Well, between your joints, you have something called synovial fluid, which is basically there to keep you nice and lubricated, honey.

在你的關節之間 你有一種叫做滑膜液的東西 基本上是為了讓你保持良好的潤滑狀態，親愛的。

But every time you crack your knuckles, you're essentially pulling the bones away from each other.

但每次你敲開指關節，基本上都是在拉開骨頭之間的距離。

And as a result, the space between them gets bigger.

是以，他們之間的空間就會變大。

And so the synovial fluid, which is the same amount of fluid, has to go into a low pressure zone.

於是，同樣量的滑膜液，要進入低壓區。

And so any gas in it gets pulled out, forms a bubble and pops.

所以裡面的任何氣體都會被拉出來，形成一個氣泡，然後爆開。

And that is the noise that you're hearing now.

這就是你現在聽到的噪音。

Is it bad for you?

對你有害嗎？

It probably isn't bad for you, though Some studies have shown that it decreases grip strength over time.

它可能對你並不壞，雖然一些研究表明，隨著時間的推移，它會降低握力。

But the biggest risk seems to be that the more you do it, the more you annoy everyone around you.

但最大的風險似乎是，你越是這樣做，就越會惹惱周圍的人。
