Keeping blood pressure under control is one of the most important ways to protect your health as you get older. Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps.
It is measured using two numbers. The top number, called systolic blood pressure, shows the pressure when the heart beats. The bottom number, called diastolic blood pressure, shows the pressure when the heart relaxes between beats. Together, these numbers help doctors understand how hard the heart is working.
High blood pressure, also known as hypertension, often develops without obvious symptoms. Many people feel perfectly well even when their blood pressure is dangerously high. For this reason, it is sometimes called the “silent killer.”
Over time, high blood pressure can damage blood vessels throughout the body, increasing the risk of heart attacks, strokes, heart failure, kidney disease, vision loss, and memory problems.
On the other hand, blood pressure that is too low can also cause problems, especially in older adults. If blood pressure drops too much, people may feel dizzy, weak, or lightheaded. They may faint or fall, which can lead to broken bones or other serious injuries. Finding the right balance is especially important after the age of 60.
For many years, doctors generally recommended keeping systolic blood pressure below 140 millimeters of mercury (mmHg) for older adults. This target was believed to reduce the risk of heart disease while avoiding side effects from too much medication. However, researchers continued to ask whether lowering blood pressure even further could provide greater protection.
One of the most important studies to examine this question was the Systolic Blood Pressure Intervention Trial, better known as the SPRINT study.
This large clinical trial included thousands of adults who had a high risk of heart disease but did not have diabetes. The research compared two treatment strategies. One group aimed for a systolic blood pressure below 120 mmHg, while the other group aimed for below 140 mmHg.
The results attracted worldwide attention. People in the intensive treatment group, whose blood pressure was lowered to below 120 mmHg, experienced fewer heart attacks, strokes, heart failure events, and deaths related to cardiovascular disease. These findings suggested that lowering blood pressure more aggressively could offer extra protection for many people.
However, the study also showed that intensive treatment was not without risks. People whose blood pressure was lowered to very low levels were more likely to experience side effects such as dizziness, fainting, low blood pressure, kidney problems, and changes in body salt levels.
Older adults may be particularly sensitive to these complications because they are more likely to fall and may already have other health conditions.
As a result, many experts now recommend a more personalized approach instead of using one target for everyone. For many healthy adults over 60, aiming for a systolic blood pressure below 130 mmHg, while generally avoiding levels below 120 mmHg, appears to provide a good balance between reducing heart disease risk and limiting unwanted side effects.
The best target can still vary from person to person. Someone with diabetes, chronic kidney disease, frailty, or several other medical conditions may need a different blood pressure goal.
Doctors also consider a person’s age, overall health, medicines, and whether they experience symptoms such as dizziness when standing up. These factors help create an individual treatment plan rather than relying on a single number.
Lifestyle habits remain a key part of blood pressure management. Eating a healthy diet that is low in salt, exercising regularly, maintaining a healthy weight, avoiding smoking, limiting alcohol, managing stress, and getting enough sleep can all help lower blood pressure naturally.
When lifestyle changes are not enough, medications may also be needed to keep blood pressure in a healthy range.
Regular blood pressure checks are equally important because high blood pressure often causes no warning signs. Home blood pressure monitors and routine medical visits allow doctors to see whether treatment is working and make adjustments if necessary.
The message from modern research is clear. There is no perfect blood pressure target that fits every older adult. Instead, the goal should be chosen carefully for each individual, balancing the benefits of lowering blood pressure with the possible risks of treatment.
Working closely with a healthcare provider and following a personalized treatment plan offers the best chance of staying healthy, active, and independent well into later life.
