Doctors have always checked blood pressure with people sitting down. They place a cuff around your upper arm, pump it up, and then measure how hard your heart is working.
This simple test is very common and helps doctors understand your risk for heart problems like strokes or heart attacks.
But new research suggests that checking blood pressure while you lie down flat could give doctors even more helpful information. This new idea has started conversations among doctors and scientists about whether we need to change how we measure blood pressure in the future.
Blood pressure is a very important sign of heart health. If it is too high, you have a greater chance of developing serious problems like a heart attack or stroke. Doctors usually look at two numbers: the top number (systolic pressure) shows how hard the heart pumps, and the bottom number (diastolic pressure) shows the pressure when the heart is resting.
There is a special test called 24-hour blood pressure monitoring, which gives the best results, but it is not comfortable or easy for most people. You have to wear a tight cuff all day and night. So, doctors usually just do the seated test in clinics.
Recently, a large study involving over 11,000 people tested blood pressure both while sitting and lying down. The researchers then put people into four groups: those with normal blood pressure in both positions; those with high blood pressure only while sitting; those with high blood pressure only while lying down; and those with high blood pressure in both positions.
The study found that people with normal readings in both positions had the lowest risk of heart problems. People with high blood pressure in both positions had the highest risk. But surprisingly, people who had high blood pressure only when lying down were nearly as likely to have heart issues as those with high readings in both positions.
This means some people may have hidden high blood pressure that only shows up when they lie down. If doctors only check while sitting, they might miss it. This could lead to a missed chance to prevent serious heart issues.
However, it’s too early to change how we test blood pressure. In the study, people were lying down for 20 minutes before their blood pressure was measured. That’s much longer than what usually happens at a clinic. So, more studies are needed before new rules can be made.
For now, the sitting blood pressure test will continue to be the standard. But this new research gives us a better idea of how our bodies work and how we might improve testing in the future.
Maybe in the years ahead, lying-down tests will help doctors find problems earlier and treat them better. It might even help doctors avoid giving strong treatments to people who don’t really need them.
This study shows that we should keep learning and testing new ways to take care of our hearts. As science moves forward, we might find better ways to protect our health.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more health information, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
