Sleep's Active Role in Brain Health

Contrary to the perception of sleep as a passive state, it plays an active role in maintaining brain health. During sleep, the brain is far from dormant; it engages in a vital cleansing process. Brainwaves, often misconceived as mere indicators of sleep stages, are instrumental in this process. They facilitate the movement of cerebrospinal fluid throughout the brain, effectively flushing out metabolic waste and toxins accumulated during waking hours. This nightly cleansing is not just a routine maintenance task; it's a critical function for cognitive health and longevity.
