Light Therapy as Treatment for Fatigue in Multiple Sclerosis

This prospective study will randomize 1:1 people living with multiple sclerosis-associated fatigue to one of two spectra of light therapy. Each participant will be asked to use the light box twice daily at home or at the workplace at preset hours during the day for a total of four weeks. Participants will be asked to record their fatigue on standard measurement scales before, during, and after the use of the light therapy box. The investigators anticipate a reduction in self-reported fatigue following the use of the light box therapy of a particular spectrum of light among people living with multiple sclerosis.
