Abstract Summary
Objective: This study aims to evaluate the effects of Ashwagandha on sleep latency (time taken to fall asleep) and total sleep duration in adults with anxiety-induced sleep disorders.
Context: Ashwagandha is recognized for its stress-reducing properties, which may help individuals with anxiety-induced sleep difficulties. By reducing stress and anxiety levels, it may help to shorten sleep latency and extend overall sleep duration, leading to better restorative sleep.
Methods Used
Approach: A 6-week, randomized, placebo-controlled trial was conducted with 120 adults (ages 35-50) who reported anxiety-related sleep problems. Participants were randomly assigned to receive either 250 mg of Ashwagandha extract twice daily or a placebo.
Data Collection: Sleep latency and sleep duration were monitored using actigraphy and self-reported sleep diaries at baseline, 3 weeks, and 6 weeks. Anxiety levels were also measured using the Hamilton Anxiety Rating Scale (HAM-A).
Researchers' Summary of Findings
Impact on Health: After 6 weeks, the Ashwagandha group demonstrated a 20% reduction in sleep latency and a 15% increase in total sleep duration. The HAM-A scores in the Ashwagandha group also decreased by 18%, compared to a 5% reduction in the placebo group. Participants reported feeling more rested upon waking and experiencing fewer anxiety-induced nighttime disruptions.
Health Implications: The findings suggest that Ashwagandha can effectively reduce sleep latency and improve sleep duration, particularly in individuals with anxiety-induced sleep problems. Its adaptogenic effects in lowering stress and anxiety make it a promising natural supplement for managing sleep disorders. Additional long-term studies are recommended to further explore its sleep-enhancing potential.
