Lighting influences perceived temperature
A scientific study from the University of Pennsylvania has shown that the lighting quality in a room affects a person's perception of its temperature. Short-wavelength blue light makes individuals feel that the room is approximately 0.7°C cooler, while long-wavelength red light creates a quicker sensation of warmth. The study explains that changes in the light spectrum, rather than the color itself, influence thermal perception. This finding can be applied to reduce energy consumption by adjusting lighting conditions to enhance thermal comfort without altering the actual temperature. Plans are underway to expand the research in the future to better understand how light interacts with other environmental factors.
