Special blue-tinted lighting installed in UK school to wake up drowsy pupils | A British high school has installed special blue-tinted lighting to combat the boredom that teenage students often go through in the classroom.
The system, developed by Philips electronics corporation, is being tested in two
laboratories at Epsom and Ewell High School in Surrey, southeastern England .
The SchoolVision technology aims to compensate for a biological quirk of teenagers,
which means their body clocks tend to lag behind those of younger children and
adults. They find it harder to learn early in the mornings and perform best in
the evenings. The body clock, which governs waking and sleeping cycles, is kept
in time with night and day by cells in the retina, which respond most strongly
to the blue part of the spectrum. When stimulated, the cells trigger the release
of an "alertness" hormone, melanopsin. The hope is that exposing students to a
dose of blue light will help to wake them up. "Lighting has not been seriously
considered as a factor in performance until now," News.com.au quoted Effie Konstatinou,
a psychologist at City University , London , who is leading the research, as saying.
"We know that there's a direct link between lighting, well-being and performance,"
Konstatinou said. The system, which is already used in 20 schools in Germany ,
and more than 80 classrooms in The Netherlands, has four settings: focus, energy,
calm and normal. Under focus and energy, the lighting is more intense and contains
extra blue, and the red-tinted calm setting is designed to settle a class towards
the end of the day, when disruptive behaviour is most frequent.
