I tell you what, I could do with some of this "blue lighting" each morning when I start work at 7.30. Being tested in a British school, Philips' blue-tinted light wakes kids up and makes them perform better.
In fact, previous tests have found that when the blue light is switched on, hyperactivity falls by 77 per cent; reading speed increases by 35 per cent and the number of errors actually fell by 45 per cent. The lighting system has four different light cycles for various times of the day (controlled by the teacher, naturally), with the blue setting reviving them when they're drowsy; a normal setting for most of the time; a whiter light for helping them concentrate, and a warmer color for relaxing the kiddywinks.
