What is Human-Centric Lighting?

Human-Centric Lighting is a lighting approach that is designed to improve people's health, well-being, and performance by mimicking natural light patterns. The concept recognizes that the human body has an internal biological clock, called the circadian rhythm, which regulates our sleep-wake cycle, hormone production, and other bodily functions. This internal clock is influenced by external cues such as light, and Human-Centric Lighting aims to optimize these cues to promote our health and well-being.

Human-Centric Lighting involves using lighting that can be adjusted in color, intensity, and timing to match the natural patterns of daylight. For example, during the day, the lighting can be set to a cooler, bluer color temperature, which helps increase alertness and productivity. In the evening, the lighting can be set to a warmer, redder color temperature, which promotes relaxation and sleep.

Studies have shown that Human-Centric Lighting can have a positive impact on people's mood, cognitive function, sleep quality, and overall well-being. It has been used in a variety of settings, including schools, hospitals, and workplaces, to improve the environment and promote better health and performance.
