How Ashwagandha Improves Sleep

The Connection: Sleep disorders affect millions worldwide, with stress and anxiety being primary contributors to poor sleep quality. Ashwagandha's adaptogenic properties target these underlying causes.

🧠 Mechanism of Action

Primary Pathways

  • • Cortisol Regulation: Reduces elevated cortisol levels that disrupt circadian rhythm
  • • GABA Enhancement: May increase GABA activity, promoting relaxation
  • • Stress Reduction: Lower stress naturally improves sleep quality
  • • Nervous System Calming: Prepares the body for rest

Sleep Cycle Benefits

  • 🌙 Faster Sleep Onset: Fall asleep more quickly
  • 💤 Deeper Sleep: Improved sleep quality and efficiency
  • ⏰ Longer Duration: Increased total sleep time
  • ☀️ Better Mornings: Enhanced alertness upon waking

Clinical Evidence
