Insomnia is a widespread sleep disorder that affects overall health and daily functioning. This case study examines the impact of a structured yoga program on a 60-year-old man with a five-year history of insomnia characterized by difficulty initiating sleep, frequent awakenings, and irritability. The intervention consisted of a one-hour daily yoga routine for 90 days, including Pawanamuktasana Series I, Surya Namaskar, AUM chanting, and relaxation practices. Sleep quality was assessed using the Insomnia Severity Index (ISI) before and after the intervention.

The patient’s ISI score improved from 18 (moderate insomnia) to 12 (subthreshold insomnia), reflecting notable enhancement in sleep quality, reduced anxiety, better emotional regulation, and improved morning freshness. These findings align with existing evidence showing that yoga supports autonomic balance and reduces psychological stress. This case suggests that yoga may serve as an effective, non-pharmacological option for managing chronic insomnia, warranting further research in larger populations.
