This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
After a stroke, many patients struggle with depression, fatigue, and sleep problems that can slow their recovery. This trial is testing whether special lighting—artificial light designed to mimic the rhythm and spectrum of natural sunlight—can help improve these symptoms and support better brain healing during hospital rehabilitation. Researchers will measure the effects using questionnaires, brain scans, and blood tests.
Hospitals can disrupt the body's natural sleep-wake cycle because patients spend most of their time indoors under artificial lighting, which differs from natural sunlight. A previous study suggested this treatment might help, so researchers want to confirm whether this special lighting can truly improve depression, fatigue, and sleep in stroke patients and support their rehabilitation.

You will spend your hospital rehabilitation stay in a room equipped with special lighting that imitates natural sunlight patterns throughout the day and night. During your stay, you'll complete questionnaires about your mood, fatigue, and sleep; have brain scans (MRI); and provide blood samples to measure inflammation and sleep-related markers. The entire study takes place during your regular rehabilitation admission, so there are no extra hospital visits required.
