Myth 2: Cracking Your Knuckles Causes Arthritis.

False. Good news for knuckle-crackers — the pop you hear when you crack a knuckle doesn’t mean you’re putting wear and tear on those joints, Carter says. When you bend your finger to crack your knuckle, you put pressure on the fluid between your bones, and that releases a gas. “That’s what you hear: pop,” he says. Doing it won’t lead to arthritis, so you’re safe to crack away. #acten
