Light therapy guides

The physics, clinical context, and buying decisions behind brighter mornings—written to separate useful evidence from wellness marketing.

Editorial standard

Health claims need a higher bar.

Every health-related claim in these guides is checked against a published study, clinical guideline, or recognized medical source. Anecdotes are not presented as evidence, and a lamp is never framed as a substitute for care.

Our role is to make the research and specifications legible—then show where the evidence ends and a conversation with a healthcare professional should begin.
