What is the Origin of Sleep Deprivation Genetics?

This is an interdisciplinary term combining sleep medicine, behavioral science, and genomics. The clinical observation that individuals respond differently to sleep restriction led to the investigation of the underlying genetic factors. Key genes involved are often those regulating circadian rhythms and neurotransmitter signaling.

What is the Mechanism of Sleep Deprivation Genetics?

Genetic variants in clock genes, such as PER3, can affect the homeostatic drive for sleep and the resulting cognitive deficits following deprivation. Other polymorphisms influence the stress response system, impacting the surge of cortisol and inflammatory markers during sleep loss. These genetic differences modulate the downstream effects on glucose metabolism, immune function, and neurobehavioral performance.

Sleep Deprivation Genetics

Meaning

Sleep Deprivation Genetics is the study of how inherited genetic variations influence an individual’s susceptibility to the negative cognitive, metabolic, and physiological consequences of insufficient sleep. Certain genetic polymorphisms dictate the resilience or vulnerability of the neuroendocrine system to the stress of sleep loss. This field provides the basis for understanding the bio-individual response to chronic sleep debt.
