'Recent studies show poor sleeping habits cause both brain damage and brain shrinkage, and may even accelerate onset of Alzheimer’s disease.
Previous research published in the journal Science revealed that your brain removes toxic waste during sleep through what has been dubbed “the glymphatic system.”
This system becomes active during sleep, thereby allowing your brain to clear out toxins and harmful proteins.
Sleep is also necessary for maintaining metabolic homeostasis in your brain. Without sufficient sleep, your neurons will actually begin to deteriorate—and catching up on sleep during weekends will not prevent this damage.'
