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.
