@dralexwibberley: Sleep isn’t wasted time. It’s when your brain does essential housekeeping. At night, a clearance system kicks in, flushing out toxins and waste — including amyloid, the protein linked to Alzheimer’s disease. If you cut your sleep short to try and achieve more, that clearance doesn’t happen properly. Over time, waste builds up and damages brain cells. It’s like never taking the bins out — eventually the house becomes unliveable. Research shows poor sleepers are at higher risk of dementia later in life. And fixing it isn’t complicated: go to bed at the same time, aim for 7–9 hours, keep your room dark and cool, and avoid caffeine late in the day. It might sound simple, but as a doctor I see what happens when people neglect it — their brains age faster. Think of sleep as your nightly detox, the cheapest and most powerful way to keep your mind sharp for decades. Save this to remind yourself tonight. #Sleep #BrainHealth #Longevity #Wellbeing
