A large percentage of people like to pop their fingers for no inherent reason other than wanting to hear that addictive “pop”. But is the “pop” worth the price? This article examines if any of the rumors about potential health hazards from popping your knuckles are true as well as exactly why the “pop” happens.
University of Alberta scientists and researchers were determined to understand exactly how a finger “pop” happens and its health effects. To get an inside look they put a finger under an MRI and slowly pulled it until it cracked.
The result of their research was fascinating.
They discovered that the “pop” is not a result of anything popping at all, but rather a sound resulting from the rapid formation of a gas cavity. From friction and pressure, the gas forms inside of the lubrication surrounding the joint.
Here is a youtube video that demonstrates….
UA researchers did not find anything indicating that this gas formation has a negative effect on the joint, including arthritis, or general health in any way.
However, they do believe that more research directly related to health effects can be done. Until any research says otherwise feel free to crack away with ease.
