The proposed study aims to establish the feasibility of light therapy for postpartum depression delivered via Re-Timer, demonstrate its preliminary efficacy, and illuminate relationships between circadian shifts and mood changes using a novel, home-based circadian biomarker assessment paradigm (salivary dim light melatonin onset; DLMO).
