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.

Average change scores, including the 95% CI as error bars, for SCR (a) and HR (b) after the anxious mood induction.The different bars represent the different ambiences in which participants were immersed.

pone.0132732.g009: Average change scores, including the 95% CI as error bars, for SCR (a) and HR (b) after the anxious mood induction.The different bars represent the different ambiences in which participants were immersed.

Mentions: With respect to the physiological measures, we found a significant effect of ambience on SCR (F(1, 32) = 4.43, p = .043 η2 = .12). As expected and in line with the SAM arousal ratings, the SCR affective change values of the participants in the cozy ambience group were significantly lower than the SCR affective change values of the participants in the neutral ambience group (as is illustrated in Fig 9). The HR also decelerated after the anxious mood induction for the participants in the cozy ambience, while that was not the case for the participants in the neutral ambience group (see also Fig 9). This effect was however not significant. No significant effects were found on the HRV measures.
