Research indicates that yoga activates the parasympathetic nervous system, promoting relaxation and better sleep. Poses like Balasana (Child Pose), Supta Matsyendrasana (Supine Twist), Viparita Karani (Legs Up the Wall), Marjaryasana-Bitilasana (Cat-Cow), and Savasana (Corpse Pose) help reduce cortisol levels and regulate sleep cycles, supporting effective insomnia management.
