What is the Origin of Systemic Repair Cycle?

This is a conceptual term synthesizing the body's systemic (whole-body) reliance on repair cycles (recurring processes of restoration). Its foundation is in chronobiology and gerontology, emphasizing the critical restorative role of rest and sleep architecture.

What is the Mechanism of Systemic Repair Cycle?

Deep non-REM sleep is crucial for the maximal pulsatile release of Growth Hormone, which stimulates cellular repair and protein synthesis throughout the body. Concurrently, the glymphatic system in the brain is highly active, clearing neurotoxic waste products accumulated during wakefulness. These processes are tightly linked to the activation of Sirtuins and AMPK pathways, which regulate DNA repair, cellular energy sensing, and overall cellular longevity.

Systemic Repair Cycle

Meaning

Systemic Repair Cycle is the integrated, biologically programmed sequence of cellular and molecular processes that occur predominantly during periods of deep rest and sleep to restore tissue integrity, clear metabolic waste, and repair accumulated DNA damage. This cycle is fundamentally governed by the pulsatile release of restorative hormones, such as Growth Hormone, and the activation of cellular clean-up mechanisms like autophagy. A compromised or abbreviated repair cycle accelerates biological aging and chronic disease development.
