The design of lighting does more than just overcome darkness. According to David McNair, after food, lighting is the most important factor for supporting physical wellbeing. This is particularly so for older people and people with dementia. McNair, a lighting engineer, has written a book on the topic, Enlighten: Lighting for older people and people with dementia. It is written with care professionals, engineers, architects and designers in mind. Dementia and acquired brain injury can affect visual perception and well designed lighting can help overcome some of these issues. Aged Care Insight has an article about the book and also has a podcast interview with one of the book’s authors.
Editor’s note: The picture shows how the line shadows of the arches fall across the pathway. These can look like steps, or the distant arches can look too small to walk through. Not knowing if there are steps or if the arches are big enough can affect confidence in getting out and about. However, from personal experience, this is a very pleasant area to walk in the evening (Brisbane South Bank).
