Sleep Epigenetics

Meaning

Sleep Epigenetics is the study of the complex, bidirectional relationship between sleep—its duration, quality, and timing—and the epigenetic landscape, specifically focusing on modifications like DNA methylation and histone acetylation. This field investigates how sleep acts as a powerful environmental modulator of gene expression, profoundly impacting hormonal balance, metabolic health, and cellular repair processes across the human system. Optimal sleep is essential for maintaining a healthy, resilient epigenome and preventing the acceleration of age-related decline.
