Many Canadians lack sleep, says Statistics Canada.

Sufficient sleep is a struggle for about a third of Canadian adults, according to a Statistics Canada report released Wednesday.

The reoport on duration and quality of sleep focuses on people 18 to 79 years old during a six-year period. It provides recent estimates of the duration and quality of sleep, and the percentage of Canadians surveyed who adhere to these sleep guidelines:

Seven to nine hours per night at 18 to 64.

Seven to eight hours per night at 65 or older

The results suggested 43 per cent of men and 55 per cent of women in the 18 to 64 age group reported trouble going to sleep or staying asleep "sometimes/most of the time/all of the time."

About two-thirds of survey respondents reported the recommended seven to nine hours, and the other third reported less than seven hours, with sleeping more than nine hours cited as being rare.
