6 powerful yoga poses
π§ββοΈ 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 βyogaβ comes from the Sanskrit root βYuj,β meaning to uniteβthe 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.
