How Turning On the Bathroom Light Ruins Your Sleep Cycle
That quick flick of the bathroom light switch at three in the morning feels harmless enough, but it can do far more damage to your sleep than most people realise.

It also explains why colour matters just as much as brightness, why going in complete darkness is not actually a safer alternative, and what kind of lighting setup allows you to see clearly enough to move safely without fully waking your body and brain out of sleep mode in the process.
