Circadian photoreception influences loss aversion

10 months ago

Gambling behavior is influenced by circadian photoreception, particularly blue-enriched light, which reduces loss aversion.
Blue-enriched light (~480 nm) activates ipRGCs, affecting brain regions like the amygdala and habenula, which are involved in decision-making and reward processing.
Participants exhibited lower loss aversion under blue-enriched light compared to blue-depleted light, making them more likely to take risks.
Sex differences were observed, with women showing higher loss aversion than men across both light conditions.
The study suggests that exposure to blue-enriched light in gambling environments (e.g., LED screens) may encourage riskier gambling behavior by reducing sensitivity to losses.
