Dr. Ram Randhawa, a psychiatrist at the University of British Columbia’s Sleep Disorders Program, says about 30 per cent of Canadians struggle with getting to or staying sleep at any given time. The prevalence of insomnia does seem to be higher among women, he said.

For most people, sleep issues are a temporary problem brought on by stress or worry. For some, they can be a debilitating, life-long problem.
