Sorry, Yogi.
Recent research indicates that increasing heat in the warrior’s pose might not be as beneficial for cardiovascular health as previously believed.
But fans of mindful movement need not despair entirely. The study highlighted three types of training that seem to better support heart health, two of which also focus on breathing, balance, and mental clarity.
The findings stem from a collaboration between researchers at the University of Sharjah in the UAE and the Manipal Academy of Higher Education in India. They analyzed ten studies comparing yoga to other exercise forms in inactive adults.
The goal was to assess how these workouts impact blood vessel function, essentially how effectively your blood vessels transport blood and nutrients throughout the body.
Sitting too much can disrupt this flow, increasing the risk of high blood pressure, arterial blockages, and blood clots.
Dr. Lina David, a medical imaging expert and one of the study’s authors, likened blood vessels to “a flexible garden hose.” When they become stiff, the likelihood of heart attacks and strokes increases.
The research unveiled mixed results regarding yoga. In one study, some middle-aged participants experienced improved blood flow after eight weeks of heated yoga, with a decrease in artery stiffness, while younger adults saw no changes.
Researchers propose that this age disparity impacts vascular health outcomes. Older individuals typically have stiffer arteries, allowing for more noticeable improvement. Gentle yoga may not alter younger people’s more supple arteries.
However, even for older participants, results were inconsistent. Some studies noted better vascular function, while others did not.
Specifically, practicing in a 105-degree room did not yield any significant mental benefits compared to regular temperature classes, like those in Bikram Yoga.
When comparing other mind-body exercises, such as Tai Chi and reformer Pilates—both emphasizing fluid movements and deep breathing—these methods displayed more reliable vascular benefits.
Significantly, high-intensity interval training (HIIT) demonstrated even more pronounced effects, effectively reducing arterial stiffness, especially in colder conditions.
In contrast, short bursts of activity—like brief walks or taking stairs—provided minimal advantages.
“Even simple routines can bolster artery resilience,” Dr. David noted, explaining that “blood vessels have memories” and every workout helps counteract the damage from prolonged sitting.
Nonetheless, she emphasized the importance of consistent movement for maintaining vascular health, rather than just occasional bouts of activity.
While yoga retains numerous health benefits, the findings suggest integrating more vigorous activities into exercise routines for those looking to enhance vascular health.
Dr. David emphasized the need for public health initiatives to promote movement as a crucial element for health, likening inactivity to a contemporary threat to arterial well-being.
She concluded that combining different exercise forms, including yoga, could make heart health more accessible and culturally relevant.
