Does clicking your fingers increase your chances of getting arthritis?
No. Rheumatoid arthritis, which is the kind that more commonly affects the hands and fingers, is a disease where your own immune system incorrectly begins attacking the cartilage of your joints. There’s no evidence that this is affected by how much repetitive movement you do, whether it’s finger clicking, typing or cracking your knuckles. Osteoarthritis is partly caused by mechanical stress of the joints but it normally requires a specific injury or a lifetime of hard work or obesity to do enough damage to trigger arthritis. No one clicks their fingers anywhere near enough to damage their joints like that, but it’s still best not to overdo it.
