Hygieia Brain

Hey Jacqui, Memory loss is not the first step toward Alzheimer’s. One of the earliest warning signs happens years before that, and that's losing your deep sleep. For a long time, most scientists assumed amyloid plaques were directly destroying sleep. But a brand new study points the finger somewhere else: your brain’s own immune cells, microglia. In an Alzheimer’s mouse model, researchers: left all the amyloid plaques in place temporarily removed overactive microglia Result: more than 2 extra hours of deep sleep restored per day, without touching a single plaque. I've just published a full YouTube video breaking down the study and what you can do to protect your brain against dementia: https://youtu.be/9OaPkm_XcWo It’s not just the plaque. It’s the chronic, overactive immune response in the brain that seems to be choking off deep sleep. That matters, because deep sleep is when your brain: runs the glymphatic system to wash out waste, including amyloid and tau lowers neuronal activity and amyloid release calms inflammation and stabilizes brain networks Large long‑term EEG studies now show that subtle changes in sleep architecture can predict dementia risk years before symptoms, even in people who appear “normal” in the day. So you have two levers: keep microglia from becoming chronically inflamed protect deep sleep as aggressively as possible You can’t take a lab drug and delete your microglia - doing so would be bad for brain health because the microglia in normal activity protect your brain. But you can build a lifestyle that keeps them calm, efficient, and less likely to sabotage your sleep. Here’s the sleep side of that equation. It's a vicious cycle - poor sleep promotes amyloid plaque accumulation, and that overactivates the microglia, which then damage the brain to reduce deep sleep. You start getting less deep sleep, and the cycle continues. Let me walk you through some of the most important things I've done to get my sleep scores to the 100s with 2-3 hours of deep sleep. My Evidence‑Based Sleep Optimization Protocol Sleep 7–8 hours every night Chronic short sleep accelerates biological aging, increases dementia risk, harms insulin sensitivity, and raises cardiovascular risk. Most adults do best with 7–8 hours. Keep a consistent schedule I’m usually in bed 9:30–10:00 PM, up 6:00–7:00 AM. Your circadian clock and immune system both run on this rhythm. The more consistent you are, the more microglia “know” when to repair vs when to stand down. Get morning sunlight 10–20 minutes outside within an hour of waking: anchors your circadian rhythm brings earlier melatonin release at night improves sleep quality and depth Block blue/green light 1–3 hours before bed Dim lights, use warmer colors, and if you’re on screens, use blue‑blocking glasses. When I started doing this, my deep sleep rose by ~15% on average. From my own data. Optimize your sleep environment cool room (about 17–20°C / 63–68°F) totally dark (blackout curtains or mask) quiet + fresh air / ventilation Finish eating 3–5 hours before bed Early dinner has been one of the biggest levers for my deep sleep. Late heavy meals keep your metabolism and immune system more active at night. Encourage nasal breathing If you snore or mouth‑breathe, experiment with nasal strips or gentle mouth taping (if appropriate). Even lean, fit people can have sleep apnea that fragments deep sleep. Reduce nighttime awakenings cut fluids 4–5 hours before bed manage stress earlier in the day eat enough total calories check for sleep apnea if you wake up repeatedly or unrefreshed Use targeted supplements (if needed) Magnesium (200–400 mg) for relaxation Glycine (3 g) to help lower core temperature and shorten sleep onset Low‑dose melatonin (0.3–1 mg) mainly for jet lag or circadian issues Train during the day Regular exercise improves deep sleep and circadian alignment. Just avoid all‑out sessions right before bed if they hype you up. Sleep isn't something you can just go do as you do with food. It's both a psychological and a physiological process that requires preparation and the correct state of mind.
