NOTE

The Impact of Sleep on Brain Connectivity

Sleep plays a crucial role in connecting the medial prefrontal cortex to the amygdala in the brain. With lack of sleep, this connection is severed, leading to heightened emotional reactivity and decreased regulatory control over emotions, making individuals more emotionally reactive and less rational.

Episode notes

This is episode 5 of our 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley and the host of The Matt Walker Podcast. In this episode, we explain the connection between sleep and mood, emotional regulation and mental well-being.

We explain the role of rapid eye movement (REM) sleep in processing emotions and emotional memories and why sleep deprivation causes agitation, impulsivity and emotional reactivity.

We also discuss why sleep disruption is a hallmark feature of PTSD, anxiety, depression, suicidality, and other psychiatric conditions.

We explain protocols for improving REM sleep and other sleep phases in order to harness the therapeutic power of quality sleep to feel calmer and emotionally restored.

This episode describes various actionable tools to improve sleep for those struggling with mental health or mood and those wanting to bolster their overall state and well-being.

The next episode in this special series explores dreams, including lucid dreaming, nightmares and dream interpretation.
