What does it mean when your neck cracks on its own every time you tilt it?

When your neck cracks on its own while tilting, it's often due to the release of gas bubbles from the synovial fluid in the joints, a process known as cavitation. This is generally harmless and can occur due to normal joint movement or stretching. However, if accompanied by pain or discomfort, it may indicate underlying issues such as joint dysfunction or muscle tension, and consulting a healthcare professional would be advisable.
