Turns Out, Blue Light May Not Really Disrupt Our Sleep

Yep, scientists make mistakes, too.

'Blue light = bad' is what we've been conditioned to believe. But now, a new study says that may not be true. 

Furthermore, researchers say dim, cooler lights in the evening and bright, warmer lights during the day may be more beneficial. The research says twilight is dimmer and bluer than daylight, and it makes sense that it would be better for us. In fact, according to the study, the body uses light to determine when we should be asleep and awake.

"We show the common view that blue light has the strongest effect on the clock is misguided; in fact, the blue colors that are associated with twilight have a weaker effect than white or yellow light of equivalent brightness," said University of Manchester's Dr. Tim Brown.

"There is lots of interest in altering the impact of light on the clock by adjusting the brightness signals detected by melanopsin but current approaches usually do this by changing the ratio of short and long wavelength light; this provides a small difference in brightness at the expense of perceptible changes in color."

The study emphasizes on the 'may' aspect of the research... so, we'll have to wait until we can fully confirm things.
