As we get older, sleep quality suffers, and poor sleep can lead to poor overall health. Our circadian function plays a major role in the quality of our sleep, and research suggests that the physical environment can support better circadian function. Some research shows that residents with dementia in care homes experienced better sleep when exposed to increased light levels. The authors believe this to be the first study to look at the effect on a general population of older people not diagnosed with dementia.
