What happens when you sleepwalk?
"The technical name for sleepwalking is “somnambulism†and it is essentially when a person walks around whilst in deep sleep. It’s most common in children but is also suffered at times by adults, especially by those who are stressed or sleep deprived. Sleepwalkers don’t usually wake up whilst they’re sleepwalking and generally have no recollection of it when they wake up in the morning. If your partner is a sleepwalker, you may well find they’re difficult to wake up during these episodes, so unless they’re in immediate danger it’s best to just let it pass.
People who sleepwalk will likely carry out a range of complex tasks during their sleepwalking, such as sitting up in bed, walking around, or even leaving the house. In very extreme cases they may try to carry out familiar jobs they routinely complete when awake such as cooking or cleaning. Obviously carrying out such tasks when you’re asleep is dangerous so if this sounds like you it’s well worth asking your partner to wake you up if they can, as well as making an appointment with your GP.
Amongst the population as a whole, as many as 15% of people will sleepwalk regularly. In adults, sleepwalking can be triggered by a number of factors including certain drugs, alcohol consumption or illnesses. In children, sleepwalking can be the result of a high temperature, for example if they have a fever, although sleepwalking is so common in kids that the vast majority will have sleepwalked before secondary school age. Interestingly, sleepwalking is more prevalent in children who suffer with sleep apnea as well as those who experience bedwetting. They are also often related to night terrors and like most sleep disturbances tend to run in families.
What are the symptoms of sleepwalking?
Sleepwalking usually takes place during deep sleep but can also happen at lighter stages of sleep. It’s also most common in the hours immediately after dozing off, and sleepwalkers may be partially awake whilst it’s happening.
Although typically characterised by getting out of bed and walking around, there are other symptoms that may be present alongside sleepwalking too. These include:
- Little or no memory of the sleepwalking episode
- Talking whilst asleep
- Difficulty in waking up the sleepwalker whilst they are sleepwalking
- Screaming, shouting or night terrors
- Unusual behaviour such as hiding in a cupboard (more likely in children)
- Episodes of violence whilst asleep, particularly if attempts are being made to wake the sleepwalker up
