Chronic insomnia is usually due to some other problem such as:
It has been recognized for some time that underlying medical conditions like sleep apnea may be the cause of insomnia. The startling results of a pilot study published in Sleep conducted by prominent sleep doctor Dr. Barry Krakow and three colleagues in December 2012, reveal that link may be stronger than first thought.
The study was run to help answer an intriguing question: what causes an insomniac to wake up at night? There has been a lot of research on the various reasons an insomniac cannot get to sleep but the question of why an insomniac wakes up after finally falling asleep has not been studied the same way.
