What is the Origin of Digital Sunset Routine?

This concept merges the natural phenomenon of a 'sunset,' signaling the start of darkness, with the clinical term 'routine,' which emphasizes consistent behavior for health outcomes. Its emergence is a direct response to the pervasive presence of digital technology and its documented disruptive effects on human circadian biology. The routine is a necessary strategy for managing environmental light input in a technology-saturated world.

What is the Mechanism of Digital Sunset Routine?

Exposure to the short-wavelength blue light emitted by digital screens suppresses the pineal gland's secretion of melatonin, the primary chronobiotic hormone that signals darkness to the body. By eliminating this inhibitory light cue, the routine allows for the unimpeded, timely release of melatonin, promoting somnolence. This restoration of the natural circadian signal optimizes the timing of sleep onset and subsequent deep sleep architecture.

Digital Sunset Routine

Meaning

A structured, pre-sleep behavioral practice that involves the systematic cessation of exposure to electronic screens and blue light-emitting devices for a defined period before the intended bedtime. This routine is implemented to support the natural, endogenous rise of melatonin and facilitate the transition into a state of physiological readiness for sleep. It represents a modern adaptation of traditional sleep hygiene principles tailored to the digital age.
