Seasonal Affective Disorder Phototherapy

Meaning

Seasonal Affective Disorder Phototherapy is a clinically established, non-pharmacological treatment involving daily exposure to a high-intensity, full-spectrum light source to alleviate the depressive symptoms associated with Seasonal Affective Disorder (SAD). This intervention is specifically designed to correct the hypothesized neuroendocrine imbalance, particularly the disruption of melatonin and serotonin regulation, that occurs in susceptible individuals during the low-light months of autumn and winter. It is a targeted method of manipulating light input to stabilize mood and circadian function.
