We all know that sound: the tiny, popping noise made from someone cracking their knuckles, neck, back, wrist, elblow, toes… you name it. And we all know the old wives’ tale that cracking your knuckles is bad for you. But is it true?


Either you pop your knuckles (neck, hips, etc.) religiously or you’re like my aunt who HATES the sound and freaks out every time somebody does it. For years, people have believed that this annoying yet cathartic habit leads to arthritis and lasting pain later in life. Now it’s time to put the rumors to rest, once and for all.


As you may or may not know, the space in between your joints is filled with a lubricating liquid called synovial fluid. Whenever you stretch a joint, small gas bubbles form in the synovial fluid and pop– this is the noise you hear. So is it bad for you?

I’ve been wrong about it all this time.
