身心健康

Reads literally as 'body-mind healthy.' 身心 ('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 ('physically and mentally exhausted'), 身心愉悦 ('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 ('wishing you health in body and mind') is a standard well-wish, especially for elders.
