Lighting control for Cluster Headache primarily works by modulating melatonin production and circadian rhythm disruptions through precise light wavelength and intensity manipulation. By targeting photoreceptive pathways in the hypothalamus, particularly the suprachiasmatic nucleus, controlled lighting interventions can help normalize neurological signaling and reduce the frequency and intensity of cluster headache episodes. The mechanism involves suppressing or stimulating specific photoreceptors to reset neurological and endocrine patterns associated with headache pathogenesis.
