Yoga May Lower Blood Pressure In People With Excess Weight, Analysis Shows

For adults carrying extra weight who know they should move more but dread workouts that leave their joints aching and lungs burning, a sweeping new analysis of 30 clinical trials offers a good reason to roll out a yoga mat. Researchers found that regular yoga practice led to a real drop in blood pressure among adults with overweight or obesity, a reduction large enough to matter for heart health.

Published in PLOS Global Public Health, the review is one of the largest to examine how yoga affects the health markers that shape a person’s risk of heart disease, stroke, and diabetes: blood pressure, cholesterol, blood sugar, and inflammation. Those risks climb sharply with excess body weight, and an estimated 5.02 million deaths worldwide in 2019 were attributed to a high body mass index. Yet people carrying extra pounds are among the least likely to adopt active lifestyles, often because exercise itself causes pain.

That reality is what makes yoga an attractive option. Unlike running or heavy weightlifting, yoga is a low-to-moderate intensity activity that combines physical postures, breathing techniques, and meditation. It carries minimal injury risk, costs little, and can be adapted to nearly any fitness level. The question this research team set out to answer was whether yoga actually moves the needle on the biological markers that drive obesity-related disease.

An International Team Searches for Yoga’s Effect on Blood Pressure

An international team searched seven scientific databases and two clinical trial registries for every eligible randomized trial that tested yoga against either no exercise or other forms of physical activity in adults with overweight or obesity. They defined “overweight” using World Health Organization guidelines: a body mass index of 25 or higher for most populations and 23 or higher for Asian populations, reflecting known differences in health risk at lower weights among Asian groups.

After sifting through more than 17,000 initial results, the team identified 30 trials involving 2,689 participants. Most were conducted in India (21 of them), with others taking place in Indonesia, Korea, the United States, Germany, and Australia. Only three studies specifically recruited people with overweight or obesity; in the vast majority, participants simply happened to have average body mass indexes in that range. Twenty-three trials, covering 2,313 participants, provided enough data for the researchers to pool their results mathematically.

Yoga Lowered Blood Pressure by a Clinically Meaningful Amount

Across 16 studies involving 962 participants, yoga lowered systolic blood pressure (the top number in a reading) by an average of 4.35 points and diastolic blood pressure (the bottom number) by about 2.06 points. At a population level, blood pressure changes of this size are considered meaningful for heart health, though this review did not test whether yoga reduced heart attacks or strokes.

Cholesterol results were modest. Yoga was linked to a small rise in “good” HDL cholesterol and reductions in triglycerides and VLDL, but it did not clearly lower “bad” LDL cholesterol or total cholesterol overall.

Blood sugar results were mixed. Yoga showed small benefits on measures of long-term blood sugar control and insulin resistance, but the effects on fasting blood sugar and after-meal blood sugar were not statistically meaningful.

On inflammation, yoga appeared to reduce several chronic inflammation markers, but researchers rated this evidence as uncertain because relatively few studies examined these outcomes and some had quality concerns.

Why Ethnicity and Yoga Dose Both Shaped the Results

One of the most notable patterns was the difference between Asian and non-Asian participants. Among Asian participants, yoga significantly lowered both blood pressure readings and improved several cholesterol markers. Among non-Asian participants, the effects on blood pressure did not reach statistical significance. Researchers suggested this gap could reflect biological differences across ethnic groups, cultural differences in how yoga is practiced, or simply the fact that far fewer studies have been conducted outside Asia.

How much yoga people did also mattered. In a narrower subgroup of well-designed studies testing yoga at least three sessions per week, each lasting at least 60 minutes, for at least 12 weeks, the benefits appeared larger among Asian participants, with cholesterol improvements following a similar pattern. The total weekly commitment of at least 180 minutes exceeds the standard 150-minute moderate-to-vigorous exercise recommendation, but because yoga is lower intensity, a longer duration is needed to burn comparable energy.

Where Yoga Fits and Where It Falls Short

Researchers were careful to note yoga is not a replacement for more vigorous approaches. Combined aerobic and resistance training has been reported as the most effective type for lowering blood pressure in people with excess body weight, producing drops of about 5.58 points for the top number and 4.70 points for the bottom. For blood sugar, moderate-to-vigorous endurance exercise and resistance training both outperformed yoga.

Still, the real-world appeal of yoga should not be dismissed. Pain is one of the most common barriers to physical activity for people carrying extra weight, and yoga’s gentleness makes longer commitments easier to sustain. The authors argued the findings support considering yoga as an add-on option in future clinical guidance for treating overweight or obese individuals. An exercise people will actually stick with is worth more than a perfect exercise that goes unused.
