MIT study links sleep deprivation to brain's cleanup causing attention lapses

New research from MIT reveals that when sleep-deprived individuals experience attention lapses, their brains trigger waves of cerebrospinal fluid to clear waste, mimicking a sleep-like process. This compensation disrupts focus temporarily but may help maintain brain health. The findings, published in Nature Neuroscience, highlight the brain's adaptive response to missed rest.

The authors describe this as the first study to show a same‑day association between diet and objectively measured sleep.
