Sleep disorders will affect 40% of Canadians, pose serious health risks
'Over time, you incur a sleep debt which you can never fully repay,' says doctor
Roughly 40 per cent of Canadians will experience a sleep disorder during their lifetime, which can lead to serious health risks over time, according to sleep research.

Long working days, social and family responsibilities, irregular shift work and illness can lead to self-imposed sleep restriction, while an untreated or undiagnosed physiological condition may cause a chronic disorder that disrupts the quantity or quality of sleep, said Dr. Frank Ryan, a consultant to the Sleep Disorders Program at UBC Hospital.
Lack of sleep tied to serious health risks
Stimulants such as caffeine and energy drinks are at best a short-term solution to improve daily functioning in those suffering from sleep deprivation, said Ryan.
"The problem is over time, you incur a sleep debt which you can never fully repay.
"This is probably going to have long-term health consequences. That's the risk."

One of the more common disorders is sleep apnea, a condition in which an individual stops breathing during sleep, sometimes hundreds of times a night.
According to Ryan, roughly 15 per cent of men and five per cent of women suffer from sleep apnea. "The problem is that about 80 per cent of people with sleep apnea remain undiagnosed because we don't have adequate facilities for investigating and managing these people, unfortunately," he said.
Sleep apnea is associated with serious health conditions that include high blood pressure, heart failure, cardiovascular disease, depression and type 2 diabetes, according to the Public Health Agency of Canada.
Additional consequences of sleep disorders include a weakened immune system, impaired vigilance during tasks that require precision and attention, such as driving, as well as an increased risk of accidents in the workplace, Ryan said.
How much sleep is enough?
To be a little bit flippant, if I could paraphrase Pierre Elliott Trudeau, I would say, 'There's no place for TVs and smartphones in the bedrooms of the nation,'" said Ryan.
"If you wake up in the morning feeling refreshed, and if you're able to get through the day without feeling drowsy even when doing boring tasks, then you're likely getting good quality sleep," Ryan said.
"If not, and you're pursuing good 'sleep hygiene', then you may well have a sleep disorder that you need to talk to your doctor about."
