Bright Light Therapy for Post-COVID-19 Fatigue

This randomized placebo‐controlled trial aims to evaluate the efficacy of BLT in reducing fatigue symptoms after COVID‐19 infection. The second aim of the study is to explore the effects of BLT on insomnia, depression and anxiety symptoms. Method: Each eligible participant will be randomized to either i) bright light therapy (BLT) or ii) dim red light (placebo) treatment for 30‐minutes daily at their habitual wake time for a total of two weeks. Participants will be evaluated at baseline, 2nd (end of treatment), and 4th week (post‐treatment 2‐week) for fatigue and other symptoms.
