Hey guys your probably here because you want to know all about cracking those knuckles
and joints and is it bad for you something we've been told since childhood well I'm gonna
answer that question along with many other questions in this weeks responding to your
comments where we look at fun questions we look at science based questions but most importantly
we always look at the evidence Jacob Levi My girlfriend cant stand me cracking my knuckles
and I want to know if its bad for me Jacob Levi thank you for your comment I like this
comment very much which is why I picked it and I guess youre wright some people really
dont like the sound of cracking joints or knuckles.
I have never really minded it maybe because I like to do it now and then but some people
have louder cracks than others thats an important fact to remember so lets begin with some science
firstly what is that cracking popping sound that you get in the joints and knuckles well
its basically nitrogen bubbles bursting in our cynoavial fluid now you may be thinking
what on earth is cynoavial fluid well if
you
dont
know what
it is cynoavial fluid basically helps lubricate our joints it
kind
of works in a similar way
to engine oil
