Blue Light Spectrum Avoidance

Meaning

Blue Light Spectrum Avoidance is a behavioral and environmental strategy focused on minimizing exposure to light wavelengths between approximately 450 and 495 nanometers, particularly in the hours leading up to the natural sleep onset. This clinical practice is specifically employed to prevent the disruption of the body’s natural circadian rhythm and to ensure optimal melatonin secretion. This targeted reduction in short-wavelength light exposure supports neuroendocrine health and improves sleep architecture.
