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) and thus matches the sunlight spectrum in the extent of 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 wakefulness during the day. Circadian rhythms throughout the body are controlled by ganglion cells in the so-called suprachiasmatic nucleus (the so-called Non-Image Forming system of the eye – NIF), 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 maximum at 480 nm), which, unlike conventional light sources, Spectrasol contains To anchor the circadian rhythm, it is therefore important that the phases of light and night alternate during the day. It is also important that the difference in light intensity or illuminance (unit: lux) between day and night is at least 4 orders of magnitude and that our brain receives signals: “it’s day” by the presence or “it’s night” by the absence of short wavelengths (blue, cyan, green), and according to this it controls the internal processes in the body (during the day: alertness, activity; during the night: regenerative, restorative and immune processes, storage and sorting of information, etc.).
