‘宽心’ literally means ‘broaden the heart’ — combining 宽 (kuān, ‘broad, relaxed’) and 心 (xīn, ‘heart, mind’). It expresses the idea of easing mental tension, letting go of worry, or calming oneself emotionally. Unlike a physical action, it’s an internal shift toward emotional relief and composure.

This word is commonly used in comforting speech — especially when someone is anxious, stressed, or overly concerned about a situation. It often appears in spoken Chinese as gentle advice or reassurance, such as from elders to younger family members or doctors to patients. While not formal in academic writing, it’s warmly idiomatic in daily conversation and carries a soothing, empathetic tone.
