Ever heard of the brain’s own cleaning crew? It’s called the glymphatic system, and it gets to work while you sleep, flushing out toxins linked to dementia. But if your sleep is all over the place—thanks, insomnia or sleep apnoea—this system might not do its job, letting toxic gunk build up. Scientists are still figuring out exactly how it works in humans, but one thing’s clear: quality sleep could be your brain’s best friend for the long haul. #Health #BodyHealth #SleepScience
