Single joint airbag

Can you get arthritis? Nowadays, people are very concerned about the topic, among which "arthritis caused by finger snapping" is the most widely circulated topic. First of all, experts point out that this habit is not good. Components are usually joint joints, joint airbags and joint fluids.

Joint fluid is like machine oil, nitrogen. When we squeeze it out, nitrogen will make a sound. Kaka works, it doesn't hurt, it doesn't itch, it sounds nothing, but if you don't have this, you won't find that your hands are getting bigger, sometimes accompanied by pain.

So, is this habit harmful to your health? What is the truth? Between the two bones of the finger, there will be something called cartilage, which contains a solution. The solution is similar to the lubricating oil in the car, providing nutrition for the surrounding cells and keeping the articular cartilage healthy, and contains gases such as nitrogen, carbon dioxide and oxygen. The finger movement process is to pull a small piece of cartilage of the joint and then return to its original position.

At present, the mainstream theory is that the sound of joints comes from the eruption of cartilage friction. However, in 20 15 years, after the experimenter could realize MRI, scholars came to a very strange conclusion: they found that the sound of fingers was not caused by the friction of cartilage, but by the sudden hollowness caused by the expansion of carbon dioxide gas.

Of course, people will make more appropriate and rigorous scientific experiments in the future. A study of 20 10 showed that X-ray examination of hands like fingers found no high risk related to arthritis. However, arthritis is a physiological pathology, and its physiological sounds are crisp, simple and painless, and arthritis is usually accompanied by pain. Generally speaking, joints need to be reset, but often such long-term compression will lead to various joint diseases. Sometimes you break your fingers. Over time, symptoms of arthritis and osteoporosis may appear. If you keep a posture for a long time and then suddenly move your joints, it will make a sound.
