健康 (jiànkāng) — use 保健 (bǎojiàn) when referring to the practice of maintaining health, while 健康 (jiànkāng) refers to the state of being healthy.

Think of 保 (bǎo) as 'to protect' and 健 (jiàn) as 'healthy.' Visualize a shield (保) guarding a vibrant, healthy person (健), reminding you of the importance of health protection.

Be mindful of the context in which you use 保健, as it can be informal when referring to personal health practices but may also appear in formal healthcare discussions. Common collocations include '保健食品' (health supplements) and '保健知识' (health knowledge).

While 保健 may not appear specifically in HSK materials, it connects with health-related vocabulary found at various levels. Students should focus on the components of the term and related words, such as 健康 (healthy) and 医疗 (medical care).

In Chinese culture, there is a strong emphasis on preventive health measures, with practices like Traditional Chinese Medicine and regular health check-ups being commonplace, making 保健 a vital part of daily life.

Learners often confuse 保健 with 医疗 (yīliáo), which means 'medical treatment.' For example, saying '我去保健医生' (I go to the health protection doctor) is incorrect; it should be '我去看医生' (I go to see a doctor).
