The Strange Way Your Brain Shrinks at Night to Clean Itself

When your head hits the pillow, your brain gets to work. Cells shrink, fluid flows in, and waste from the day is washed away. This “night shift” keeps your memory sharp and your thinking clear. But when you cut sleep short, that cleaning cycle shuts down, and harmful buildup begins.

In this video, we look at what scientists discovered about the brain’s cleaning system, how modern habits like screens, stress, and late nights interfere with it, and simple steps you can take to give your brain the rest it needs.

Sleep is not wasted time. It’s maintenance for your mind and it may protect your memory for years to come.
