What is brain cleanse?

The concept referred to as "brain cleanse" typically involves the brain's nightly process of clearing out metabolic waste during sleep. This process is part of the glymphatic system, where during the early stages of sleep, especially during the deep slow-wave sleep, the brain undergoes a significant cleaning mechanism. Misfolded proteins and other metabolic debris accumulated during the day are cleared out, which is crucial for maintaining brain health and function. This nightly cleansing is vital for the brain's recovery and preparation for the next day's cognitive activities 1.
