Do you sleep for 8 hours but still wake up feeling tired or foggy?
Science reveals that after age 60, it’s not about how long you sleep—it’s about how deeply your brain can clean itself.
In this video, we explore the neuroscience of the “Glymphatic System”—your brain’s nightly cleaning crew—and why it often stops working efficiently as we age.
We dive deep into:
– Why 8 hours isn’t enough anymore
– The “Brain Shrinking” phenomenon explained (Science, not fear)
– What is the Glymphatic System?
– The connection between deep sleep and memory
– 4 Science-backed steps to restore deep sleep tonight
This isn’t just about feeling rested. It’s about protecting your cognitive longevity.
We go beyond basic sleep hygiene to understand the biological shifts happening in your body right now.
