PSALM 127:2 In vain you rise early, and stay uo to late, toiling for food to eat--
For he grants SLEEP to those he loves.

Long-term sleep deprivation leads to an overabundance of immune cells in the brain, particularly glial cells like microglia and astrocytes. Astrocytes, responsible for clearing brain connections, begin dissolving synapses and debris, offering short-term protection but potentially causing long-term damage. Excessive microglial activation, linked to neurodegenerative diseases like Alzheimer's, raises concern, as prolonged sleep deprivation impairs memory consolidation, reduces cognitive abilities, and increases vulnerability to neurological disorders. Sleep also supports immune response, hormone balance, and emotional regulation, emphasizing its critical role in brain health and the potential risks of chronic sleep loss.
