When the circadian gods align, entrainment ensues
BalancedCare™ Healthcare Lighting
Life is all about contrast, perhaps none as important as light and dark, day and night. As humans, we have evolved with blue sky and daylight as natural cues to keep our body clocks aligned with the 24-hour day. This healthy contrast between daylight and darkness allows our circadian rhythms to function as designed.
BIOS SkyBlue® communicates with the body on a biological level by providing a specific wavelength of light that stimulates our circadian system. It works in conjunction with traditional white light LEDs, so it maintains the appearance of white light in familiar color temperatures. SkyBlue® lighting systems can deliver the benefits of natural light without compromising light quality.
BIOS SkyBlue® lighting solutions deliver the health-enhancing blue-sky wavelength of the light spectrum. Recently discovered photo receptors in the human eye – photosensitive retinal ganglion cells or ipRGCs – contain the protein, melanopsin, which is highly sensitive to that blue-sky wavelength. When melanopsin is stimulated by light, the ipRGCs send a signal to the body’s master clock, telling it to reset its cycle for the next 24 hours. That signal triggers a variety of biological processes, including essential hormone production (e.g. early morning cortisol for alertness and nighttime melatonin to promote sleep). As a result, SkyBlue®, with its 490 nm peak in the light spectrum, can help provide an effective stimulus during the day to promote healthy circadian rhythms. SkyBlue® also peaks in the far-red wavelengths (near 660 nm) to help healthcare professionals better discern veins and visually diagnose and treat diseases through skin, such as cyanosis.
