I’m not a scientist but thought this was an interesting article in this week’s New Scientist magazine newscientist.com/article/mg21028111.400-blue-alert-the-dark-side-of-night-light.html?page=1 (link may only work at the moment for subscribers) that says there is strong evidence that blue-wavelength light at night may cause cancer tumours to grow faster.
They suggest that avoiding that kind of light at night could make a difference to breast cancer rates or tumour growth rates. Seems women who are totally blind only have half the risk of breast cancer than sighted people do, and that could well be why. They suggest using orange or red light late at night, for example.
It’s made me think, because I sleep in a room with a small blue light shining. Or I did until I read this article!

Sounds really interesting but I don’t want to register. Can you tell me what they mean by blue light? Thanks, Elinda x
I think they mean light that has a lot of the colour blue in it, e.g. very bright ‘daylight’ style bulbs, modern low energy fluorescent ones, bright white LED light. Anything that’s very bright and very white/blue-looking. Softer yellowy or reddish light at nighttime is better (though bloomin’ difficult to see with, I find!)
There was an article in the telegraph about energy saving lightbulbs containing cancer causing chemicles.
Seems everything is a risk eh.Don’t know what to believe and what not to lol.

this is interesting,
i read in one off the many booklets you get that you have a higher risk of breast cancer if you work nights… as i do, its somethink to do with the florescent lights and also when you sleep at night your body releases some hormone,(cant remember which one) but when you work nights under artifical lights, this hormone is not released… so really who know’s but very interesting…
