Sponsor: James Housefield, Ph.D. Department Of Design Light pollution, the excessive and misdirected use of artificial light at night, not only obscures stars but also disrupts the human body's natural sleep-wake cycle and overall health. In response to these impacts, our group developed an interactive board game that explores how everyday outdoor lighting decisions affect human health and community environments. At the biological level, exposure to artificial light at night interferes with the body's circadian rhythm by suppressing melatonin production, making it harder to fall asleep and stay asleep, which contributes to sleep disturbances and chronic sleep-related problems in many communities. Outdoor lighting that spills into homes, parks, and neighborhoods often lacks shielding or purpose, causing residents to experience reduced sleep quality and altered sleep patterns. This environmental stressor has been linked to increased stress, mood disorders, and other health concerns as disrupted circadian rhythms affect both mental and physical well- being. The game immerses players in real-world scenarios where lighting decisions impact human health, community environments, and nighttime experiences. Our game not only informs but also encourages thoughtful action and sustainable design choices. Evaluating Vignettes Usage in Moral Judgment Research: A Scoping Review
