Doctors debunked the myth of finger crunching: what are the consequences
Often, we or our friends crunch our fingers without even noticing it. Usually, we hear that this has a very bad effect on joint health and leads to arthritis. However, medical science refutes this fact and emphasizes that this process does not cause any significant harm.
Surprisingly, such a simple thing as finger cracking has been the subject of many scientific studies. Robert H. Schmerling, MD, a former practicing rheumatologist, describes their results on the Harward Health Publishing electronic resource.
Many people have the habit of cracking their fingers from time to time, and it is explained by their ability to calm down or relieve tension in this way.
The cracking of the joints occurs due to the distance between them, where gas bubbles in the joint fluid are ruptured during the cracking process. Since they need time to recover, it is impossible to break the same joint twice.
The doctor notes that finger cracking does not lead to harmful consequences, in rare cases it can only cause tendon damage.
In support of his words, the rheumatologist cites the experiment of Dr. Donald L. Unger from California, who regularly broke the bones of the fingers of one hand throughout his life, and by comparing X-rays of his hands, he made sure that arthritis progressed equally in both hands with age. A later study only confirmed his findings.
