Some sleepwalkers don't seem to feel any pain

During a sleepwalking episode some people can suffer horrendous injuries without noticing or waking up.
In extreme cases, sleepwalking can be a life-threatening condition - especially when the oblivious sleepwalker ends up falling down stairs, tripping over objects or jumping out of windows.

It would seem to stand to reason that sustaining such an injury would wake the person up, but according to a new study by researchers in France, a person sleepwalking may experience no discomfort or pain whatsoever, no matter how severe their injuries, at the time of the mishap.

"Our most surprising result was the lack of pain perception during the sleepwalking episodes," said principal investigator Dr. Regis Lopez from the Hospital Gui-de-Chauliac in Montpellier, France
"We report here, for the first time, an analgesia phenomenon associated with sleepwalking."

An analysis of 100 patients with a diagnosis of sleepwalking revealed that, of the 47 who reported injuring themselves while asleep, only 10 actually woke up at the time as a result of the pain.

One patient even suffered severe fractures after jumping out of a third floor window but had experienced no pain or discomfort at all until they woke up later on in the night.

"We hypothesize that a dissociate state of arousal may modify the components of sleep-wake behavior, consciousness, and also pain perception," said Dr. Lopez.

Patient: Doc, I broke my arm and I am in severe pain. Doctor: Yes, your MRI confirms this. I am prescribing you 14 sleep-walking sessions. In reflection having broken my leg, I did notice that apart from waking with pain, that while I was in a deep sleep I felt no pain that I can recall.

One patient even suffered severe fractures after jumping out of a third floor window but had experienced no pain or discomfort at all until they woke up later on in the night. Where did the patient wake up...mangled up on the pavement below.. he did not wake up at the time because he was unconscious from falling from a third floor window. Would like to see what he did do when he recovered, apart from scream! This "STUDY" is ridiculous.

Every time I sleepwalk I instantly wake when I walk into something. That's a good thing.

You do? I thought that crazy unwakeable deep sleep always came with it. Which is weird because as a single mom im an incredibly light sleeperthe rest of the time someone pulls up quietly on the street n i wake up. Are you being serious lol do you often wake up while walking? Im just curious about the causes lol because ive been caught leaving these premises by others but am usually alone n that scares me i want to know where i go n what i do at night lol because from what i heard i conversate interact and am not always recognised as sleeping until later. I think this article is correct i mean ... [More]

Yesterday in Copenhagen a 12 year old girl sleepwalked out of her bedroom window from 6th floor hitting the sidewalk made of stone and concrete. She barely got a scratch. Some sleepwalkers should consider some kind of safety string attached to their ancle and bed.

I am so glad that I don't sleep walk anymore.
