Abstract Summary
Objective: This study evaluates the effects of Ashwagandha supplementation on improving sleep quality in individuals suffering from chronic insomnia.
Context: Ashwagandha (Withania somnifera) has been used in traditional Ayurvedic medicine to promote relaxation and improve sleep. Recent studies suggest that its adaptogenic properties may regulate cortisol and melatonin, influencing the sleep-wake cycle.
Methods Used
Approach: A randomized, double-blind, placebo-controlled trial was conducted over 8 weeks with 80 participants (ages 30-60) diagnosed with chronic insomnia. Participants were divided into two groups: one group received 600 mg of Ashwagandha root extract (300 mg twice daily) and the other received a placebo.
Data Collection: Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) at baseline, 4 weeks, and 8 weeks. Participants also completed sleep diaries to track subjective improvements, and serum melatonin levels were measured at baseline and at the end of the study.
Researchers' Summary of Findings
Impact on Health: By the 8th week, participants in the Ashwagandha group experienced a 25% improvement in PSQI scores compared to a 7% improvement in the placebo group. Additionally, serum melatonin levels were elevated by 18% in the Ashwagandha group, suggesting improved regulation of the sleep-wake cycle.
Health Implications: This research demonstrates that Ashwagandha supplementation may be an effective alternative for improving sleep quality in individuals with chronic insomnia, particularly those seeking natural remedies. The increase in melatonin suggests that Ashwagandha may play a role in promoting better sleep regulation. Further long-term studies are recommended to determine sustained benefits and dosage optimization.
