Could your barn lights be quietly making your horse worse? In this episode of The Elevated Equestrian, Samantha Baer sits down with Dr. Barbara Murphy, Associate Professor at University College Dublin and founder of Equilume, to explore the surprising connection between light and equine health.

Barbara shares how barn lighting influences circadian rhythms, reproduction, metabolism, coat condition, behavior, and even whether horses experience jet lag. We talk about why blue light during the day can transform your horse’s wellbeing, how stable management practices often disrupt the body clock without us realizing it, and what every rider or barn owner can do to create a healthier environment. This conversation shines a light on one of the most overlooked aspects of horse care and performance.
