Sleep disturbances are very common. At least 4% (one in 25) of the male population and 2% of women suffer from clinically important obstructive sleep apnea (snoring and stopping breathing). Approximately 30% of the population complains of insomnia, and in 9% insomnia is severe (occurring at least 15 days in a month).
Sleep medicine has now become an important part of the medical science. The current classification of sleep and wake disorders describes 88 conditions affecting people of any age.
The Sleep Medicine website provides basic information on the most common conditions, their diagnosis and treatment.
