Human Centric Lighting is an approach to lighting design that prioritizes people’s health and well-being by taking into account the natural patterns of human circadian rhythms. This approach improves human performance, comfort, health, and well-being.

While light’s primary effect on humans is vision. Human Centric Lighting recognizes that humans have an innate biological connection to the natural world and that light plays a crucial role in regulating circadian rhythms. Our bodies use light cues to control our sleep-wake cycle, hormone production, and other physiological functions. Our bodies function optimally when exposed to the right type and amount of light.

This knowledge is incorporated into lighting design by using light sources that mimic natural light spectrums and vary in intensity and colour temperature throughout the day. Lighting systems can be designed to be tunable or automated, allowing them to adjust throughout the day according to the natural light available.
