hitāyu / hitāyuḥ: what the term means and how it is translated
hitāyu / hitāyuḥ हितायुः is an Ayurvedic technical term. It is rendered into English in 4 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

How it is translated, and whether the translation holds
Each rendering is given with the source that uses it. The assessment is ours.
Salutary life
WHO international standard terminologies on Ayurveda (WHO, 2022) · Term ID ITA-1.2.2, printed p. 2 · standard
WHO's description: 'A mode of life that is advantageous for oneself and generally beneficial.' Recorded as a fact about WHO. Note WHO reads hitāyu as a mode of life, i.e. a way of living, which is a reading of Su 30.24's long list of conduct rather than of Su 1.41's bare adjective.

beneficial
Charaka Samhita, tr. Avinash Chandra Kaviratna (1896-1913) · Sutrasthana Lesson XXX, aphorism 20 · translation
Public domain. Kaviratna's phrasing is 'the Life is said to be beneficial', so his English term is 'beneficial Life'. He does not use 'salutary'.
Good
Charaka Samhita, tr. Avinash Chandra Kaviratna (1896-1913) · Sutrasthana Lesson I, aphorism 40 (= Su 1.41 modern): 'Good, evil, happy and unhappy is Life.' · translation
The same translator renders the same word two different ways in two places - 'Good' in Su 1.41 and 'beneficial' in Su 30.24. A real internal inconsistency in the only quotable English Charaka, and worth recording as such.
wholesome life / useful life / life in harmony with self and surroundings
common Indian journal and textbook usage · textbook · our paraphrase of the source, not its words
Circulates widely; 'useful life' and 'life in harmony with the surroundings' appear in Indian journal abstracts. None of these is anchored to a single Sanskrit word in the source verse.

Defines hitam āyuḥ by a list of ethical and cognitive conduct - benevolence, abstention from others' property, truthfulness, tranquillity, deliberate action, vigilance, balanced pursuit of the trivarga, reverence, control of passions, giving, austerity and knowledge, attention to this world and the next, good memory - and then defines ahitam simply as the reverse. This excerpt is the hitāyu/ahitāyu portion of the verse; the sukha/asukha portion precedes it in the same verse.
Charaka SamhitaSutrasthana Lesson XXX (Arthedaśamahāmūlīya):20 in Kaviratna's numbering · checked against the source
Of one who seeks the good of all creatures, who abstains from appropriating what belongs to others, who is truthful in speech, who is devoted to tranquillity, who acts only after reflection and exami¬ nation, who is never heedless, who pursues the aggregate of three (/. e., Religion, Wealth, and Pleasure) without any one of them afflicting the others, who worships with reverence all those that deserve worship, who derives praise from knowledge and science, who waite with reverence on the old, who has properly controlled the impulses of affection or attachment, of jealousy, of arrogance, and of pride, who always makes diverse kinds of gifts, who is devoted to penances, knowledge, and peace, who is conversant with topics connected with the Soul, who is devoted to That, who acts in view of both this world and the next, and who has a good memory, the Life is said to be beneficial.
The lawfully quotable English of the hitāyu definition, item-for-item matching the Sanskrit of Su 30.24 above. Kaviratna prints this as aphorism 20 of his Lesson XXX; the modern vulgate prints the whole fourfold definition as a single verse 24. Hyphenation artefacts and 'waite' for 'waits' are OCR; reproduced as retrieved.

हिताहितं सुखं दुःखमायुस्तस्य हिताहितम्| मानं च तच्च यत्रोक्तमायुर्वेदः स उच्यते||४१||
The first occurrence of the hita/ahita pair as a division of āyu, here as a bare dvandva (hitāhitaṃ) with no content; the content comes only at Su 30.24. Note the same verse also says āyurveda declares what is hita and ahita TO life (tasya hitāhitam) - a second, different use of the same pair in one line.
Not to be confused with
- sukhāyu
- The pair that the tradition itself insists is not the same. Sukhāyu is defined by health, youth, strength, wealth and the ability to do as one pleases (Su 30.24, first half); hitāyu by ethical conduct and cognition. A person can have one without the other, which is the whole point of the fourfold division.
- svastha
- Svastha is a state of the body-mind system defined by doṣa-agni-dhātu-mala balance and pleasant ātman/indriya/manas (Su.Su 15.41). Hitāyu is a manner of living. Health is a precondition described in sukhāyu, not in hitāyu.
- pathya
- Pathya is what is suitable for the channels/for a given patient in a given condition - a dietetic and therapeutic judgement. Hita in hitāyu is an ethical and social judgement about a life as a whole.
- hita (as in tasya hitāhitam)
- Su 1.41 uses hita twice in one verse: once as a kind of life, once as what is beneficial to life. They are not the same use and conflating them collapses a distinction Charaka draws in a single line.
Renderings that do not hold
- healthy life. Health belongs to the sukhāyu description in Su 30.24 ('not afflicted by any disease physical or mental'), not to hitāyu. Rendering hitāyu as healthy life imports the wrong half of the verse.
- happy life. That is sukhāyu. The two are explicitly separate limbs of the same definition.
- long life. Duration is not mentioned in the hitāyu definition at all.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Whether any classical commentator (Chakrapani on Su 30.24) makes explicit the now-common teaching that sukhāyu is immediate pleasure while hitāyu is beneficial in the long run and for society. That formulation appears on carakasamhitaonline.com's discussion, which is a modern editorial layer, not the mūla; I did not retrieve Chakrapani's Sanskrit on this verse.
- Whether NAMASTE codes hitāyu, and whether it follows WHO's 'salutary life'.
