You know the feeling : You sit grouchy - legged or sleep on your weapon system for a small bit too long and it feel like your limb has been supplant by a rubbery , floppy peg . So , what ’s this all about ?
Most of us say this a limb " falling asleep ” or a “ drained leg ” , but scientist call itparesthesia , which translate from Greek to think something like “ besides sensation ” .
You might assume it ’s simply blood being turn off off from your brawniness , but it has more to do with the nerves . Sensory mettle are a spot like a bundle of cables that transmit sensational information through electrochemical pulsing to your head and spine . However , if enough pressure is pushed onto one of these cable , then they find it tricky to fire and send out signals .
Simply think of it like a garden hose . If you ill-treat on it , the period of water period . If you abstract the nerve fibre , it can result in the electrochemical impulses hitting a kink .
“ We think of brass roughage that run through the body as pathways of communicating , ” Lawrence Abraham , prof of kinesiology and wellness teaching at the University of Texas at Austin , toldQuartzin 2015 . “ We gather data and bring it to our central nervous organization from specialized sensorial receptors all over the body . If there ’s condensation of the receptive nerves , we but do n’t get any information , so it feel numb . ”
Once the numbness has gone and your sensation returns , you ’ll often experience bowling pin and needle . This is essentially your nerve firing off and panicking , still a bit confused from what they just experienced .
All of this can also occur if the limb ’s blood vessel flow is thin off because the nerves no longer have the necessary atomic number 8 to carry out their job . However , the blood is just part of the write up . Think about the sensation of hitting your “ comic bone ” . You get peg and needles when you hit your human elbow because the pressure is being use to the ulnar nerve , the nerve that travel between your finger and arm . As there ’s not much bone protecting this cable television service at the human elbow , a quick tap can induce tingles to shoot down to your paw .
bewilder the unmatched dead leg or pins and needles is nothing to worry about , but if you detect yourself having chronic paresthesia , it can be a sign of a serious neurological experimental condition . Most of the time , however , it ’s nothing that a quick hop around the room wo n’t remedy .
