Circadian light offers numerous benefits, particularly in regions with limited sunlight. It helps mitigate symptoms of seasonal affective disorder (SAD), reducing depression and enhancing mood. Exposure to light that mimics natural daylight can regulate circadian rhythms, improving sleep quality and overall well-being. It also boosts energy levels, productivity, and motivation by mimicking the natural progression of sunlight throughout the day. Additionally, simulated natural light can enhance visual comfort and reduce eye strain, creating a healthier and more pleasant indoor environment.

Benefits of Circadian Light

The article "Influence of Simulated Natural Light on Mood and Well-being" studies the impact of artificial light mimicking natural sunlight on individuals' health and mood in Oslo. It addresses the need for such lighting in northern regions with low solar intensity, which can cause health issues like seasonal affective disorder (SAD). By using a prototype to simulate natural light, the study found positive psychophysiological effects on participants, indicating improvements in well-being, energy, and motivation.

The research revealed a pattern: when participants frequently used the Garden, there was a higher likelihood of perceiving the impacts of the simulated light and perceiving that light as natural. Additionally, this sequence would incentivize users to increase their visits to the garden.

The participants had difficulty differentiating the plants from the general environment.

Additionally, the perception of improvements in parameters such as "Creativity," "Natural Ambiance," and "Well-being" was satisfactory, with scores of 62%, 50%, and 61% respectively.

When participants in the experiment were asked to rate the garden light and experience in regards to the satisfaction, the results showed high scores of 3.67 (out of 5) for the LIGHT and 4.58 (out of 5) for the experience.

Not to mention how the space was among the favorite rooms in the building due to its social aspect that was linked often as a “meeting spot”. Also, when we asked a set of characteristics and feelings that could be associated with the light. Only the positive words scored high, which means the intensity and relation between these words/feelings with the light.
