“Cracking your knuckles causes arthritis.”
TL;DR ·Decades of research and comparative studies show no link between knuckle cracking and arthritis.
Decades of clinical research and comparative studies consistently demonstrate that cracking your knuckles does not cause arthritis . A study of 300 individuals found no increased preponderance of arthritis in habitual knuckle crackers compared to those who do not crack their joints . The popping sound is actually caused by negative pressure or gas bubbles forming and bursting within the synovial fluid of the joint . Medical experts emphasize that there is no scientific basis for this claim and label it a common medical myth . While the habit is not linked to arthritis, some research suggests habitual cracking may lead to reduced grip strength or hand swelling . One longitudinal experiment involving a subject cracking knuckles on only one hand for 50 years also found no difference in joint health between the two hands .
