Recent research from Flinders University highlights how the lighting in casinos, particularly blue-enriched light, can significantly affect gambling behavior. This type of lighting reduces sensitivity to losses, prompting gamblers to take riskier bets with less emotional response to losing. The study suggests that our biological sensitivity to different light wavelengths influences decision-making, as blue light can suppress melatonin and increase alertness and motivation. As gambling increasingly transitions online, these environmental factors continue to shape player behavior, encouraging prolonged engagement and risky choices. The findings call for potential regulatory measures to promote safer gambling environments by moderating lighting designs in casinos and digital platforms.
