I was speaking about the part before sitting at the office, you are forcing your body in an unnatural way (after sleep).

All the offices I worked on had good lighting, so I never saw that problem, in a shared space or at home. At least at home I have few LEDs in each room with at least 900lumens each.

Office lighting is nowhere near the intensity of sunlight.

Office lighting - 320 - 500 lux
Full daylight but not direct sun - 10,000 - 25,000 lux
Direct sunlight - 32,000 - 100,000 lux

FYI: lumins and lux are different measures.

We don't tent to notice just how dark offices are compared to outside light levels because our eyes are good at compensating. But our brains seem to need bright light to keep our body clocks in check. That's why blind people tend to have this very problem at a much higher rate than sighted people.

But, just to be clear, I'm not trying to get anybody to change what they are doing. I just wanted to share what works for me.

Cheers.
