I n this latest AMA episode, Matt and Dr. Eti Ben Simon explore the complex web connecting sleep to our health and daily lives. They investigate the gut-brain axis, discussing how sleep deprivation alters the microbiome and whether probiotics can restore balance. The conversation also addresses the heavy toll of bereavement, examining the bidirectional link between acute grief and insomnia while offering evidence-based strategies to manage sleep during times of loss. The discussion shifts to creativity, revealing how REM sleep acts as "informational alchemy" to fuel innovation for artists and scientists alike. Matt and Eti share practical tips for harnessing sleep for breakthroughs, including Edison's famous napping technique.
