📜 Origin Story
This expression has a fascinating history tied to freedom. In olden times, prisoners or soldiers were often shackled by the legs with 'grilletes' (shackles) when they slept to prevent them from escaping. To be able to 'dormir a pierna suelta'—to sleep with a 'loose leg'—meant you were free from these restraints. This freedom from physical bonds came to represent a freedom from worries, allowing for a deep, peaceful, and untroubled sleep.
