Lighting to Make You Feel Better: Improving the Mood of Elderly People with Affective Ambiences.

Kuijsters A, Redi J, de Ruyter B, Heynderickx I - PLoS ONE (2015)

Bottom Line: We hypothesized that ambiences with a clearly recognizable, positive affective meaning could be used to effectively mitigate negative mood in elderly.In line with our hypothesis we found that the activating ambience was physiologically more arousing than the neutral ambience.The cozy ambience was more effective in calming anxious elderly than the neutral ambience, as reflected by both the self-reported and physiological measurements.

ABSTRACT
Current lighting technologies extend the options for changing the appearance of rooms and closed spaces, as such creating ambiences with an affective meaning. Using intelligence, these ambiences may instantly be adapted to the needs of the room's occupant(s), possibly improving their well-being. We hypothesized that ambiences with a clearly recognizable, positive affective meaning could be used to effectively mitigate negative mood in elderly. After inducing a sad mood with a short movie one group of elderly was immersed in a positive high arousing (i.e., activating) ambience, and another group in a neutral ambience. Similarly, after inducing anxiety with a short movie one group of elderly was immersed in a pleasant low arousing (i.e., cozy) ambience, and another group in a neutral ambience. We monitored the evolution of the mood of the four groups of elderly over a period of ten minutes after the mood induction, with both self-reported mood measurements (every 2 minutes) and constant measurements of the skin conductance response (SCR) and electrocardiography (ECG). In line with our hypothesis we found that the activating ambience was physiologically more arousing than the neutral ambience. The cozy ambience was more effective in calming anxious elderly than the neutral ambience, as reflected by both the self-reported and physiological measurements.

pone.0132732.g005: Average change scores with the error bars reflecting the 95% CI for pleasure (left) and arousal (right) after the sad mood induction.The different bars represent the ambience to which the participants were exposed.

Mentions: Fig 5 presents the subjective pleasure and arousal change scores for participants exposed to the neutral and activating ambiences after the sad mood induction. The pleasure change scores are slightly higher for the participants in the activating ambience than for the participants in the neutral ambience; this effect is, however, not significant. The arousal change scores are reduced more under the neutral lighting than under the activating lighting; however also this effect is not significant. No significant effect of gender or time on the affective change scores, nor a significant interaction were found.
