Health Tip: Nightmares Keeping You Up?

Some possible reasons for bad dreams

(HealthDay News) -- While nightmares mostly affect children, even adults have an occasional bad dream.

Why do nightmares happen? The U.S. National Library of Medicine offers this list of possible causes:

  • Being stressed or anxious, often resulting from a significant life event.
  • Withdrawing too quickly from alcohol use, or drinking too much alcohol.
  • Having a sleep disorder, such as narcolepsy.
  • Being sick with a fever.
  • Having a side effect or reaction to a drug.
  • Eating too close to bedtime, which raises your metabolism and increases brain activity.
