Do We Need Human-Centric Lighting?
Science tells us our bodies respond to the natural stimuli of light. Clearly, we sleep at night when it's dark. We also have an internal clock of sorts referred to as the circadian rhythm, and our bodies respond to different types of light during the day. Bright, intense, cooler-toned light, like that of the noonday sun, tends to awaken and energize us. Warmer, amber, and red tones, like those of the setting sun, signal our bodies to wind down and prepare us for sleep.
The wrong light can throw off our natural rhythms. Imagine if you were subjected to bright fluorescent lighting in your bedroom, like that in many offices at 11 PM – it's not likely you would feel relaxed or ready for sleep. With new technological solutions, we can now make artificial light follow natural patterns that are in tune with our bodies.
