Blue Light Management Sleep

Meaning

This clinical strategy involves the deliberate control of short-wavelength, high-energy visible light exposure, particularly in the hours preceding sleep, to support optimal circadian rhythm function. Effective management aims to prevent the light-induced suppression of endogenous melatonin production, the key sleep-regulating hormone. It is a foundational element in chronobiology-informed sleep hygiene protocols designed to enhance restorative sleep stages. The practice promotes alignment between the internal biological clock and the external environment.
