A vast survey conducted by the Canada’s Hautes-Rivières school board shows there is an increase in the number of students graduating from high school, though many aren’t getting enough sleep, according to CBC News, Montreal.

[Researchers found] 25 per cent of high school students say they rarely or never sleep at night, with 40 per cent getting less than eight hours of sleep.

For primary students, 30 per cent say they do not get enough sleep at night.
