Nearly a quarter of the population suffers nocturnal awakenings or “middle of the night insomnia”, on a daily basis, according to study released this week.
The survey of nearly 9,000 people also suggests that one person in three wakes in the middle of the night at least three times a week.
A study published in the April 1, 2008, issue of the journal Sleep confirms the persistent nature of insomnia and the increased risk of subsequent depression among individuals with insomnia. The study focused on 591 young adults, whose psychiatric, physical, and sleep symptoms were assessed with six interviews spanning 20 years.
