Sleep Cycle Epigenetics

Meaning

Sleep Cycle Epigenetics describes the dynamic, sleep-stage-dependent changes in gene expression regulation that occur through various epigenetic mechanisms, such as DNA methylation and histone modification, during the nocturnal rest period. This essential interplay ensures the timely activation and repression of genes critical for deep metabolic repair, widespread neuroplasticity, and the consolidation of complex memories. The quality, duration, and architecture of sleep profoundly impact the fidelity and accuracy of these essential genetic modifications.
