Hormonal Photoregulation

Meaning

Hormonal Photoregulation is the scientifically recognized process by which specific wavelengths and intensities of light, primarily through non-visual pathways, directly influence the synthesis, secretion, and metabolism of hormones within the human body. This process extends far beyond the well-known melatonin suppression by blue light, encompassing the regulation of thyroid hormones, sex steroids, and cortisol. It highlights the profound and direct connection between the environmental light spectrum and the intricate operations of the endocrine system. Clinically, understanding this photoregulation is paramount for designing chronobiologically-aligned wellness protocols.
