THE SLEEP THAT LITERALLY WASHES YOUR BRAIN!
You know sleep is important — but did you know your brain has a kind of “dishwasher mode”? Yes, it’s actually true.
Research over the past decade has shown that during deep sleep, the brain activates a cleaning system called the glymphatic system. It’s a type of lymphatic system in the brain that only works while you’re asleep — and its job is to flush out waste products that build up during the day. These include things like amyloid-beta, a protein linked to Alzheimer’s disease when it accumulates.
A groundbreaking study from 2013 (Nedergaard et al.) showed that this “brain-washing system” is up to 60% more effective during sleep than when we’re awake. When we don’t get enough sleep, this process is significantly impaired, which over time can affect memory, focus, and long-term brain health.
👉 In short: Sleep isn’t just about “resting” — it’s your brain’s cleaning shift. Don’t skip the night shift.
