n in Tibetan medicine, the purposeful adjustment of an individual's eating habits to autumn weather. Between the winter and the summer solstice, it is traditionally thought that, as the amount of energy exerted by the sun decreases, digestive processes associated with badahan and schara begin a transitional period to prepare themselves for the peak level of activity that occurs during the winter. During this time, these digestive functions become quite vulnerable to errors in dietary habits. As a rule, the selection of foods during meals becomes more and more limited. Individuals are encouraged to consume foods that are light with—in this specific order—predominantly sour, salty, astringent, and sweet taste. While the performance of the gastrointestinal tract progressively increases, it is best to avoid foods that are heavy, have a strong taste, and stimulate. The individual should consume meals frequently, but small quantities are encouraged so as to keep the digestive processes reasonably occupied. However, these processes should not become overwhelmed. Establishing a specific place and time for meals is a priority throughout autumn. See also schara and badahan.
