Interesting read on the impact of LED lighting to your body.
The summary is simple enough: LED lighting badly suppresses human melatonin production at night, which impacts sleep quality. Poor sleep quality has all sorts of nasty effects on human health - but it’s worse. Melatonin is also involved in the suppression of tumors and cancers. If your melatonin levels are low at night (from disruption or from simple night shift work), your risk of various cancers goes up by somewhere in the 30-80% range, depending on the cancer and study.
The article goes on to illustrate how LED lights produce white light. For the more technical you may know that the unlock for LED lighting was the development of cheap and efficient blue LEDs. We had green and red for a very long time. There are no white LEDs. The mass market solution of blue LEDs allowed the combination of RGB to give us what appears to be white light. But it isn't really white light, it is RGB light coming together. This difference may be more profound than we realize?
I also like the overall message about Human Centered Technology.
Do we exist to serve the needs of our technology, or does our technology exist to serve the needs of humans? It’s an important question!
