Abstract

Untreated stress is one of the prominent near-to-lead mental health problems. To address the mental health issue, the effect of ambient lighting was investigated in the study to determine its effect on a person’s stress and relaxation conditions. The coloured ambient illuminations consisting of red, green, and blue (RGB) hues were chosen with care to meet the study’s purpose. Digit Span Test and a piece of loud music were chosen as stressors to induce stress while calm music was used to stimulate relaxed conditions during the experimental session. A physiological parameter was monitored via a Galvanic Skin Response (GSR) sensor in classifying the stress and relax states. At the end of the experiment, the participants were interviewed verbally by the experimenter on their feelings after being exposed to the ambient illuminations. Using within-subject design as the experimental setups, the sensor’s output was then quantified using a series of developed questionnaires. As a result, the participants experienced higher anxiety and reactance under the stress condition compared to the relaxed condition through the questionnaire. Interestingly based on GSR reading and quantitative analysis using questionnaires, data showed that the participants experienced the most relaxed state when being exposed to green-coloured ambient illumination (66%) compared to other colours. In contrast, blue-coloured ambient lighting elicited the most stress state through the analysed data collected from GSR reading (33%) and red-coloured ambient lighting (66%) from quantitative analysis using questionnaire and qualitative analysis (interview). Future studies might utilize different coloured ambient illumination for the same settings.
