Will the knuckles make a "click" sound, and will the joints become inflamed?

Scratching one's head, biting one's fingernails and breaking one's knuckles are small habits for many people to relieve tension or anxiety.

This kind of little action often makes us feel relaxed, but some people say that breaking the knuckles will damage the joints. Is it true? How did the noise of "Ka La Ka La" come from?

A study published in the Journal of American Family Medicine Committee found that snapping fingers is not necessarily related to arthritis after investigating 2 15 middle-aged and elderly people aged 50 to 89.

There is also an informal study, which is very interesting. A doctor breaks the knuckles of his left hand every day, but his right hand never breaks. He persisted for 60 years. Finally, he found that there was no arthritis in both hands and won the Ig Nobel Prize in Medicine.

In fact, when you break a joint, the joint will be stretched and bubbles, mainly carbon dioxide, will be formed in the synovial fluid. These bubbles will flow in the joint cavity, and when the dissolved gas leaves the solution, it will form a cracking sound that we can hear.

Although many people think that this action will damage our finger joints, there is no conclusive evidence to prove this statement. As long as it is not too hard, it will not cause joint damage.
