The Yoga- Heart Connection

Exercise that revs up your heart rate isn’t the only kind of physical

activity that can help prevent or manage heart disease.

The calming exercise of yoga is good for the heart, too. “A large

number of studies show that yoga benefits many aspects of

cardiovascular health,” says Hugh Calkins, MD, Director of the Cardiac

Arrhythmia Service at Johns Hopkins. “There’s been a major shift in

the last five years or so in the number of cardiologists and other

professionals recognizing that  these benefits are real.”

Yoga is a mind-body activity that involves moving through a series of

body poses and breathing exercises that can improve strength, flexibility, balance and relaxation. Dozens of different formats, or practices, such as hatha, anusara, ashtanga and many others, emphasize different focuses, such as toning, strength training or meditation.

 Yoga as a Stress Outlet 

One of yoga’s clearest benefits to the heart is its ability to relax the body and mind. Emotional stress can cause a cascade of physical effects, including the release of hormones like cortisol and adrenaline, which narrow your arteries and increase blood pressure. The deep breathing and mental focus of yoga can offset this stress.

Worry and depression commonly follow a cardiac event, such as a heart attack, bypass surgery or diagnosis of heart disease. As part of an overall treatment plan, yoga can help you manage this stress.

Yoga as Heart Booster

Beyond off-loading stress, practicing yoga may help lower blood pressure, blood cholesterol and blood glucose levels, as well as heart rate, making it a useful lifestyle intervention. One study has shown that blood measurements and waist circumference—a marker for heart disease—improved in middle-aged adults with metabolic syndrome who practiced yoga for three months.

Another study has shown that slow-paced yoga classes twice a week reduced the frequency of atrial fibrillation episodes in patients with that condition. In another report, patients with heart failure who went through an eight-week yoga program showed improvement in exercise capacity and quality of life. They also had lower blood levels of markers for inflammation, which contributes to heart disease.

Yoga as Exercise

Yoga can also improve flexibility, muscle strength and balance. Because it’s not a form of aerobic exercise that raises the heart rate, however, you shouldn’t count the time you spend doing it as part of your recommended weekly total for moderate to vigorous physical activity.

Yoga as Smoking Cessation Aid

Some research indicates yoga might be a useful tool in helping smokers quit. Smoking is one of the biggest risk factors for heart disease.
