I just stumbled upon this scientific article which basically says that:
Blue light from devices and certain lights can accelerate skin aging by producing harmful particles damaging DNA and activating aging-related genes.
This just confirms what I intuitively promote for several years now, which is lighting that is adapted to humans and which is mimicking the natural circadian rhythm.
By exposing ourselves constantly to artificial blue light, we are not only damaging our eyes but also our skin, as it seems.
More research is needed, but this is quite a concerning finding.
My vision is that with IOT we will develop technology that mimics nature: lighting, music, air conditioning, heating, alarm clocks, maybe even water temperature. The ultimate smart home will mimic nature.
