Finger tapping: Is this habit hurting you? Science has an answer
Snapping fingers

Finger snapping: almost everyone does it, and usually with a certain amount of enjoyment. But often, a moment after the characteristic stroke, we also wonder if this habit is harming us or not?

If, more precisely, by manipulating the fingers (knee joints, elbow joints, wrists or even the neck) we understand whether we have arthritis or not? Is there a scientific answer to this dilemma?

Our knuckles are immersed in a fluid called synovial fluid, which is meant to nourish the tissues and lubricate the joints.

When we move our fingers, the liquid releases gaseous compounds that fill the empty space in the joint, forming small bubbles.

When we snap our fingers, the pressure in the liquid suddenly drops and the air bubbles burst, creating a multitude of smaller bubbles, which then take a significant amount of time to recompose. For this reason it is necessary to wait before the phenomenon is repeated.

Science has tackled the issue of joint noises a bit to understand if the habit of cracking your fingers can lead to arthritis problems.

In 1990, a study appeared in the Annals of Rheumatic Diseases explaining how, more than osteoarthritis, finger cracking can cause hand swelling and a general decrease in hand grip strength. But, apart from these contraindications, the study on finger snapping does not cause harm or benefit.

A Californian doctor, Donald Unger, also dealt with this topic, trying to investigate this phenomenon: for sixty years he cracked the fingers of one hand, leaving the other in peace. Well, comparing the effects on the hands, he concluded that straining the fingers to hear the noise has no effect, does not increase the risk of developing arthritis.

Of course, Unger's study had a lot of scientific value, so much so that it won him the Ig Nobel Prize in 2009. In any case, he has dispelled the myth of arthritis associated with finger cracking.
