A recent, but small, clinical trial of dementia residents in a memory care facility used integrated ambient lighting that changed in intensity throughout the day to simulate natural light-dark cycles.
While the study published concluded that the lighting “may” help with depression, poor sleep quality, and agitation for those dealing with dementia, it ultimately concluded that further research was warranted.
However, the easier solution may be to try to make sure we get sufficient time in the natural light, rather than stuck inside with electric light all of the time – at any age and ability.
