I wonder if the spectrum difference in the light sources would also have an effect?
- taneq 8y agoAs a fictional example, in Asimov's "Prelude to Foundation" one of the locations (Dahl, a geothermal power district) offset the sweltering heat by running dimmer, reddish lighting, which apparently had a psychological effect on the inhabitants' perception of temperature. In real life, I wouldn't be surprised if offices choose to run high-colour-temperature lights in order to keep workers more awake and less drowsy (the exact effect that software like F.lux tries to offset).

Red-spectrum light doesn't influence that rhythm as much and from personal experience, will get you sleepy relatively quickly if it's late at night or you're otherwise exhausted. On the other hand, blue light keeps you awake however once you eat into the normal sleep time of your day enough, you'll start experiencing heavy eye strain, headaches and sore muscles rather quickly. (Personal experience is an Arduino-controlled LED strip with RGBW setting, which allows me to very precisely control the white temperature)
