It is a habit many people have: snapping their fingers. Some love to do it, while others find it horrible to hear. Finger snapping is a fascinating phenomenon that is still not fully understood. What actually happens in your fingers when you snap them? And is it really as bad for you as people claim? We explain it to you!
What causes the snapping sound in your fingers?
Between joints is a special fluid that acts as a lubricant for your joints and allows you to move smoothly. Pulling or bending your fingers creates more space for the fluid and this can then create gas bubbles. When the bubbles then "pop", you get that characteristic "snap" sound. So the sound does not come from your bones, as many people think.

Snapping fingers is harmful: fable vs. fact
Although some people claim that snapping your fingers can lead to osteoarthritis or arthritis, there is no scientific evidence to support this claim. Indeed, there are several studies themselves showing that there is no link between finger snapping and the development of osteoarthritis.
So while snapping fingers does not seem to cause physical harm, it can be a bad habit to have. It can disturb others and it can also be a sign of nervousness or restlessness. If you find that you often snap your fingers, it may be worth trying to break this habit. Think carefully for yourself where the craving comes from and see if you can do something about it.
