Answer

It depends on the context but we usually say for it,
1. 頭を空っぽにする （あたま　を　からっぽ　にする）
2. 頭をスッキリさせる （あたま　を　すっきり　させる）
3. 雑念を払う （ざつねん　を　はらう）

Answer

I agree Akiko's answer.
And we often use words, "refresh（リフレッシュ）" or "reset(リセット)" or "気分転換（きぶんてんかん）".
We use "気分転換（きぶんてんかん）" is changing or forgeting bad mind or things.
