Patients often are nervous about what their blood pressure will be when it's measured at their doctor's office, and that anxiety causes their blood pressure to go up. It's known as “white coat hypertension,” and it's particularly common among elderly patients.
According to international recommendations 3 to 5 minutes of resting is needed before blood pressure measurement.
Stress can cause a steep rise in blood pressure. But when stress goes away, blood pressure returns to what it was before the stress. However, short spikes in blood pressure can cause heart attacks or strokes and may also damage blood vessels, the heart and the kidneys over time.
Anxiety doesn't cause long-term high blood pressure (hypertension). But episodes of anxiety can cause dramatic, temporary spikes in blood pressure.
High anxiety levels can lead to a spike in blood pressure, and getting a diagnosis of high blood pressure can lead to anxiety. However, some other medical conditions and medications can cause both high blood pressure and anxiety.
Usually, blood pressure starts to rise a few hours before a person wakes up. It continues to rise during the day, peaking in midday. Blood pressure typically drops in the late afternoon and evening. Blood pressure is usually lower at night while sleeping.
Your blood pressure comes down when you practice the relaxation response — even when simply breathing deeply for several minutes to calm your body. Regular practice of the relaxation response could help you reap more lasting benefits.
Moderate or severe headaches, anxiety, shortness of breath, nosebleeds, palpitations, or feeling of pulsations in the neck are some signs of high blood pressure. Often, these are late signs that high blood pressure has existed for some time, therefore annual checks are recommended for all adults.
Insomnia is linked to high blood pressure and heart disease. Over time, poor sleep can also lead to unhealthy habits that can hurt your heart, including higher stress levels, less motivation to be physically active, and unhealthy food choices.
Anxiety-induced increases in blood pressure are usually temporary and subside once the anxiety lessens. Regularly having high levels of anxiety, however, can cause damage to the heart, kidneys, and blood vessels in the same way that long-term hypertension can.
What causes high blood pressure? High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity. Certain health conditions, such as diabetes and having obesity, can also increase the risk for developing high blood pressure.
When stress and anxiety caused by a clinic or hospital visit lead to higher-than-normal blood pressure readings, the effect is known as white coat hypertension (WCH), or “white coat syndrome”, named for the coats doctors wear. WCH occurs in about one in five people.
Your blood pressure is considered high (stage 1) if it reads 130/80. Stage 2 high blood pressure is 140/90 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away. A reading this high is considered “hypertensive crisis.”
Still, you can make lifestyle changes to bring your blood pressure down. Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
A BP cuff that is too large will give falsely low readings, while an overly small cuff will provide readings that are falsely high.
Everyone's blood pressure rises and falls many times during the course of a single day, sometimes even within minutes. Many factors contribute to these changes, including physical activity, emotion, body position, diet (especially salt and alcohol intake), and sleep deprivation.
