Light Exposure Management

Meaning

Light exposure management refers to the strategic, conscious control of the type, intensity, and timing of light exposure to positively influence the body’s neuroendocrine and circadian rhythm systems. This non-pharmacological intervention is critical for regulating the sleep-wake cycle, mood, cognitive function, and the diurnal secretion patterns of hormones like melatonin and cortisol. Effective management involves maximizing bright, blue-rich light exposure during the day and minimizing it in the evening.
