  • Human Centric Lighting (HCL) and Circadian Rhythm
    Apr 12, 2018

    Studies have shown that dynamic lighting solutions simulating the natural course of daylight significantly improve mood, concentration, productivity as well as alertness.

    Using intelligent lighting control systems and tunable light fixtures, HCL mimics the natural rhythms of light found in nature. It dynamically adjusts the brightness and color temperature of the lighting to imitate the natural course of daylight. This means activating cold blue light during the morning and slowly transitioning to a relaxing warm white light into the late afternoon and evening.

    During the morning, brightness levels are increased and light with a higher blue content is used. Blue light has a stimulating impact and addresses the cells in the retina that regulate our internal clock and our bodily functions. Blue light exposure cues the body to be in daytime mode, with its associated states of elevated alertness, improved attention spans, and reduced sleepiness.

    As the day progresses, HCL reduces blue light and delivers warmer red light in the afternoon and into the evening. Warmer light has a relaxing effect that promotes easier sleep by enabling the body to wind down. Exposure to warmer light is very important, as recent scientific studies have pinpointed blue light as a major factor suppressing the production of the hormone melatonin, which is instrumental at regulating the sleep-wake cycle.

    Using intelligent lighting control systems for HCL is just one simple yet effective strategy to help elders regulate their circadian rhythm. Among its many benefits, HCL can lead to a good night's sleep, resulting in significant improvements in overall health, quality of life and daytime functioning.
