Crack Your Knuckles, It Doesn’t Lead To Arthritis
There’s zero scientific evidence that cracking your knuckles is bad for you, or that it leads to arthritis. The worst thing cracking your knuckles can do is annoy the people around you. When we crack our knuckles, we’re popping the synovial fluid, which is the fluid that helps us lubricate our joints. The worst thing that could happen is that you lose your grip strength over time. It also feels good to crack our knuckles, almost like a release of pain that’s built up over time. So crack away, and you won’t suddenly develop arthritis (Wanna Be A Viking).
