Casey Means on Artificial Light and Circadian Disruption: warns against

Dr. Casey Means criticizes modern artificial-light habits for wrecking sleep-wake cycles and contributing to metabolic dysfunction. On The Model Health Show (#791), Means warned about circadian disruption, and published summaries of Good Energy note she warns against screens and phones in the bedroom.

Means’s stated reasoning is that light is a primary signal for the body’s clock genes and circadian rhythm, and that evening screen exposure and bedroom light pollution undermine the sleep quality her framework treats as a metabolic pillar. This position pairs with her positive recommendation of morning sunlight and light hygiene — avoid artificial light at night, seek natural light by day.
