Impact of colour on depression, anxiety and stress levels of physically disabled patients in health care facilities

Physically disabled community in Sri Lanka is not receiving sufficient attention with reference to the conduciveness of their living environments. The patients who are harrowed with mobility impairments should be supported to overcome challenges which hinder the smooth functioning of day today physical activities while maintaining their psychological health by incorporating disabled-friendly, optimum healing design interventions. In view of this, an attempt was made to determine the impact of interior colours to reduce depression, anxiety and stress levels of disabled individuals. The investigation was executed with reference to wall colour of patient’s (n=15) bedrooms of a selected rehabilitation centre, at Ragama. The impact of three selected hues (blue, yellow and green) were tested by installing colour panels on the sidewall of the beds, allowing the participants to be exposed to each colour for three consecutive days. Depression, anxiety and stress levels of participants were measured using DASS-21. Impact of green colour was found to be more favourable to reduce depression, anxiety and stress levels of participants over blue and yellow. It is recommended to extend this study further to test different hues, shades and intensities of green colour with long-term exposure, to enhance psychological health and well-being of disabled patients in health care facilities
