Sleep deprivation, sleep apnoea, sedatives, alcohol, stress and certain illnesses, including psychiatric illnesses such as post-traumatic stress disorder, may increase the risk of sleep walking. It is more common in children, who will often outgrow the behaviour.
Treating the underlying cause may resolve sleep walking, meaning for some it may be as simple as getting more sleep, avoiding certain medications and improving lifestyle balance.
• Approximately 1% of pre-school aged children and 2% of school aged children walk in their sleep at least one night per week
• Approximately 4% of adults sleepwalk
• Men are more likely to become violent in the course of a sleepwalking episode
• Sleepwalking may have a genetic component. Identical twins are more likely to sleepwalk, and a person with a close relative who sleepwalks is 10 times more likely to sleepwalk themselves
• The old myth about not waking a sleep walker is just that: a myth. It can be very dangerous not to wake a sleep walker, as they could harm themselves or others
• Creating a safer sleep environment is essential for sleep walkers. Locking doors and windows and removing access to sharp objects are important precautions
• A sleep walker will normally have their eyes open and fixed in a blank stare
