Meaning
To stay quiet and inconspicuous in order to avoid trouble, criticism, or unwelcome attention while a difficult period passes. In British English a second sense, to put your head down and work hard, is also current. Informal; the avoidance sense dominates in all varieties, with the hard-work sense chiefly British. Regional use: General English.
Origin
The metaphor is a literal posture: head lowered so as not to be seen or struck, and the idiom dictionaries illustrate it naturally with army examples ('in the army you soon learn to keep your head down'). None of the standard references checked supplies a first-use date or a specific originating event, so any precise claim, for instance that it dates from the sniper era or a particular war, would be guesswork; the popular association with trench warfare is plausible for the phrase's currency but undocumented. The British work-hard sense likewise appears in the dictionaries without its own history, and Wiktionary warns against confusing the phrase with the British and Australian expression 'head down, bum up'.
