A new clinical trial from Stanford University has proven that a 7-day wellness retreat can significantly reduce stress hormone levels and enhance cognitive clarity.


Published in Nature Mind & Health, the study involved 72 participants who attended a structured retreat with yoga, meditation, digital detox, and plant-based meals.

Key findings:

  • Cortisol levels dropped by 32% on average
  • EEG scans showed increased alpha brain wave activity (linked to creativity and relaxation)
  • Participants reported better memory, clarity, and emotional regulation after just one week Lead researcher Dr. L. Gomez commented: “This is the most measurable evidence yet that immersive retreats alter brain function and biochemical balance.” The study also included a control group on a regular vacation—with no significant change in stress or brain metrics. Retreats are not just relaxing—they're neurological interventions.
