Is It Harmful to Crack Your Joints?
Knuckle cracking - a practice that's divisive, to say the least. Some people find relief in it, while others can't stand the sight. You might've heard that cracking your knuckles breeds enlarged joints or triggers arthritis, but is that just an urban legend?
Let's bust some myths with the help of orthopaedic surgeon Kim L. Stearns, MD. She explains that knuckle cracking releases gas bubbles - mostly nitrogen - from the space around your joints. The sound is generated as these bubbles are compressed, but researchers are still unsure if the noise comes from gas bubbles forming or being released.
So, if you're cracking your knuckles right, you won't damage your joints. But that doesn't mean there aren't risks involved. Proper technique is crucial. Don't apply too much force, and always keep direction in mind. If you feel pain, swelling, or witness crooked fingers, it's advisable to visit a doctor as you might've injured a ligament or dislocated your finger.
In 1999, a study found that frequent knuckle cracking can lead to weaker hand grips and more hand swelling. However, a 2017 study found no difference in grip strength between crackers and non-crackers. The same study did identify a difference in metacarpal head cartilage thickness, suggesting potential osteoarthritis, but there's no concrete evidence linking knuckle cracking to its cause.
Overall, the existing research on knuckle cracking is thin, but currently, there's little cause for concern about long-term side effects. But remember, consistency matters. Don't let knuckle cracking become compulsive or forceful.
In conclusion, knuckle cracking doesn't bring either health benefits or harm. It's just a habit for some, a stress reliever for others, and a cause for amusement for some. But take it easy, and there's nothing to fear from an occasional crack.
