"This raises questions about the role of lighting in environments like casinos or online gambling platforms."Gambling scenarios were played out under different lighting conditions. (Lander et al., Sci. Rep., 2025)The researchers assembled 15 volunteers, aged between 18 and 27, and asked them to complete hypothetical under a variety of lighting scenarios: some under blue-enriched light, and some under blue-depleted light. The brightness remained constant in each case. Before they began, participants were also told they could receive a real $20 reward, depending on their performance in these tasks., The researchers think circadian photoreception, which is our non-visual response to light, is playing a part here. The level of blue spectrum light may be activating specific eye cells connected to brain regions in charge of decision-making, emotional regulation, and processing risk versus reward scenarios., ScienceAlert reports: Casino lighting could be nudging gamblers to be more reckless with their money, according to a new study, which found a link between blue-enriched light and riskier gambling behavior. The extra blue light emitted by casino decor and LED screens seems to trigger certain switch.
