Should You Stop Cracking Your Knuckles?
Summary
Cracking your knuckles is generally harmless and does not cause arthritis or weaken grip strength, according to studies and medical experts. Cracking the neck, however, can be dangerous and may lead to serious injury.
Key Points
- Studies and medical experts say knuckle cracking does not cause osteoarthritis or lasting joint damage.
- The popping sound comes from bubbles forming and bursting in synovial fluid as joint pressure changes.
- Some people may crack joints for temporary relief, but excessive force can cause injury, especially in the neck.
- Cracking the neck is riskier than cracking knuckles because it can affect the spinal cord and arteries.
