Dawn Simulator Reviews (Wake-Up Lights)

The Science of Dawn Simulator Lamps

A 2015 study published in the Journal of Affective Disorders concluded that dawn simulator lamps are equally effective at managing Seasonal Affective Disorder (SAD) as bright light therapy. The study found dawn simulator lights, which mimic the gradual increase of sunlight in the morning, to be 42.2% effective, and bright light therapy, which employs a 10,000 lux light upon waking, to be 43.8% effective at curing winter depression (Seasonal Affective Disorder). Though the authors noted a personal preference towards bright light therapy among more severely depressed patients, the study suggests that the differences in treatment outcomes were small enough to allow a patient’s personal preference and comfort to be the deciding factor, concluding: “both types of therapy were recognized by American Psychiatric Association as the first-line treatment for winter depression.”
