Brief summary

Dr. Gina Poe discusses the intricacies of sleep, emphasizing the importance of regular bedtime for growth hormone release, the roles of sleep phases in learning, memory, and emotional processing, and how specific sleep patterns can aid trauma therapy and addiction recovery.

Highlights

💤

The significance of consistent bedtime routines for optimal growth hormone release and overall health is underscored, with a focus on the first few hours of sleep.
