Admission to a single room with potential exposure to natural light via windows was not associated with reduced delirium burden, as compared to admission to a single room without windows. However, natural light exposure was associated with a reduced risk of agitation episodes and hallucinations.

A total of 195 patients were included.

The incidence of delirium was similar in the LIGHT group and the DARK group.

Compared with the DARK group, patients from the LIGHT group were less likely to be intervened with antipsychotics for agitation episodes and had less frequent hallucinations.

Consecutive patients admitted to a single room with (LIGHT group) or without (DARK group) exposure to natural light via windows were evaluated for delirium.
