Many people crack their knuckles every once in a while, it’s a common habit which produces a sharp cracking or popping sound. Now, there are many varying opinions about the health effects of cracking your knuckles. For some people, it’s completely harmless and is probably a good habit, while some people claims that cracking knuckles leads to arthritis. But there’s no medical evidence to support that.
The real reason behind the ‘cracking’ sound when you crack your knuckles and it’s long term effect has been the topic of debate for many years in the scientific community.

“It’s a little bit like forming a vacuum. As the joint surfaces suddenly separate, there is no more fluid available to fill the increasing joint volume, so a cavity is created, and that event is what’s associated with the sound.” explained the study researcher Greg Kawchuk, a professor in the Faculty of Rehabilitation Medicine at the University of Alberta in Canada.
