Why do joints crack? The explanation according to National Geographic

A cracking or popping joint is a common phenomenon. According to National Geographic, this is caused by small gas bubbles in the joint fluid that collapse. This process is known as cavitation and is usually not visible to the naked eye.

Although cracking is often harmless, it can sometimes indicate an underlying problem. National Geographic emphasizes that regular cracking can sometimes be a sign of osteoarthritis or another condition. If in doubt, it is advisable to consult a doctor.

The causes of popping sounds can vary, from muscle contractions to subtle joint movements. National Geographic reports that research is still being conducted into the precise mechanisms behind this phenomenon.
