Due to this limitation of artificial lighting contribution compared to natural daylight, we need extra artificial blue light in the morning for proper signaling of the ipRGC. The only way to get the right physiological contribution from artificial light, is to increase the exposition to the blue component at the right wavelengths (bluish sunrises are another industry fairytale, and in a future article we will discuss the blue light myth, better be exposed to blue than become depressed).
As a conclusion, there are three main basic light/lighting contributors to healthy sleep, that can be achieved with adequate lighting systems and habits:
1.
2.
3.
I hope that these basic recommendations will raise awareness about the substantial interaction between light and health, and will contribute to improve your sleep hygiene, and ultimately your well-being, wellness and health. And sleep hygiene through lighting is one of the easiest and cheapest ways to reduce the burden of healthcare costs.
