From a Psychology Today online article:
For those with insomnia, however, the stressor appears to be the lack of sleep, and the desire for sleep becomes a stressor in itself. In other words, the fixation on getting sleep leads to feelings of stress over not falling asleep, which begins a vicious loop. According to a model first proposed by Kales et al. in 1976, patients 
can develop a conditioned fear of not being able to sleep, which puts them in a state of hyperarousal when they attempt to fall asleep. This makes their inability to sleep a self-fulfilling prophecy.
Insomnia is the most common sleep condition in the world, with half of adults globally reporting occasional episodes. Chronic insomnia, though far less prevalent, affects as many as 10 to 15 percent of the adult population.
Though these sleep problems are extremely common, the neurobiological mechanisms behind insomnia are not entirely understood. Research suggests that emotional stressors do play an outsized role in contributing to sleep problems, and it is well documented that mood and anxiety disorders are common comorbidities with insomnia. This seems like common sense. Emotional arousal, whether due to a state of anxiety or because of intrusive thoughts, makes it difficult to relax, thereby inhibiting one’s ability to either initiate sleep or get back to sleep after waking.

ABOUT THE MOTION: This House Prefers Reading Oscar Wilde to George Orwell Do we prefer satire or comedy? Do we take refuge in the serious or the frivolous? Do we understand the importance of being earnest or would we rather be in room 101? These two authors demonstrate well two powerful traditions in British literature, the comic and the satirical. They both of course share in each other’s art. Some would argue that during our present global crises we should look to Orwell more than ever, others would reach for the escapism of Oscar Wilde. In a new enterprise for the Cambridge Union, we are beginning our cultural debates – and this is our first. At least for a while.
The Sunbeam Tiger is a high-performance V8 version of the British Rootes Group’s Sunbeam Alpine roadster, designed in part by American car designer and racing driver Carroll Shelby and produced from 1964 until 1967. Shelby had carried out a similar V8 conversion on the AC Cobra, and hoped to be offered the contract to produce the Tiger at his facility in the United States. Rootes decided instead to contract the assembly work to Jensen at West Bromwich in England, and pay Shelby a royalty on every car produced.
