An interventional study of Active luminette and Placebo luminette in Insomnia Chronic, Sleep Disorder and Circadian Rhythm Disorders, sponsored by University Hospital, Strasbourg, France. Completed at 3 sites in France. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2025-03-12.
Sponsored by University Hospital, Strasbourg, France · Not applicable, Interventional, and Treatment
Insomnia affects 15 to 20% of the general French adult population and increases with age. General practitioners (GPs) are the first confronted to sleep disorders, especially insomnia.
Cognitive-behavioral therapies (CBT) have proven effective, but their implementation in everyday practice is limited, and alternative treatments are still needed.
Light not only has a great influence on the sleep-wake cycle and alertness, but also on mood and cognitive functions.
The administration time of light condition will be calculated for each individual in a modality that has no impact on the circadian phase.
Study will be conduct on an outpatient basis in general practice
