身心健康

Reads literally as 'body-mind healthy.' 身心 (shēnxīn, 'body and mind') is the Chinese equivalent of English 'mind and body' — note the order is reversed. 身心 alone is also common: 身心疲惫 (shēnxīn píbèi, 'physically and mentally exhausted'), 身心愉悦 (shēnxīn yúyuè, 'physically and mentally pleased').

A go-to four-character phrase in health writing, parenting articles, and HR wellness materials. Functions as both noun ('your physical and mental health') and adjective ('be physically and mentally healthy'): 祝你身心健康 (zhù nǐ shēnxīn jiànkāng, 'wishing you health in body and mind') is a standard well-wish, especially for elders.
