Trial Summary

What is the purpose of this trial?

Frailty is a multifactorial syndrome characterized by vulnerability to stressors that is intricately linked to cognitive impairment and mortality risk. Bright light therapy (BLT) reduces circadian disturbances by resynchronizing the hypothalamic biological clock via specific wavelengths of light. Human trials have demonstrated that BLT improves sleep quality and cognitive function in older adults. However, BLT has not been examined for use in older Veteran populations, particularly the impact on frailty. This randomized trial will assess the feasibility of employing BLT to study impacts on frailty, cognition, and sleep in older Veterans. Findings from this pilot will establish the power and effect size necessary for larger trials to support the use of BLT as readily available home-based treatment to improve healthspan of Veterans.

Eligibility Criteria

This trial is for older veterans who may be frail and have early-stage health issues. It's open to both men and women living in the community, but not those who are very overweight, without sleep problems, or with severe illnesses or cognitive impairments.
