From BBC News:
Too many teenagers are damaging their health by not getting enough sleep and by falling asleep with electrical gadgets on, researchers say. . . .Get some sleep, kids. But not in class.
The Sleep Council, which conducted the poll of 1,000 teenagers, says gadgets in bedrooms such as computers and TVs are fuelling poor quality "junk sleep". . . .
Almost a quarter of the teens surveyed admitted they fell asleep watching TV, listening to music or with other equipment still running, more than once a week. . . .
Dr Chris Idzikowski of the Edinburgh Sleep Centre said: "This is an incredibly worrying trend. What we are seeing is the emergence of 'Junk Sleep' — that is sleep that is of neither the length nor quality that it should be in order to feed the brain with the rest it needs. Youngsters need to be taught a healthy lifestyle includes healthy sleep as well as healthy food. The message is simple: switch off the gadgets and get more sleep."
