Is Cracking Knuckles a Bad Habit? Here is What Actually Happens!

Is cracking knuckles only bad habit? Are you in that category of people who constantly crack the knuckles? Or you are a person who cringe once you hear that sound? Maybe people often tell you how bad is this “activity” for you but you simply continue to do that.

Here’s what actually happens when you crack your knuckles:

Throughout the years our body changes. You may have noticed that your joints start to ache, your muscles start to cramp, and you hear ‘popping’ noises when you walk up and down stairs. If you regularly crack your knuckles, you probably enjoy feeling that stretch in your fingers, followed by the popping sound.

But do you actually know what happens to the body when you crack your knuckles?

Two bones at your joint, come together inside the body. There is connection between them and ligaments. There is little space between your bones in order to allow your fingers to bend. When you crack your knuckles, you pull apart the surfaces of the joint and stretch the bones apart. This brings down the pressure in the joint.


So what’s going on with that popping sound?

There is in fact a fluid inside your joints. It contains gases such as oxygen, carbon dioxide and nitrogen. When pressure decreases in the joint, these gasses are freed. The gas bubble that is released by cracking creates that loud popping sound you hear.

According to a famous radiologist at the University of California, Dr. Boutin, cracking your knuckles stretches out our joints. Did you ever notice better motion in your fingers right after cracking your knuckles? This happens because you are in fact calming down the pressure in the joints. Also, you allow your fingers to become more flexible.

Well, Is Cracking Knuckles Bad For Us?

No! Dr. Greg Kawchuk explains that people probably assume it’s a bad habit because of that noise we hear every time. There are no evidences to suggest that the “activity” of cracking knuckles can cause arthritis or inflammation. Studies have also shown that knuckle cracking doesn’t influence or increase joint degeneration.


So if you like this “activity” , go for it! There is nothing unhealthy about it.
