Yoga, an ancient Indian mind‑body practice, has transformed the global health landscape over the past two decades. The Indian government announced National Yoga Day in 2015, while the World Health Organization (WHO) also recognized yoga's role in stress management and the prevention of non‑communicable diseases. This article presents the history of yoga, scientific evidence, and its current socio‑economic context, enabling readers to understand it as a comprehensive health strategy.

Historical Background
The roots of yoga are found in ancient Vedic texts, but its modern form evolved from Patanjali’s Yoga Sutras (circa 200 BCE). Patanjali divided yoga into eight limbs (Ashtanga), comprising Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana, and Samadhi. In the 20th century, Swami Vivekananda and the Patanjali Yoga Institute introduced yoga to Western countries, accelerating its popularity on an international scale.

Scientific Evidence and Health Benefits
Studies published in major medical journals have demonstrated numerous benefits of yoga. A meta‑analysis (2021) found that regular yoga practice reduces systolic blood pressure by an average of 5–7 mmHg, improves cholesterol levels, and lowers the risk of cardiovascular disease. Psychological research shows that yoga reduces the stress hormone cortisol, leading to significant decreases in symptoms of depression and anxiety. In respiratory science, pranayama techniques increase lung capacity and improve oxygen saturation in patients with respiratory conditions.

Integration of Yoga into National Policies
Prime Minister Narendra Modi launched the “Atma Yoga” initiative in 2015, aiming to make yoga mandatory in schools, colleges, and workplaces. Many state governments are incorporating yoga into their health‑safety programs, such as Karnataka’s “Yoga Abhyasan” plan and Maharashtra’s “Yoga Wellness” program. Abroad, the United Nations recognized International Yoga Day in 2014, establishing yoga as both a cultural heritage and a public health tool.

Economic Impact and Future Direction
The yoga industry generated approximately US $120 billion in global revenue in 2022, including online classes, certified instructors, and yoga‑based equipment. During the COVID‑19 pandemic, demand for online yoga classes grew by over 300 %, opening new possibilities for digital platforms. In the future, the Indian government plans to incorporate yoga into the National Health Insurance Scheme by 2025, ensuring that economically disadvantaged groups can also benefit from this practice.

Conclusion
Yoga not only provides physical flexibility and strength but also brings mental clarity and spiritual balance. The convergence of scientific evidence, governmental support, and economic investment has made it a reliable health strategy. As more people adopt yoga, its benefits are likely to expand further.
