What happens with cracking knucles

Cracking knucles , stretching body,belly cracking and neck driving keeps relief , isn’t it?

Some people does this kind of activity not only for relief but their habit of doing this. They don’t detect it but have a habit of doing it continously .

It seems normal for us but Dr. Donald Unjar from California has done his research for 60 years in this issue.How did he did a research till 60 years may be a arising question.

Donald used to crack his knucles from one hand and do not this kind of crack in another hand for 60 years. Then , he used to go for examination of both hand every month.

From 60 years research , he find that no differences is seen in the both hand but after some years joints started to show light pain can be feel.

”According to his research, ‘Our body contains one kind of fluid in joints which is called as Sainovel .When we stretch our joints that time some air drops are created in the middle of that fuild. And again we close out our knucles then that air drop explode which makes the sound.’

If you had cracked your knucles once then wait for 20 minutes and only do for second time. But Donald says, ‘If you have a habit of craking knucles then try to avoid it slowly, It don’t show big reaction but will have some problem in joint .’

Donald has got Nobel Prize for this research.
