Crack me Not, How sound is produced during Cracking Hands?

One of our common habits we do while working in office, during playing, in school or anywhere else, we crack our fingers and toes to relief stress as we feel it make our bones light when we get tired of work.
One of the concepts is that cracking decrease pressure in the joint space or capsule, which are filled with a variety of gases mainly carbon dioxide.

The sound made is due to the lower pressure of gas then the surrounding fluid which rushes in and it takes 15 to 20 minutes to re-dissolve the gas then to produce the cracking sound again.


And it may be said that the sound is produced when the ligaments or tendons snap while moving over bony prominences surrounding the joint or the fluid containing the joint.

As we also heard from our elders that it weakens the bones and reduces the friction between joints.

But if we go over the theory then it is said that the energy produced during cracking is insufficient to damage cartilage cells. But a habitual knuckle cracking can cause damage to tissues and joints, lower grip strength, hand swelling, soft tissue damage in tendons.

Through the nature of this habit, we doesn't take it seriously as it occurs in our daily routine and we even intentionally do it, or it often happens by chance, but keep in mind excess of everything is bad.
