If you know someone who sleepwalks , or somnambulate yourself , you ’ve probably come across the estimate at some peak that you should never wake a noctambulist .

The approximation is an erstwhile one . Incredibly older , in fact , with   sopor specialist at Stanford University   Dr. Mark Mahowaldtelling LiveSciencethat it comes from an ancient belief that your soul leaves your torso while you sleep , and so waking a noctambulist would cause the sleeper to walk the lands soulless from then on . Which   – stop us if we ’re getting too controversial   –   does n’t voice like the most scientific basis for deciding whether or not to wake up a have intercourse one when they ’re roam the business firm at Nox .

We now recognise a luck more about sleep and sleepwalk , and the risks of arouse someone up vs letting them continue their nighttime manner of walking . Rumors that heat a noctambulist could   stimulate them to slip into a comatoseness , or have a heart attack , arenot correct . However , that does n’t mean you should decidedly wake them up , either .

" When someone is sleepwalking , they ’re stuck between mystifying quietus and light sleep and if you seek to wake them up , they will be very confused and disorientated , " Professor Harriet Hiscock of the Murdoch Children ’s Research Institutetold ABC .

" You ’re not going to give them a heart attack or toss off them , but by seek to ignite them up   – which is usually quite hard to do   – you could make them very agitated . "

Sleepwalking   – though disorientating , and at times distressing   – is not in itself harmful to your wellness , according to   UAMS Pulmonologist and Sleep Medicine Specialist   Dr Raghu Reddy , who adds that there are still other risks .

" It can induce problem indirectly mainly due to base hit business   – walk out of the house , jumping out of the window , using flatboat and kitchen knife , bumping into sharp objects , etc . ”

On the more extreme terminal , sleepwalkers have been known over the years todrive whilst sleepwalk , or   – like one 15 - year - old girl in 2005   – go up up a 40 metre ( 130 foot ) crane , before falling asleep again on the branch , before gratefully being rescued . Though ignite sleepwalkers in   such extreme circumstances ( or if you call back they might offend themselves without finding a jumbo Grus ) is probably justified , you should still do so carefully .

“ There is no consensus on what is the best advance when one encounters a noctambulism affected role . It is not dangerous to wake up a patient from sleepwalk , but expert who discourage it quote it is unsuccessful and extend to patient disorientation,”Reddy added .

“ seek to ease them back to bed without make forceful attempts . If unsuccessful , just take in nearly to check their safety and try again after some fourth dimension has go through . ”

Sleepwalkinggenerally happens during childhood , and is something that resolve by itself . However , should you somnambulate on a regular basis , or you ’re interested you may induce hurt to yourself or others it is deserving adjoin your physician .
