Wondering what that cracking noise is in the joints while practicing yoga or stretching?
There are a few answers to this. When a joint is moved in or out of its regular positioning, gas escapes from synovial fluid in the joint. Ligaments stretching and releasing can also create sound.
According to international yoga teacher, Judith Lasater, sound comes from tendons moving across joints or from arthritic changes in the joints.
While it is usually normal, do pay attention. If symptoms change or if pain/swelling accompanies the popping or cracking noise, seek the advice of a qualified health professional. Otherwise, consider that crack a hello from your body to you!
