Besides causing fatigue during the following day, going to bed late may cause other unwanted after effects. A new study still in its preliminary stages suggests that hitting the hay late can cause nightmares. Researchers studied at group of 264 college students. Each student completed a survey about their dreams, including nightmares, which was then compared to the Van Dream Anxiety Scale.
The link that was found between bedtime and frequency of nightmares suggests that a person’s body clock, or circadian rhythm, may be linked to nightmare severity and frequency. Although this research is still preliminary, the researchers admit that the topic of nightmares is of high interest and importance, and there is much room for subsequent experiments to be done in this area.
