A pioneering project in Costa Rica
An architect from the University of Costa Rica (UCR) is leading a pioneering interdisciplinary project in Costa Rica that investigates the effects of light exposure on human health and behavior. The study combines environmental sensors and surveys to analyze how different lighting patterns influence sleep, cognitive performance, mood, and other essential physiological processes.
The initiative is part of UCR’s scientific and technological research efforts, bringing together professionals from architecture, health sciences, neuroscience, and social sciences to generate applied knowledge that can improve environmental design and well-being in inhabited spaces.
Why is this study important?
Scientific evidence suggests that light plays a crucial role in regulating multiple human functions, including:
• Sleep–wake cycles
• Cognitive processes and mental performance
• Alertness and productivity
• Emotional state and mood
• Neuroendocrine rhythms that influence overall health
This research aims to deepen the understanding of these relationships within the Costa Rican context, providing local data that may help improve built environments and public health strategies.
Study methodology
The project uses a combination of light exposure sensors and structured questionnaires applied to participants from various settings. These tools make it possible to gather both objective data (light exposure levels) and subjective data (perceptions, habits, and reported effects), allowing for a comprehensive analysis of the interaction between light and human experience.
The research stands out for its interdisciplinary approach, linking architecture, psychology, and public health, which broadens the understanding of a phenomenon that affects all inhabited environments, whether urban, rural, or indoor.
Potential applications
Although the study is still ongoing, its findings could have applications in:
• Architectural and urban design — planning healthier and more comfortable spaces
• Public health — strategies to mitigate sleep disorders and stress-related issues
• Education and workplaces — recommendations for lighting conditions that enhance attention and well-being
• Environmental policies — guidance for regulations regarding natural and artificial lighting
This type of research may help position Costa Rica among countries producing scientific evidence aimed at improving quality of life in built and natural environments.
