休息 (xiū xi) means 'to rest' — to pause from activity in order to recover energy, relax, or avoid fatigue. The character 休 combines the radicals for 'person' (亻) and 'tree' (木), evoking the image of a person leaning against a tree — a natural, peaceful pause. 息 means 'to breathe' or 'breath', suggesting quiet, calm respiration during rest. Together, they convey intentional, recuperative stillness rather than mere inactivity.

This word is commonly used in daily life: taking a break at work, resting after exercise, or recovering from illness. It can be used as a verb ('I need to rest'), a noun ('a short rest'), or in imperative phrases ('Rest now!'). Unlike 睡觉 (shuì jiào, 'to sleep'), 休息 doesn’t require falling asleep — it includes sitting quietly, lying down with eyes closed, or even light stretching. It’s neutral in register and appropriate in both casual and formal contexts, such as workplace announcements or doctor’s advice.
