Why Do People Crack Knuckles? Is It Harmful?

Knuckling cracking is the sound produced when the joints of your fingers are stretched. These joints, called synovial joints, are lubricated by synovial fluid made up of dissolved gases – mostly nitrogen. When we pull or bend our fingers, we stretch the synovial fluid-filled capsule. This decreases pressure within the gas-filled fluid, causing a tiny nitrogen bubble to form and then instantly burst. The bursting bubble is what causes the crack that we hear.
