Discovered only in the last decade, the glymphatic system is the brain’s unique waste-removal pathway. Unlike other organs, the brain lacks traditional lymphatic vessels, so this system uses cerebrospinal fluid to flush out toxins during sleep, including proteins linked to Alzheimer’s disease. Poor sleep may impair this process, leading to cognitive decline over time. Researchers are now exploring ways to enhance glymphatic function through sleep optimization, hydration, and even novel therapies. Understanding this system could revolutionize treatments for neurodegenerative disorders and highlight why deep, restorative sleep is vital for long-term brain health and memory preservation.
