Episode Description
We follow the science that links deep sleep, circadian timing, and brain energy to how fast we age. We connect glymphatic waste clearance, the SCN master clock, melatonin biology, and meal timing to Alzheimer’s risk, memory function, and longevity.
• the glymphatic system as a deep sleep waste-clearance mechanism for amyloid beta and tau
• how cerebrospinal fluid moves through perivascular spaces and drains to lymph nodes
• why aquaporin-4 channels act like valves and how aging makes the plumbing inefficient
• 40 hertz gamma entrainment as a non-invasive attempt to boost clearance plus limits and unknowns
• why pharmacological “forcing” of clearance risks systemic side effects and is not a simple fix
• the SCN as the master circadian clock that uses light to time cortisol, sex hormones, and thyroid output
• circadian syndrome as a pathway to mitochondrial dysfunction and oxidative stress in neurons
• the hamster SCN transplant studies that restore rhythms and extend lifespan
• melatonin as a whole-body timing signal that influences epigenetics via SIRT1 and supports healthy autophagy
• why sleep deprivation triggers synaptic scaling problems and a chemical lockdown of memory circuits
• clock-aligned eating and time-restricted feeding as a way to resynchronize peripheral clocks
• the BMAL1 paradox showing caloric restriction can fail or harm when clock machinery is broken
