Cellular Regeneration Window

Meaning

The Cellular Regeneration Window refers to a specific, finite period, typically occurring during the deep stages of nocturnal sleep, when the body’s repair, restoration, and anabolic processes are maximally upregulated. This is the optimal time for tissue remodeling, cellular debris clearance via autophagy, and the peak pulsatile secretion of key anabolic hormones, notably Growth Hormone (GH) and Prolactin. Maximizing the depth and duration of this window is a critical objective in clinical longevity and hormonal optimization protocols.
