The Skinny on: Cracking Your Knuckles

When someone tells you that cracking your knuckles will lead to arthritis, they're wrong.

What exactly makes that "popping" sound? When you crack your knuckles, or back, or whatever, you are pushing the joint into or out of its normal position. Joints are the meeting points of 2 separate bones. A thick liquid called synovial fluid is found between the bones. When you stretch, twist, push, or pull those bones apart, the pressure is reduced on that fluid, and bubbles form and quickly burst - making that familiar "pop."

Research from the Johns Hopkins School of Medicine shows that people who crack their back, neck, knuckles or knees generally have healthier joints than those who don't. Well, actually, people who tend to pop their joints are more likely to be more physically active than non-crackers.

So go ahead and crack away. It may be annoying to others, but at least it's not hurting you.

I crack my back and my hip joints daily. Good to know it's not a bad thing. My fiance is always joking I'm going to need hip replacements by the time I'm 35.

That is so funny, i have a friend who is such a couch potato and everytime she kneels down or bends her knees they crack like crazy and she thought it was really bad for her and the reason was because she did not do any excersice. I just have to let her know about this great info. You will always get the Truth from me!

I have to crack my wrists every morning. They feel like they're out of place if I don't do it.

Thanks fit - this is good to know. My husband wakes up and cracks all the knuckles in his hands. It drives me crazy but I also thought he was giving himself arthritis. But now I know he's not.
