Ailment caused by the variations of time or season. For example: diseases caused by the vitiation of ''vata dosha'' manifest during the final stage of digestion of food (afternoon and post midnight), and diseases caused by vitiated ''kapha dosha'' manifest during time of intake of food, forenoon and pre-mid night and those caused by the vitiation of ''pitta dosha'' manifest during initial stage of digestion, noon and midnight. The vitiation of three ''doshas'' during the three different stages of life are responsible for manifestation of diseases- ''kaphaja'' diseases during young age, ''pittaja'' diseases during the middle age and ''vataja'' diseases during old age (Ch. Sa. 1/111-112).
