FOX - It's not just kids who are afraid of the dark, the phobia may affect adults too.

Canadian researchers find the fear may be one of the triggers for insomnia.

They used loud noises to measure blink responses among college students in both light and dark settings.  They found good sleepers got used to the noises, while students who had trouble sleeping were more easily startled in the dark.

Further research is needed to confirm these results.
