When we press our knuckles with our hands, we will hear a click sound. Why do knuckles click?

In our daily life, we can always hear the sound of fingers giggling, which is likely to happen at work or in class. In short, we can often see. It can also be seen from many movie plots that people who practice kung fu will snap their fingers before the big contest, just like starting before the big contest. Many people are particularly interested in snapping their fingers, and they will study it and get used to it gradually. They will snap their fingers inadvertently until they hear a giggle. After a period of finger amputation, some people have scruples, fearing that frequent finger amputation will lead to injury. Whether it is harmful or not needs further study.

Often break your fingers and giggle, will it hurt?

We can first grasp why there is a giggle after a broken finger. Everyone has many tendons and fingers in his body, which can connect the muscles and joints of the whole body. Tendons are connected with the muscles of joints, and there is an inevitable thing, that is, lubricating fluid, which can be mastered by fingers and joints. In the case of snapping fingers, the tendon is bound to be hard, the sliding friction will expand, the burden of wetting will also increase, and steam will be generated in the joint capsule. When the working pressure reaches a certain level, it will explode, just like playing a balloon. After the expansion of standard air pressure explodes, there will be sound. The same is true after the finger is broken.

It can be seen that it is a natural physiological phenomenon to make a sound after fingers snap, which is also called physiological snapping. It's normal. Don't worry about harm to your health. But it must be reminded that, of course, physiological phenomena only occur sometimes, and we also need to watch the clicking sound. I think if there are abnormal changes, we should pay attention to joint injury. Sometimes snapping your fingers is not very harmful.

What kind of bell should be paid attention to?

It can be recognized from the snapping sound, and the general physiological snapping sound will be crisp and there is no other noise. If the snapping sound is low, continuous sound appears, and it is mixed with other remixes, you need to pay attention to it, and it is mostly damaged in joints or other parts. In addition to noise, we can also see whether there is pain when the clasp appears, and it lasts for a long time. Whether there is inflammation around the snapping sound, and whether the theme activity is still flexible.

When pain, swelling and subject activity are restricted, don't ignore it. Nine times out of ten, there is something wrong with the joints or the body. You should search for the cause as soon as possible, lest the situation get worse.

There are many joints in the body that can produce physiological snap, not just fingers, neck and toes. Sometimes you don't have to worry too much about giggling. Most of them are normal physiological sudden sounds. If the above situation occurs, you can't ignore it. The sooner we find out the reason, the better for our health. Advise people who usually like to break their fingers not to break them too often. Accumulate over a long period will lead to injury, do not want to have problems, or try to control yourself.
