The Glymphatic System: How Your Brain Cleans Itself During Sleep
Discover the recently identified waste clearance system that only activates during deep sleep, and why it matters for long-term brain health.
01
Sleep is the foundation of human performance. During sleep, the brain consolidates memories, clears metabolic waste through the glymphatic system, and restores neural circuits. Research shows that even modest sleep deprivation impairs cognitive function, emotional regulation, and immune response. The sleep economy is projected to reach $585 billion by 2032, reflecting a growing awareness that rest is not passive — it is the most powerful performance-enhancing tool available.
Science Snapshot
Adults who sleep fewer than 7 hours per night show a 12% increased risk of premature mortality. Deep sleep (N3) is when growth hormone peaks, tissue repair occurs, and the brain's waste clearance system activates.
