%X <strong>Purpose: </strong>We aimed to investigate the effects of installing false windows next to hospital beds without windows on the amount of light received by patients and their sleep quality. <strong>Methods:</strong> The study included patients admitted to the Department of Neurology at our hospital between September 2020 and August 2021. An Actigraph device was fitted to patients¡¯ wrist and their beds to measure the amount of light received and sleep quality. Patients were divided into three groups: bed with a window, aisle bed with a false window, and aisle bed without a window. Mean sleep efficiency (%), mean steps (per day), and the amount of light (lux) received by the patients and beds were measured. <strong>Results:</strong> Valid data were obtained for 48 participants (median age, 66.5 years). There were 23 patients in beds with a window, 13 patients in aisle beds without a false window, and 12 in aisle beds with a false window. No statistically significant differences were found in terms of mean sleep efficiency, number of steps taken, and the amount of light received by the patients (<em>P</em> &gt; 0.05); however, difference in the mean amount of light received by the beds at the location of the bed was statistically significant (<em>P</em> &lt; 0.001). <strong>Conclusion: </strong>The amount of light that the patient receives is not necessarily affected by the location of the bed or the presence of a false window.
