Joint cracking is one of those habits most of us acquire without thinking about it. In our third episode, we turn our attention to one of the body’s most common and least understood noises. Knuckles, backs, knees and necks all feature, along with the enduring warning many of us grew up with: “Stop cracking your joints, you’ll get arthritis.” Is there any truth in it? And why can cracking feel so strangely satisfying?

Hosts Katie Edwards and Dan Baumgardt turn this week to Clodagh Toomey, a specialist in musculoskeletal injury and chronic lifestyle-related diseases such as osteoarthritis, to give you the science behind the myths.
