Abstract Summary
Objective: This study examines the impact of Ashwagandha (Withania somnifera) on cortisol levels and anxiety symptoms in individuals experiencing chronic stress.
Context: As an adaptogen, Ashwagandha is believed to help the body manage stress by lowering cortisol levels and reducing anxiety. This study aims to evaluate the efficacy of Ashwagandha in reducing these stress markers in chronically stressed adults.
Methods Used
Approach: A double-blind, randomized, placebo-controlled trial was conducted over 6 weeks. The study involved 80 participants aged 30-50 who reported chronic stress symptoms. The participants were divided into two groups: one group received 250 mg of Ashwagandha extract twice daily, while the control group received a placebo. Cortisol levels, anxiety symptoms, and sleep quality were assessed at baseline and post-treatment.
Data Collection: Primary outcome measures included cortisol levels (assessed via saliva tests), anxiety levels (measured using the Hamilton Anxiety Rating Scale), and sleep quality (evaluated through self-reported sleep diaries).
Researchers' Summary of Findings
Impact on Health: The results revealed a significant reduction in cortisol levels and anxiety symptoms in the Ashwagandha group compared to the placebo group. Cortisol levels in the Ashwagandha group decreased by an average of 30%, while the placebo group showed no significant change. Additionally, anxiety scores decreased by 40% in the Ashwagandha group compared to a 10% reduction in the placebo group. Improvements in sleep quality were also noted, with participants reporting better sleep patterns.
Health Implications: Ashwagandha supplementation appears to significantly lower cortisol levels and reduce anxiety in chronically stressed individuals. These findings suggest its potential use as a natural therapy for stress and anxiety management.
