Unlock Your Brain with Better Glymphatic Clearance | HOMe Podcast #028

In this episode of the Health Optimization Medicine Podcast, Dr. Scott Sherr, Dr. Allen Bookatz, and Jodi Duval explore the glymphatic system and the role sleep plays in clearing metabolic waste from the brain.

Getting eight hours of sleep does not necessarily mean getting eight hours of effective brain clearance. The team looks at how the autonomic nervous system, norepinephrine, cerebrospinal fluid and interstitial fluid exchange, aquaporin-4 channels, circadian timing, body temperature, gut barrier integrity, and even anxiety around wearable sleep scores may influence the conditions needed for healthy glymphatic flow.

The discussion also introduces a practical HOMeHOPe glymphatic optimization protocol focused on creating the chronobiological, bioenergetic, and environmental conditions that support natural overnight brain clearance.

Join us as we delve into:

• How the Glymphatic System Works: How cerebrospinal fluid moves through perivascular spaces, exchanges with interstitial fluid, and helps remove metabolic waste including beta-amyloid, tau, and cellular metabolites.

• Circadian Biology, NAMPT and NAD+: How CLOCK and BMAL1 influence NAMPT and the NAD+ salvage pathway, and why disrupted circadian rhythms can affect cellular maintenance.

• The Autonomic Nervous System: How elevated sympathetic tone and nighttime norepinephrine can interfere with the conditions required for glymphatic flow.

• Circadian Biology and Brain Health: Why light timing, cortisol rhythms, and autonomic balance matter for creating the right conditions for overnight clearance.

• The HOMeHOPe Glymphatic Optimization Protocol: Practical strategies involving morning light, evening light reduction, bedroom temperature, sleeping position, autonomic safety, and gut barrier support.

• The Role of Sleep Hygiene: Why the environment and signals surrounding sleep may matter just as much as the number of hours spent in bed.

• The Skeptical Position: The team examines the conventional neurology argument that slow-wave sleep architecture, aging, and aquaporin-4 changes may limit how much glymphatic function can be influenced through lifestyle.

• Precision vs. Generic Sleep Advice: Why HOMeHOPe emphasizes measurement, metabolomics, circadian markers, and individualized guidance rather than simply telling someone to "get more sleep."

This episode is for you if:

• You get enough hours of sleep but still wake up with brain fog or fatigue.

• You want to understand how the glymphatic system supports brain health during sleep.

• You are interested in the relationship between sleep hygiene, circadian biology, and brain clearance.

• You use a wearable to track sleep and want to understand the potential downside of becoming overly focused on sleep scores.

• You are interested in practical, non-pharmaceutical approaches to supporting healthy brain function and sleep.
