Do you like cracking your joints? And has anyone ever told you that you should stop, because it might give you arthritis?
Well, next time you’re being preached to about the dangers of cracking your knuckles, you can reply by saying that there’s practically no danger for your bones or cartilage. The cracking sound that you hear isn’t even caused by them!
It’s actually synovial fluid that’s behind the noise. This viscous fluid that lubricates your joints is full of small bubbles of air. When you crack your joints, these bubbles expand and pop, just as if you were popping bubble wrap.
