How Stress Is Linked to High Blood Pressure

Daily stressors can increase BP in the moment, as well as contribute to habits that can feed long-term hypertension

Feeling stressed? If so, you’re hardly alone, given that stress has been called the health epidemic of the 21st century. But have you ever wondered what all this stress means for your blood pressure?

The answer, it turns out, is more complex than you might think. Let’s take a closer look with preventive cardiologist Luke Laffin, MD.

Does stress raise blood pressure?

Stressful moments can totally send your blood pressure (BP) skyrocketing. You feel it deep in your core, too, as your heart thumps harder and your nerves jangle with a fight-or-flight response.

“If we’re in a stressful situation, the normal physiologic response is to increase blood pressure,” explains Dr. Laffin. “But your body can handle these sorts of acute changes in blood pressure pretty well.”

And once the immediate stressor is gone, your BP should return to its typical level.

Of course, not all stress clocks out like it’s a shift worker. Chronic stress tends to linger — and that can contribute to a long list of physical symptoms, including high blood pressure (hypertension).

The connection between stress and hypertension

Researchers don’t know as much about the direct effects of long-term stress on blood pressure. But they do know that stress can impact lifestyle habits and increase your risk of heart disease and other chronic health issues.

“Stress itself doesn’t necessarily cause sustained elevations in blood pressure,” says Dr. Laffin. “But it often has an impact on lifestyle factors, which can absolutely contribute to long-term elevations in blood pressure.”

When you’re chronically stressed, you can fall into habits that can lead to higher blood pressure and increase your risk of heart disease. These include:

• Sleeping too little, too much or poorly
• Not exercising as much
• Make unhealthy food choices
• Smoking
• Drinking alcohol

It can be difficult to see when acute stress transitions to chronic stress. But seemingly “temporary” stressors that last for weeks can turn into chronic stressors that need to be addressed for the sake of your heart health.

“What we’re really worried about is chronically elevated blood pressure,” states Dr. Laffin.

Can lowering stress lower your BP?

Finding ways to better manage your stress can help keep your blood pressure from rising and staying at elevated levels, suggests Dr. Laffin. He suggests:

• Focusing on fitness: “Working out regularly is a great way to feel better, decrease stress levels and better adapt to difficult situations,” says Dr. Laffin. The positive effects of exercise on heart health are also important for your blood pressure.
• Catching ZZZs: The quantity and quality of your sleep matter for your BP. “For stable blood pressure, you need to get about six to eight hours of uninterrupted sleep at night,” he advises.
• Minimizing stressors: To reduce stress, you need to address its causes. Of course, that can be easier said than done when stressors involve your job or family. In these cases, additional steps, like therapy, may help you find coping strategies.
• Adopting a heart-healthy diet: Foods high in sodium and saturated fats can increase blood pressure even before you add stress to the mix. Embracing a Mediterranean-style diet and eating more antioxidant-rich foods can help keep your BP down.
• Calming techniques: Various forms of meditation can help you calm your mind and tamp down stress. There’s evidence that mindfulness-based stress reduction can lower BP within a few months.

Medications like beta-blockers may also be an option if stress seems to be driving blood pressure into danger zones. Antihypertensives can help bring down high blood pressure, too.

“But managing stress-related hypertension usually comes down to lifestyle,” clarifies Dr. Laffin. “Diet, exercise, sleep — those are all factors that play a big role in keeping your heart healthy.”
