Brain Emotion Affected by the Color of Light

The researchers investigated the instant effects of light and its color composition on the emotional processing of the brain using functional magnetic resonance imaging.

We all know that a sunny day can lift our mood. However, the mechanism of the brain which involves the influence of light is largely unknown.

Researchers at the Cyclotron Research Center (Liege University), the Center for Geneva Neuroscience and the Swiss Affective Science Center (University of Geneva), and Surrey Research Kehidupan Center on Sleep (University of Surrey) investigated the instant effects of light and color composition on emotional processing in the brain by magnetic resonance imaging functional. Their results show that the color of light affects the way the brain processes emotional stimuli.

Brain activity of healthy volunteers was recorded when they listened to “angry voices” and “sound neutral” and were exposed to blue or green light. Blue light not only enhances the response to emotional stimulation in the brain’s “sound region” and in the hippocampus which is important for the memory process, but also leads to tighter interactions between the sound region namely the amygdala which is the key region of emotional regulation, and the hypothalamus that is important for regulation biological clock by light. This shows that the functional arrangement of the brain is affected by blue light.

The sensitive influence of lighting on emotional processing may be different from its long-lasting effects on moods, but the current findings in healthy subjects have important implications for our understanding of the mechanism by which the lighting environment can improve mood, not only in light therapy. for mood disorders, but also in our daily lives by paying more attention to lighting in our homes and workplaces.

This discovery was published in Proceedings of the National Academy of Science .
