Ever hear a satisfying pop during your chiropractic adjustment and wonder what it was? That sound is called cavitation, and no, it’s not your bones cracking! Here’s what’s really happening.
Cavitation is the audible sound that occurs when a joint is quickly separated during an adjustment. It’s caused by a rapid change in joint pressure, which releases tiny gas bubbles from the synovial fluid (the lubricating fluid in your joints). This is similar to the sound you hear when cracking your knuckles.
Not necessarily. While cavitation is common during adjustments, it’s not the goal. Some highly effective adjustments happen without any sound at all. The real focus is restoring motion and alignment, not chasing the pop.
Yes—when done by a licensed chiropractor. The popping sound is harmless and not a sign of anything breaking. It’s simply a natural release of gas.
The adjustment helps restore joint mobility, ease muscle tension, and stimulate your nervous system, which often brings relief—even if you don’t hear a sound.
Takeaway:
Cavitation might be a fun sound to hear, but the real benefit lies in what the adjustment does for your health and mobility.
