There is a 7 per cent increase in performance when cool light is used in a workplace, according to research presented at the Wellness 19 summit this week in London.
Delegates heard Phill Bell PhD, operations director and Josh Jackman PhD, senior science consultant, both from ART [Assessment, Research, Technology] Health Solutions, explain that this statistic was the average in a pilot study they conducted.
A further controlled study showed that there was a 2 to 3 per cent improvement in well-being with warm lighting.
Bell and Jackman were presenting a session on how workplace experience could be improved by using data-driven insights from the office environment to retain and attract top talent and reduce absenteeism.
Their findings also showed that a temperature of 18 degrees Celsius increased discomfort but had no impact on cognitive performance, while 21-24°C was the preferred range for thermal comfort and cognitive performance and 27°C increased discomfort and impaired cognitive performance.
Similarly, they found that 85 per cent of employees said no noise was best for performance and concentration but there was also a rise in well-being with biophilic sound-masking solutions.
Bell and Jackman said the research was continuing within the company in which they were conducting it and they would present more findings in due course.
Wellness 19 was held in Bishopsgate, London, by events company Unwired.
