It's not really the "blue" part. It's the "forcing yourself to be awake when you shouldn't be" part that disrupts your sleep cycle. Driving at night when you should be in bed is so much more the problem than whatever color the light is. For you as human at least =)

That's the point -- the blue is to help break the cycle further and keep you awake, when your body insists otherwise!

I think OP is saying you are in the wrong for being awake during the night.

I'm pretty thankful that firefighters, paramedics and the police choose to break their night-cycle for me.

I'm very thankful that street lighting is helping to keep drivers awake.
