Is cracking your back safe: Science explains the risks and relief

Cracking your back can feel satisfying and relieve stiffness, but is it actually safe?

The sound occurs when gas bubbles in the synovial fluid collapse. While this can give temporary relief from stiffness, it does not necessarily indicate proper joint alignment. Frequent cracking can strain muscles, stretch ligaments, and increase the risk of joint instability over time.While occasional back cracking is safe for most people, repeated or forceful cracking may cause:The popping sound, called crepitus, occurs when gas bubbles in joint fluid collapse due to changes in joint pressure.
