The Critical Link Between Poor Sleep and Alzheimer’s Disease
Emerging research highlights a powerful connection between poor sleep and the development of Alzheimer’s disease. One of the key culprits is beta-amyloid—a toxic protein that can accumulate in the brain and is strongly linked to the progression of Alzheimer’s.
During deep non-REM sleep, the brain activates the glymphatic system, a waste clearance pathway that acts like a nightly rinse cycle for the brain. This system flushes out harmful metabolic waste, including beta-amyloid. When sleep is disrupted or shortened, especially deep sleep, this cleansing process is impaired, allowing beta-amyloid to build up over time.
Interestingly, a lack of restorative deep sleep can create a vicious cycle: the more beta-amyloid builds up, the harder it becomes to achieve deep sleep, accelerating cognitive decline. This underscores the critical role of quality sleep not just in daily function, but in long-term brain health and Alzheimer’s prevention.
Getting consistent, high-quality sleep may be one of the most powerful tools we have for protecting the brain as we age. Would you like a graphic to go with this post?
#WhyWeSleep

As promised, here's the sleep quality summary for 5 days (I'd have a sixth but forgot to set it last night)
Not great I assume. Gonna see if I can improve it with things like tea at night
