Have you ever visited the doctor and been told your blood pressure is high—only to find it’s completely normal when you check it at home?
If this sounds familiar, you might have something called white coat hypertension.
White coat hypertension happens when your blood pressure rises temporarily while you’re at a medical clinic or hospital.
It often happens because you feel nervous or stressed in that setting. The name comes from the white coats that doctors and nurses wear, which some people find intimidating.
This isn’t just your imagination or a one-time fluke. Scientists have studied this and found it’s a real and common condition. When you’re anxious or stressed, your body produces stress hormones like adrenaline.
These hormones make your heart beat faster and tighten your blood vessels, which pushes your blood pressure up. This is part of your body’s natural “fight or flight” response.
Studies show that up to 1 in 5 people may have white coat hypertension. It’s more common in older adults and in people who already feel nervous about going to the doctor. Usually, the blood pressure goes back to normal once the person leaves the clinic.
For a long time, doctors believed white coat hypertension wasn’t dangerous. But new research is starting to show that it might still cause problems, especially over time.
One large study published in the Journal of the American College of Cardiology found that people with white coat hypertension were more likely to develop true, long-term high blood pressure in the future.
Why does this happen? One reason may be that their blood vessels are more sensitive to stress. Over time, this sensitivity might cause lasting changes in the heart and arteries. Even if your blood pressure is only high at the doctor’s office, these repeated spikes could slowly wear down your heart and blood vessels.
The risk from white coat hypertension is still lower than from having high blood pressure all the time, but it’s not something to ignore. That’s why it’s important to find out if your high readings at the doctor are part of a bigger problem—or just a temporary response to stress.
To know for sure, your doctor may ask you to do what’s called ambulatory blood pressure monitoring. This means wearing a small device that checks your blood pressure at different times during the day, even while you sleep. It gives a clearer picture of what your blood pressure is really like in your everyday life.
Another option is to check your blood pressure at home. You can buy a home blood pressure monitor and take regular readings while you’re relaxed. If you do this, be sure to write down your results and show them to your doctor.
If you do have white coat hypertension, the good news is that you can do something about it. Many people find that lifestyle changes help a lot. Regular exercise, eating less salt, and eating more fruits and vegetables can lower your blood pressure.
Reducing stress also makes a big difference. Deep breathing, meditation, gentle stretching, and spending time in nature can all help calm your body and mind.
If your doctor thinks your risk is higher, they might suggest medication—even if your blood pressure is usually normal at home. This is more likely if you have other risk factors, like diabetes, heart disease, or a family history of high blood pressure.
There are also a few simple things you can try before or during a doctor’s appointment. Arrive a bit early and sit quietly for a few minutes. Try breathing slowly and deeply to calm yourself. Let the doctor or nurse know you feel nervous—they may be able to wait a bit before checking your blood pressure, or take a few readings to get a more accurate result.
The most important thing to remember is that white coat hypertension is real—and it matters. It’s not just about being nervous. It’s a condition that, if ignored, could turn into a more serious problem. But with a better understanding, smart habits, and support from your doctor, you can manage it and take good care of your heart for the long term.
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.
