Changes

The role of desha is significant in matters of health and disease. It denotes the habitat of an individual and is also considered among the Karana dravyas in Sutra Sthana Chapter 1. Desha influences the individual’s diet, etiological factors responsible for various diseases, availability of medicinal plants. In fact, extending the man-environment relationship, Ayurveda considers examination of one’s locale to be an important factor in the diagnosis of a disease. Ayurvedic texts classify desha into three types: anupa desha (marshy land), jangala desha (forested or wooded land), and sadharana desha (mix of marshy and forested land). (Kalpa Sthana, 1/6). The concept of oka satmya (adjustment or adapting to a particular diet or behavior due to habitual use or practice) is also closely related to desha and season. A diet or medication suitable to a particular region or time may be counterindicative in another.

===== ''Kala'' (temporal factors), and its role in Health and Disease =====

Kala plays a very important role in Ayurveda, and is a universal factor that affects the purusha and the loka. Vedic texts talk of various time spans, quite similar to those in modern sciences – describing the life-spans of the universe and various celestial objects, as well as that of the purusha. It is also a Karana dravya, per Ayurveda (Sutra Sthana, 1/48). In Ayurveda, Kala does not only mean time, but also seasons (ritu), and from that standpoint, plays an important role in determining causative factors of diseases or prescribing therapies for maintaining health.  (Sutra Sthana , 11/23, Vimana Sthana, 1/21/6, Sutra Sthana 6/4).

Kala also influences doshika rhythm. External environmental changes brought about by changes in the season influence the pattern of doshic changes in the body. These have been described to be of three stages: Chaya (or Sanchaya, accumulation), Prakopa (vitiation, aggravation), and Prashamana (remission to normalcy) (Sutra Sthana, 17/114). These stages generally occur in a natural manner through normal seasonal variations, and therefore Ayurvedic practitioners would typically advise care and adjustment in diet and lifestyle to account for these changes.
