Blue Light May Not Be As Disruptive For Our Sleeping Patterns

Contrary to some of the common beliefs, blue light may not be such disruptive for our sleeping patterns as it was originally thought, according to reports from University of Manchester scientists.
According to the team that is using dim, cooler, lights in the evening and along with that bright warmer lights in the day time may be more beneficial for our health.
Twilight is both dimmer and also bluer than daylight, they say, and the body clock also uses both of those features for determining the appropriate times for becoming asleep and awake.
Current technologies have also designed for limiting our evening exposure to the blue light, for example when changing the screen colour on mobile devices, it may therefore be sending us mixed messages, they argue.
This is because of the small changes done in brightness which they produce and these are accompanied by different colours that more resemble day.
The research, which was earlier carried out on mice used some specially designed lighting that enabled the team for adjusting colour without changing the brightness.
That also showed blue colours that produced weaker effects on the mouse body clock and then equally bright yellow colours.
The findings as said by the team have some important implications for the designing of lighting and visual displays that intended for ensuring healthy patterns of sleep and also alertness.
The study has been published in Current Biology and has been funded by the Biotechnology and Biological Sciences Research Council.
