How does Spectrasol light affect circadian rhythms and why is it important?

The Spectrasol lighting technology contains a balanced representation of all wavelengths in the 450-670 nm range, including full emission in the circadian or melanopic region (the cyan wavelength region in the 460-500 nm range) thereby mimicking the sunlight spectrum at 97%. The circadian rhythm depends on the regular alternation of light, dusk and darkness. Circadian rhythms are naturally occurring processes on a physical and mental level that follow a 24-hour cycle. The most well-known example of circadian rhythm is the alternation of sleeping at night and being awake during the day. Circadian rhythms are controlled throughout the body by ganglion cells in the so-called suprachiasmatic nuclei (the so-called non-image forming system of the eye), which are located in the brain and control the activity of the whole organism through the incoming light signal from the environment (mainly its blue and cyan wavelengths with a peak at 480 nm), and Spectrasol, unlike conventional light sources, contains them. To fix the circadian rhythm, it is therefore important to ensure the alternation of the light and night phases during the day. It is important that the difference in luminance or, in layman terms, light intensity (unit: lux), between day and night is at least 4 orders of magnitude and that our brain receives the signal: ‘it’s day’ through the presence, or ‘it’s night’ through the absence of short wavelengths (blue, cyan, green) so that it can control, according to this, the internal processes in the organism (wakefulness, activity during the day; regenerative, reparative and immune processes, storage and sorting of information, etc., during the night).
