Light Therapy in End Stage Kidney Disease

This study tests whether light therapy (exposure to a bright light device) can reduce fatigue in patients with end-stage kidney disease who are on regular hemodialysis (kidney dialysis three times per week). Fatigue is one of the most common and disabling symptoms in dialysis patients, and light therapy may help by resetting the body clock and improving sleep. **You may be eligible if...** - You are 18 years or older - You have end-stage kidney disease and have been receiving hemodialysis three times per week for at least one month - You experience significant fatigue (score above 9 on the Fatigue Severity Scale) - You have a home refrigerator (needed to store saliva samples for the study) **You may NOT be eligible if...** - You have eye conditions such as cataracts, glaucoma, or macular degeneration - You have a condition that makes you sensitive to light, such as photosensitive epilepsy - You are currently hospitalized or acutely ill Talk to your doctor to see if this trial is right for you.
