"Circadian-informed" Light exposure to help your body shift to night work.

Light at the end of the tunnel for night shift workers

The use of circadian-informed lighting, where artificial lighting is synchronised to the natural biological rhythms or a person's 'body-clock', significantly improves quality of sleep and work performance for night shift workers, a major new trial has found. The trial is amongst the first tightly controlled in-laboratory studies to have simultaneously evaluated circadian-lighting effects on markers of body-clock timing, work-shift cognitive performance, and sleep following an abrupt transition to night shift work.

Here's a study that helped people shift to night work by using blue-enriched light and blue-depleted light (at the appropriate times). It looks like it improves alertness, cognitive performance, AND helped them get almost an hour extra of sleep, when compared to uniformly dim conditions during the shift to night work.

I wonder WHEN it makes sense to shift vs. not shift.
