Sleepwalking (also known as Somnambulism) is when a person walks around or takes part in other activities while still appearing to be asleep. Sleepwalking can range from a person simply sitting up in bed, to walking around, getting dressed or even driving a car whilst seeming to be asleep. Sleepwalking usually last for a few minutes, though some people can sleepwalk for half an hour or more.

What causes a person to sleepwalk?

The cause of sleepwalking is usually related to tiredness, stress or sometimes mental disorders, though it can be caused by medications, drugs and alcohol. Sleepwalking is most common in children, but can happen to people of all ages. It seems to run in families as well. Most people do grow out of sleepwalking.

What should I do if I sleepwalk?

• Try to go to bed at the same time every night, having a sleep routine may help to eliminate sleepwalking that is caused by tiredness.
• Don’t drink too much before you go to bed as this might trigger sleepwalking.
• If possible, a bedroom on the ground floor is a good idea and make sure that windows cannot be opened.
• Move anything that you could trip over or anything that could cause you harm from the bedroom.
• If you are on any medication, talk to your doctor about it as some medications can cause some people to sleepwalk.
• Hypnosis has helped some people stop their sleepwalking.
• Don’t feel ashamed about sleepwalking, about 18% of people sleepwalk at some point in their lives.
• If you sleepwalk often and for a long period of time, or if you are likely to do something dangerous talk to your GP who will advise you on further action.
