Some insomnia sufferers find it difficult to sleep because
they are afraid of the dark, according to a new study.

Researchers at Toronto's Ryerson University studied a small group
of students and discovered that more poor sleepers than good
sleepers confessed to having a fear of the dark.

To confirm this, the researchers used a simulated bedroom to
measure the participants' blink responses to sudden noises in both
light and dark surroundings.

While the good sleepers became accustomed to the noise bursts, the
poor sleepers grew more anxious in the dark.

"We assume that poor sleepers become tense when the lights go out
because they associate the bed with
being unable to sleep," said Taryn Moss, the study's lead

"Now we're wondering how many people actually have an active and
untreated phobia."

It is estimated that up to 50 per cent of the population in the US
experience insomnia, while 19 per cent are thought to have chronic
sleeping problems.
