Around us, we often see many male colleagues snapping their fingers, making a "clicking" sound. It makes us frown. In fact, the joints of our body can also make a "clicking" sound. Many of us have discovered this secret, but many people are puzzled by it. What is going on? The joints can make a sound. Is this a sign of illness?

Our finger joints often make a "clicking" sound. After the joints make a click, how long will it take for the next click to occur?

Experimental procedures

1. Pull a finger outward and the finger joint will make a sound.

2. Two minutes later, pull out the finger you just pulled out. Will it still make a sound?

4. You will find that after 10 to 20 minutes, when you pull that finger outward, the finger joint will make a sound again.

Scientific Secrets

When we squat down and stand up, we often hear a "clicking" sound from the knee joints. Why do our joints make noises? It turns out that the fluid around the joints contains dissolved gas. When the joints are straightened, the pressure on the liquid will be reduced, bubbles will come out, and the gas will make a noise when it comes out, just like the sound when you open the cap of a soda bottle. However, the gas and liquid in the human body are blocked by the skin and cannot be discharged from the body. Therefore, after 10 to 20 minutes, the gas will dissolve in the liquid again. At this time, when you straighten your finger joints again, it will make a noise again.

Apply what you learn

Be careful, some students like to squeeze their fingers, making them make a "click" sound, which they feel comfortable and they think can make the finger joints more flexible. In fact, there is no benefit in doing this often. On the contrary, it will loosen the finger joints and easily cause bruises. Therefore, it is best not to do this often.

Today we will reveal to you the reasons why there are noises in our body's joints. After reading the above, do you think it is clear at a glance? Have you discovered that our bodies are really amazing? However, the lifespan of each joint in the body is limited, so we still have to use them with caution.
