Meaning
To take a major risk without worrying about the possible consequences.
It’s used both approvingly, to praise boldness, and critically, to describe reckless disregard for danger.
Origin
The image is of physically throwing something into the wind so that it is carried off and lost — in this case, “caution” itself, discarded like ballast or unwanted cargo rather than kept close for safety. The exact origins of the specific wording are not well documented in standard references, but the underlying metaphor of casting aside restraint “to the wind” or “to the winds” appears to be a natural extension of much older English idioms that use wind as a symbol of something scattered, lost, or blown away beyond recovery (compare “scatter to the four winds”).
