How to say "health" in Japanese

Choosing the right word
  • 健康けんこうJLPT N3approx.Common
    nounThe usual word for health as a state of physical and mental well-being; use it when talking about keeping healthy, one's health in general, or health as a concept.
    煙草たばこをすうことは健康けんこうに悪わるい。↗
    Smoking is bad for the health.
  • ヘルスCommon
    nounA loanword used mainly inside set expressions and service names; on its own it is seldom the word you want for 'health', and it can even suggest an adult-entertainment business.
  • 衛生えいせいJLPT N1approx.Common
    nounCovers health in the sense of hygiene and sanitation — clean conditions that prevent disease — rather than a person's state of health; think of hygienic practices and sanitary standards.
    彼かれは衛生えいせい監視員かんしいんである。↗
    He is a sanitary inspector.
  • 剛健ごうけんCommon
    na-adjective, nounReally a descriptive word meaning robust, vigorous, or virile; it can describe a sturdy constitution, but it is seldom the word you want when you simply mean 'health'.
    彼女かのじょは10マイル競争きょうそうを走はしるほど剛健ごうけんだった。↗
    She was strong enough to run a 10-mile race.
  • 具合ぐあいJLPT N4approx.Common
    nounRefers to a person's condition or state, especially of health at a given moment; the natural choice when asking after someone or saying that they are feeling unwell.
    彼かれはこの数年間すうねんかんずっと身体からだの具合ぐあいが良よくない。↗
    He has not been in good health for some years.

Use 健康 for health as a general state of well-being, 具合 for a person's current condition, 衛生 for hygiene and sanitation; 「ヘルス」 appears mostly in set loanword uses, and 剛健 means vigor rather than health.
