Recognize this sound If you pop or crack your joints, you probably do. What happens to our joints when we crack them And is it bad for you Synovial fluid is this lubricantlike substance that’s found in between your joints. It kind of looks like an egg yolk. So when you stretch out your joint, you are releasing gas, and that gas forms a bubble and it collapses and pops. In order to crack the same knuckle again, you have to wait about 20 minutes for the gas to return back to that fluid. So how is that different from a pop you hear when.
You stand up quickly The sound you’re probably hearing then is the snapping sound tendons make when slide between muscles or over bones. When a joint moves, the tendon snaps quickly over and it makes a popping sound. So is the knuckle cracking habit safe Probably. Donald Unger was sort of a selfdescribed researcher who chose to pop the joints in one of his hands for 60 years, but not the other one. And he wanted to find out if popping your knuckles would actually give you arthritis. After 60 years of doing it, he found that.
