What is the Origin of Solar Dawn Protocol?

This term is a clinical naming convention for the practical application of chronobiology principles, specifically leveraging the phase-advancing effect of morning light. It formalizes an ancient, biologically innate behavior—rising with the sun—into a modern, actionable health strategy. The protocol is rooted in the understanding of the retinohypothalamic tract.

What is the Mechanism of Solar Dawn Protocol?

Upon retinal registration of the high-intensity, full-spectrum light, the intrinsically photosensitive retinal ganglion cells (ipRGCs) signal the Suprachiasmatic Nucleus (SCN) that the biological day has begun. This signal immediately suppresses any residual nocturnal melatonin and initiates the hypothalamic-pituitary-adrenal (HPA) axis cascade, leading to the necessary cortisol awakening response. This robust signal anchors the internal clock, improving Sleep Wake Cycle Fidelity.

Solar Dawn Protocol

Meaning

The Solar Dawn Protocol is a structured, clinical recommendation involving the deliberate, timed exposure of the eyes to natural, unfiltered solar light immediately upon waking, ideally within the first 30 minutes. This protocol is utilized to powerfully and accurately set the master circadian clock, ensuring optimal timing for the diurnal release of cortisol and the subsequent suppression of nocturnal melatonin. It is a foundational, non-pharmacological intervention for regulating the sleep-wake cycle.
