Many factors can contribute to sleepwalking, including:

  • Sleep deprivation
  • Fatigue
  • Stress
  • Anxiety
  • Fever
  • Sleeping in unfamiliar surroundings
  • Some medications, such as zolpidem (Ambien, Edluar)

Sleepwalking is sometimes 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
  • Restless legs syndrome (RLS)
  • Migraines
  • Head injuries

In other cases, use of alcohol, illegal drugs or certain medications — including some, antihistamines, sedatives and sleeping pills — can trigger sleepwalking episodes.
