel well and stay active.
A personalised treatment plan gives older adults the best chance of enjoying better health, greater independence, and a higher quality of life as they age.
