Snapping Fingers Can Cause Joint Wear And Tear

Cracking or snapping the fingers is a very common habit that usually generates a sensation of pleasure among some people who do this practice. However, this can cause wear and tear on the joints by increasing the leakage of the synovial fluid that protects them.

Its consequences have been warned for some years, although there is no consensus on its consequences. However, this research published in The Journal of the American Board of Family Medicine  found that cracking your knuckles does not appear to be a risk factor for osteoarthritis.

Why is finger snapping harmful?

The sound that we can hear after “snapping” our fingers is produced by the bubbles that we have in the synovial fluid that lines the joints. In this sense, the main function of the synovial fluid is to lubricate the bones so that they do not wear out with mutual friction.

In order for the knuckles to produce that particular sound, they must be forced into a position where the bones are as far apart as possible. After achieving this, it increases the volume of the synovial capsule and, as a consequence, reduces the pressure inside it.

It is then that the little bubbles burst and create that crunch so pleasant for many and so uncomfortable for others. The problem is not that the bubbles burst, but that unnecessary wear is generated that can be irreversible.

The experts of the Professional College of Physiotherapists warn that, sometimes, they themselves cause these clicks during check-ups or therapies. However, they try to do it under controlled conditions so that they do not generate negative impacts on health.

Likewise, they recommend checking as soon as possible if the creaking in the joints occurs on a daily or very common basis, because they can be a clear sign of a bone or muscle imbalance.

At the moment, as already noted, there is no conclusive evidence to ensure that this habit causes chronic disorders such as arthritis or osteoarthritis.

Some people, however, do say that there is an association with soft tissue injuries and decreased strength to hold certain elements, but this Harvard Health article points out that this habit of cracking the knuckles cannot be related to arthritis nor with any other type of joint problem.

However, physiotherapists advise not to do it constantly and to try to adopt measures to reinforce joint care.

Snapping your fingers: how to take care of joint health?

The College of Physiotherapists of Madrid advises to follow the following recommendations.

Improve diet

To strengthen bones, joints and muscles, it is advisable to include some source of calcium, protein and vitamins A, C and D. in the daily diet.

This study published in the Journal of Osteoporosis and Mineral Metabolism  shows that calcium is essential to prevent bone fractures and osteoporosis, and that vitamin D is essential for the absorption of calcium and its good distribution in the bones and blood .

• Dairy is one of the greatest sources of calcium, but so are broccoli, cabbage, and some types of fish.
• Protein should come from high-quality foods, such as lean meats, nuts, or eggs.
• Essential vitamins and minerals can be absorbed from fruits, vegetables, and whole grains.

Do exercise

Physical activity is one of the best ways to keep your joints healthy. Exercise makes it possible to strengthen them and prevent their long-term deterioration.

Its intensity must be controlled by a professional, as not everyone can undergo demanding workouts. By gaining muscle tone, you help prevent stiffness, pain, and other symptoms caused by tension.

Avoid being overweight

People who are overweight and obese are at the highest risk for joint disease. This is because  excess weight  accelerates the wear of cartilage and bones, as this publication of the Journal of Endocrinology and Nutrition points out .

It should be remembered that it is not convenient to carry objects beyond one’s possibilities, and a good posture must be maintained.

Does snapping your fingers really lead to joint problems?

As has been pointed out throughout the article, there is no scientific evidence to show that snapping or cracking your fingers is related to joint problems. However, as recommended by physiotherapists, it is advisable not to do so and lead a healthy life to help strengthen bones, joints and muscles.
