6 powerful yoga poses

πŸ§˜β€β™€οΈ What Is Yoga? Meaning, Importance, and Health Value

Yoga is an ancient mind-body practice that originated in India more than 5,000 years ago. The word β€œyoga” comes from the Sanskrit root β€œYuj,” meaning to uniteβ€”the union of body, mind, and breath. In modern life, yoga is widely practiced as a holistic wellness system that combines physical postures (asanas), breathing techniques (pranayama), and mindfulness.

Unlike high-impact workouts, yoga focuses on balance, flexibility, strength, and mental calmness. Scientific research now confirms that regular yoga practice helps reduce stress, improve posture, support heart health, enhance muscle tone, and promote emotional well-being. Yoga is suitable for people of all ages when practiced correctly and under proper guidance.
