Do you ever read the news and other sources only to find contradictory advice. It happens with food all the time - at the moment butter is back in and salt ain't so bad. So I was interested in some sleep advice that came from 2 sources.

Firstly the BBC quoting from The Telegraph:

Lightbulb moment
The Telegraph reports that a sleep expert has warned that energy-saving lightbulbs could prevent people from sleeping because they emit more blue light than traditional bulbs.
Prof Debra Skene told the Hay Festival that people should try to dim lights in the hours before they go to bed so the body can prepare itself for sleep.
But she said that was more difficult these days because so many overhead incandescent tungsten bulbs had been replaced by energy-saving ones.
Prof Skene said: "If you want to reduce the effect on staying awake at night... you should try to have light in the room around you that's less blue."

Then Saga, fount of knowledge for the over 50's, quotes the Edinburgh Sleep Centre:

The secret to a sound night's slumber? Sleep in a blue room. That's the finding of a 2013 study, commissioned by Travelodge. Chris Idzikowski, sleep expert from the Edinburgh Sleep Centre, explains: 'There are specialised receptors called ganglion cells in the retina part of our eyes, which are most sensitive to the colour blue. These receptors feed information into an area deep in the brain that controls 24-hour rhythms, and affects how we perform and feel during the day. That interaction between light, sleep and wakefulness is supremely important.'

Of course if you're a tree-hugger you can ignore the Blue and go straight for the Red:

Red Light for a Healthy Nights Sleep

So there you have it, some more very clear ambiguous advice.
