3.3 million suffer insomnia.

Ottawa -- An estimated 3.3 million Canadians aged 15 or older, or about one in every seven, have problems going to sleep or staying asleep, and thus are considered to have insomnia, according to a study of Health Reports published by Statistics Canada. Based on the 2002 Canadian Community Health Survey the article reports that under one-fifth (18%) of these people average less than five hours of sleep a night. In contrast, only 2% of people who did not have insomnia reported less than five hours of sleep per night. The study found close ties between insomnia and stress, as well as chronic conditions such as arthritis that involve pain. Other factors noted were: physical and mental health, lifestyle and socio-economic conditions.

There are no standard criteria for defining insomnia, although the most common definitions are based on frequency. For the CCHS, respondents were asked how often they had trouble going to sleep or staying asleep. Those who answered either "most of the time" or "all of the time" were considered to have insomnia. A link between obesity and insomnia was also found.
