Causes
By Mayo Clinic staffVarious factors can contribute to sleep terrors, including:
- Sleep deprivation
- Fatigue
- Stress
- Anxiety
- Fever (in children)
- Sleeping in unfamiliar surroundings
- Lights or noise
Sleep terrors sometimes are associated with underlying conditions that affect sleep, such as:
- Sleep-disordered breathing — a group of disorders characterized by abnormal breathing patterns during sleep, the most common of which is obstructive sleep apnea
- Migraines
- Head injuries
In other cases, use of alcohol, illegal drugs or certain medications — including some antihistamines, sedatives and sleeping pills — can trigger sleep terror episodes.
