The Impact of Yoga on Heart Health

The Impact of Yoga on Heart Health

James Re

Many people think of yoga mainly as an activity that promotes flexibility and balance. But this ancient tradition also includes breathing exercises, relaxation, and meditation. Together, these practices can lead to measurable improvements in factors connected with cardiovascular health, such as lower blood pressure, better sleep, and less artery-damaging inflammation.

Better overall fitness

Active forms of yoga, such as power or Vinyasa yoga, are listed as examples of moderate-intensity exercise in the federal exercise guidelines. But the less-vigorous forms of yoga (as well as the active forms) boost muscle strength, flexibility, and balance. These features, which are often overlooked in other forms of exercise, are vital for overall physical fitness and well-being. Yoga also encourages deep, slow breathing, which helps lower blood pressure by an average of five points after a few months of regular practice, research suggests.

Sustained self-regulation

The relaxing, meditative aspect of yoga can build up your emotional resilience, helping you to stay calmer during times of stress. Stress — an unavoidable part of our daily lives — activates the body's fight-or-flight response. This triggers a rise in heart rate, blood pressure, and the release of stress hormones, all of which are hard on your cardiovascular system. Yoga helps activate the opposite effect, known as the rest-and-digest response. Over time, a regular yoga practice cultivates this "relaxation response," enabling you to be less reactive to stress and intense emotions. A single 90-minute session of yoga can lower levels of the stress hormone cortisol.

Greater mind-body awareness

In a 2012 survey from the National Center for Complementary and Integrative Health, more than 80% of yoga enthusiasts said the practice decreased their stress. Nearly two-thirds reported that yoga motivated them to exercise more regularly. And four in 10 said they were inspired to eat healthier. These changes may reflect the heightened mind-body awareness that yoga practitioners experience. You're more aware of the positive feelings you enjoy when you eat healthy foods and exercise. You're also more likely to notice the negative effects of eating junk food and sitting on a couch all day. Making healthy lifestyle changes is perhaps the most important thing you can do to prevent heart disease.

Transformation over time?

After years of doing yoga, some people find that the practice transforms their lives to an even greater degree. They have a different perspective on the meaning and purpose of their life, and their goals become less materialistic and more spiritual and charitable. While the relevance to heart disease may be tenuous, some research has found that people with a higher sense of purpose in life are less likely to have a heart attack, stroke, or related cardiovascular problem compared with people who have a lower sense of purpose.

Moreover, there's good evidence dating back to 1990 that a lifestyle that includes yoga as one of its four key components (along with a low-fat vegetarian diet, moderate exercise, and the maintenance of loving, supportive relationships) can actually shrink blockages in arteries, without the use of medication.

Getting started with yoga

If you're new to yoga, seek out a beginner or "gentle" class, especially if you're over 65 or have any medical conditions. To reap the greatest reward, find a class that features all four pillars of yoga: postures, breathing practices, deep relaxation, and meditation. In addition to dedicated yoga studios, many health clubs and community or senior centers now offer classes. You might need some persistence to find a teacher and style of yoga that resonates for you, but it will be worth it.
