Breaking fingers is bad for our knuckles? Can we break up often?

Do you have such an experience? When I was a child, my classmates often competed with each other to break their fingers, and the click was always heard.

I really envy their wonderful bones, which has become a way to be cool, because whoever breaks the most will be particularly eye-catching and surrounded by a group of students for advice on martial arts.

I tried, too. It hurts suddenly, and then it feels comfortable. However, people who are afraid of pain on this day can't bear to do this to themselves after playing once or twice.

Now I'm really glad I didn't break my fingers all the time, otherwise my fingers must be very thick now, and every girl's family ... has to regret it.

What's wrong with bones or bones that make a sound when they break their knuckles?

Why is there a click when you snap your fingers?

Fingers click when they snap their fingers, because there are bubbles in the synovial fluid of joint cavity, which are called cavitation bubbles. When we are apart, the bubbles burst and make a sound.

In fact, our fingers are connected by many connectors, which are physiologically called joint cavities. Every joint of our fingers has a joint cavity.

The joint cavity is like a gear of a machine, and there is a little lubricating oil in it, which is called joint synovial fluid in physiology.

Joint synovial fluid can not only lubricate joints, but also protect them. When the joint is stretched or bent, there will be obvious gaps in the joint cavity, and the surrounding gas will expand into these gaps very quickly, causing the bubbles in the joint fluid to explode or rupture, thus making a crisp click sound. This process is called physiological snapping.

This is why we broke the joint for the first time, and it is difficult to make it ring for the second time immediately, because it takes a while for bubbles to accumulate in the joint.

When you snap your fingers, the nerves at the ends of capillaries around the joints will be stimulated, thus promoting local blood circulation and activating bones and muscles. After breaking, the joint will become more flexible and more conducive to activities than before.

So as long as you play properly, it is beneficial and harmless.

What harm will snapping your fingers often bring to our health?

1. Too frequent fractures may lead to arthritis.

Many people break their fingers, and the more they break them, the more addicted they become. They break their fingers many times a day.

Although moderate does not harm the joints, if the frequency is too high, the friction will increase greatly, and the chronic inflammation of the interphalangeal joints will gradually lead to interphalangeal arthritis.

2. The joints will get bigger.

Frequent snapping of fingers will lead to swelling and deformation of finger joints, because repeating this action will cause traction stimulation to ligaments and joint capsules, leading to exudation. If this happens for a long time, the appearance of finger joints will become larger or even deformed, and repeated stimulation will easily lead to hypertrophy of joint capsule and joint synovium.

3. Affect grip strength

Affect fingers to grasp things, unstable. This is a phenomenon that many people will appear. In the process of breaking your fingers constantly, or in the process of knocking on the keyboard for a long time, you will obviously feel unstable in grasping things. This phenomenon is mainly due to the change of hand grip strength, which leads to the phenomenon that you can't grasp things when holding them.
