I think pretty much everyone has experienced the pins and needles feeling, but what is actually happening to cause this feeling? And what determines how long it will take for the “effects” to subside?
In: Biology
It’s nerves getting squished, which confuses the message to the brain. That’s why we get the pins and needles; that’s literally your brain being confused and sending the wrong signals to your nerves.
Once the pressure on the nerve is released it goes back to normal.
If you think about it, it’s pretty clever. If we had no way of knowing when we’re doing damage to our nerves and no motivation to rectify the issue, we’d be pretty screwed.
