What this trial studies

This clinical trial aims to evaluate the effects of photobiomodulation on insomnia in elderly participants aged 60 and above who have experienced sleep issues for at least three months. The study will recruit 60 participants and assess their sleep parameters and biological rhythms using questionnaires and actigraphy. Participants will be exposed to different types of light therapy, including bright light, near-infrared light, and a combination of both, to determine the most effective intervention. Data analysis will involve various statistical methods to compare outcomes before and after treatment, while also monitoring for any adverse events.

Who should consider this trial

Good fit: Ideal candidates for this study are older adults aged 60 and above who have been suffering from insomnia for at least three months.

Not a fit: Patients with movement disorders, certain eye diseases, or those currently taking sedative-hypnotic drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive treatment option for insomnia in older adults, potentially improving their sleep quality and overall well-being.

How similar studies have performed: While the specific approach of using photobiomodulation for insomnia in the elderly is relatively novel, light therapy has shown promise in other studies for improving sleep quality.
