Sleep-wake problems like insomnia and excessive daytime sleepiness are common after traumatic brain injury (TBI). Researchers are studying whether morning bright light therapy (MBLT) can improve sleep quality in Veterans, including those with TBI. This study aims to understand the effects of MBLT on sleep in Veterans recruited from the VA Portland Health Care System. Participants will either receive 60 minutes of morning bright light therapy at 10,000 lux within 90 minutes of waking each day for 4 weeks or will not receive this intervention. The study randomly assigns Veterans to either the therapy group or a control group without intervention. Data collection includes baseline sleep questionnaires and 7 days of actigraphy, followed by continuous actigraphy during therapy, and post-therapy questionnaires. Follow-up questionnaires are done 3 months after therapy ends. Throughout the study, participants will wear actigraphy devices to monitor sleep patterns and complete questionnaires on sleep quality. The main outcome measured is the change in the Insomnia Severity Index (ISI) from baseline to after 4 weeks of therapy and again 2 months later. This study lasts several months, including initial baseline assessments, 4 weeks of therapy, and follow-up evaluations to assess lasting effects.
