Seasonal Affective Disorder (SAD) is commonly treated with bright light therapy. Virtual reality (VR) is an immersive computer-generated environment, which has been used to treat mental health difficulties, such as depression, social anxiety and stress. This study aims to compare the use of VR with bright light therapy in treating SAD. Participants will be randomly allocated to either the VR condition or the light box condition and instructed to use the respective device every day for 14 days.

A Placebo Controlled Study Evaluating The Effectivess Of Medication In Preventing Seasonal Affective Disorder
NCT01784705
Bright light therapy (BLT) has been found to be effective in treatment of seasonal affective disorder (SAD). The mechanism of action of conventional BLT in the treatment of SAD is under debate. Recently, transcranial bright light (TBL) via ear canals has been proved to modulate the neural networks of the human brain and improve cognitive performance in healthy subjects. Moreover, TBL has been found to alleviate symptoms of SAD in open trial. In this case the investigators will study the effect of transcranial bright light treatment via ear canals on depressive and anxiety symptoms in patients suffering from SAD in randomized controlled double-blind study design.
