Chapter 1: Is cracking my knuckles bad for me?
Is cracking my knuckles bad for me? Thanks for asking. Well, if you're asking that question, I'll take it as a given that you do personally crack your knuckles. As you're probably aware, many people find the noise pretty off-putting or just downright annoying.
You've probably also been told at some point that doing so will give you arthritis, most likely by someone already annoyed at you doing it. So just how seriously should you be taking that know-it-all? It's just so satisfying though, isn't it? Indeed, many people say they get a physical release from cracking their joints, leading to a feeling of looseness and a brief increase in mobility.
Chapter 2: What causes the satisfying noise when cracking knuckles?
But a lot of the time it's simply an unconscious habit. Various studies have been carried out on the prevalence of knuckle cracking, and they suggest that somewhere between a quarter and a half of all people do it. Men tend to do so more than women, according to the research. That's actually been a topic of some debate over the years.
One thing we know for sure though is that it has something to do with bubbles in the joints. Our knuckle joints are actually filled with synovial fluid which contains dissolved gases like oxygen, nitrogen and carbon dioxide. The fluid stops our finger bones from grinding on each other.
When you crack your knuckles, the bones are pulled away from one another, causing a sudden drop in pressure in the middle of the joint and allowing vacuum cavities or bubbles to form. Some scientists have speculated that the forming of these cavities makes the distinctive popping sound when knuckles are cracked.
Back in 2015, researchers at the University of Alberta proved it by pulling the fingers of a test subject inside an MRI machine. But more recent research suggests it's actually the collapse of those bubbles in the joints behind the noise rather than their formation. The study, published in Scientific Reports, was backed up by mathematical formulas.
Well, regardless of where the cracking noise comes from, there actually hasn't been a lot of formal research to know for sure. And some studies have relied on simply asking people whether they had been regular knuckle crackers for a long period of time.
But medical experts tend to agree that the health risks of knuckle cracking are minimal, particularly when it comes to a serious condition like arthritis. Some people with arthritis may find their joints crack because their cartilage has already been damaged, but that doesn't mean the cracking itself is the cause.
A recent women's health article reviewed by Dr. Elaine Husney of the Cleveland Clinic suggested that knuckle cracking can lead to joint laxity. Pain from that might sometimes be mistaken for symptoms of arthritis. So while there may not be any significant benefits to knuckle cracking, don't feel like you have to stop for health reasons.
Just try not to drive your friends, colleagues or family members crazy if you can help it. There you have it.
