When you visit your doctor, one of the first things they often do is check your blood pressure. Most people know that high blood pressure can be bad for your heart, but recent research suggests it might also affect how you feel and even your personality.
Blood pressure is measured with two numbers. The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure when your heart is resting between beats.
Many studies focus on systolic blood pressure, but now researchers are paying more attention to diastolic blood pressure. Surprisingly, this lower number might be linked to certain emotional traits.
One of these traits is called neuroticism. People with high levels of neuroticism tend to experience more negative emotions. They might feel more anxious, worried, sad, or easily frustrated than others.
For a long time, scientists wondered if there was a connection between blood pressure and these kinds of feelings. To find out, researchers turned to a special method called Mendelian randomization. This approach looks at people’s genes to understand how different health conditions might be linked.
Why use genetics? Well, our genes influence many aspects of our health, including our blood pressure. By studying the genes that control blood pressure, scientists can get a clearer picture of how it might affect our emotions without other factors getting in the way.
The researchers gathered DNA data from thousands of people. They looked for tiny differences in their genes that are known to affect blood pressure. By doing this, they could see if people with higher diastolic blood pressure also showed more signs of neuroticism.
Their findings were surprising. They found that people with higher diastolic blood pressure did indeed tend to have higher levels of neuroticism. This means that their feelings of worry, sadness, and stress were more intense.
Interestingly, the researchers did not find strong links between blood pressure and general anxiety or depression. This was unexpected because many people assume that high blood pressure is connected to all kinds of emotional stress. Instead, it seems like diastolic blood pressure is specifically tied to neurotic traits.
So, what does this mean for people with high blood pressure? It suggests that taking care of your heart might also help with your emotional well-being. If managing blood pressure can reduce feelings of neuroticism, it could lead to less stress and a more positive outlook.
This is important because people who are often anxious or easily upset tend to have higher blood pressure, which can make heart problems worse. It’s like a cycle—stress raises blood pressure, and high blood pressure may increase negative feelings.
Breaking this cycle could improve both mental and physical health. Doctors already know that exercise, healthy eating, and stress management can help lower blood pressure. Now, it seems these habits might also help people feel calmer and less stressed.
The study was led by Cai L and his team and published in the journal General Psychiatry. Their research opens up new possibilities for understanding how the heart and mind are connected. It also suggests that simple lifestyle changes could help people feel better emotionally, as well as physically.
In the end, this study is a reminder that our mental and physical health are deeply connected. Looking after your heart might do more than just protect you from heart attacks or strokes—it could help you feel happier and more at ease in your daily life.
