What Happens When We Crack Our Knuckles?
You want to know what happens when you crack your knuckles, right? Well stay tuned! I'm Nick welcome to All Our Questions where I search the internet for questions that we all want answers to and I answer them. Today's question is, what happens when we crack oour knuckles? We're gonna find out and we're starting right now! The process of cracking your knuckles is technically called tribonucleation. It's never been fully understood as to what exactly happens when we crack our knuckles and there's been some disagreements on if it actually causes damage or not. I'm sure you've also heard the theory that cracking your knuckles can lead to arthritis or other bone problems but nobody has actually been able to prove that theory and before we get too far into this let me know in the comments down below if you are a knuckle cracker. Some people hardly ever crack their knuckles at all, other people crack their knuckles all the time. A study conducted on one such knuckle cracking addict actually revealed what exactly happens when we crack our knuckles and why it is that we hear that popping sound... Of course, mine are not popping now... There we go...when we do.
A researcher at the University of Alberta volunteered to have every one of his fingers cracked by sticking them into a custom made finger cracking device. For this example I'm going to use a phone charger but what they did is they basically wrapped cable around his finger and they hooked up to a contraction of sorts and this contraption just pulled on his finger until it popped. I don't know about you but to me that sounds terrifying. It sounds like you're putting yourself through a medieval torture device but because of this person's bravery an MRI scanner was able to detect or able to see exactly what was happening in real time when his fingers were popping.
Previously it was believed that the popping sound was greeted by a bubble of air collapsing around the joints but now we know better, here's what happens: Our joint are covered with the liquid known as synovial fluid which lubricates them and helps them move around. When we exert enough force on our joins they separate. When this happens pressure inside the synovial fluid drops dramatically which allows a bubble of gas to form inside the fluid. It's the creation of this bubble of gas that actually makes the popping sound. One of the researchers actually referred to it as how the bubbles appear when you pop open a carbonated beverage. And for the record, popping your knuckles will not give you arthritis but according to a study that was done a while back it can possibly cause hand swelling and a loss in hand strength over time but the jury is still out on that so..
