Human Centric Lighting for the benefit of the elderly

Age leads to a natural evolution of the circadian cycle. For the elderly some changes in chronotype can be observed. This leads to a decline in the quality of sleep and a state of daily sleep. It’s actually a question of compensating the changes of the circadian cycle by the use of the light. It does a major role in its regulation. If blue light allows stimulation of brain activity, a yellow light can trigger a resting and a sleeping phase which recreate the benefit of the chromatic cycle of natural light. Accompanying the elderly in their daily lives, this dynamic compensates the evolution of their circadian rhythm. The study of dynamic LED lighting has made it possible to judge the potential of artificial lighting to reproduce the color and the cycle of natural light. This “Human Centric Lighting” becomes a factor for improving the elderly’s pace of life to ensure a standard of living.
