Digestion and physical activities are associated with large and sometimes opposite changes in several physiological parameters. Gastric acid secretion during digestion causes increased levels of plasma bicarbonate ([HCO-3] (pl)), whereas activity leads to a metabolic acidosis with increased lactate and decrease in plasma bicarbonate. Thus naturally to keep digestion of ''sneha'' at optimum, person needs to avoid excess physical exertion.

Emotions affect physiological processes and actions which are responsible for nutrient malabsorption and digestive health. Saliva becomes more acidic under stress, depression and negative emotions due to alteration in salivary digestive enzyme, ptyaline. The negative emotions also affect the production of pepsin in the stomach, enzyme release from the pancreas and also liver bile flow.   Anxiety, is responsible for "fight or flight" response, that takes up a lot of brain's resources, so to compensate it slows down parts of brain that are not as necessary, such as the muscles involved in digestion. Anxiety can also cause low serotonin, and that means that some of the messengers that are normally travelling into body are possibly being created at a lower rate, leading to digestive disorders. During the fight or flight response, body creates massive amounts of adrenaline to give extra energy. In order to create that energy, adrenaline needs to take it from "sugar storage" - While adrenaline does this, body starts processing nutrients at rates that aren't ideal. It changes how body processes nutrients as well and could conceivably affect digestive health.  All these factors collectively may cause adverse effects of sneha due to impaired digestive power. Therefore, avoiding negative emotions is important in oleation therapy.

Bowel habits and duration of oleation therapy [verse 65-69]

==== Bowel habits and duration of oleation therapy [verse 65-69] ====
Koshtha i.e. bowel habits are the outcome of dosha dominance in bowel. vata, pitta and kapha dominance causes krura (hard), mridu (soft) and madhyam (moderate) koshtha (bowel habit) respectively. vata due to its ruksha (dry) (As. Hri. Su. 1/ 11 ) properties causes fast absorption of sneha and also requires large doses and longer duration for complete oleation. pitta has natural unctuousness associated with it due to its ushna (hot), sara (easy for dispertion), and drava (liquid) (AH. Su. 1/ 11) properties. These properties aid in the flow of sneha across all body parts and hence, an early push of dosha towards the bowel requires least dose and minimum duration. kapha has similar properties as sneha. However, the bowel habit in a kapha person is moderate due to its sthira (stable) and sticky properties. (AH. Su. 1/ 12). Modern science also explains bowel habits, its effects and considers intestinal transit time responsible for it. 40-45 hours is the normal bowel or in Ayurvedic terminology madhyama koshtha person’s intestinal transit time.  If it stays in the gut for longer than that, fluid is re-absorbed into the body and the stool becomes harder and dryer.. Body secretes about eight liters of fluid during the course of a day —from the stomach, salivary glands and pancreas—to decompose food and push it through the digestive system. But if food passes through too quickly, there isn’t enough time for all of that liquid to get absorbed, and the stool emerges in a semi-solid or liquid state. Thus, it is the physiological differences based on intestinal transit time that decide the duration of oleation therapy. The nature of a food item or a drug ingested affects bowel movement and explains the differences mentioned above.

''Koshtha'' i.e. bowel habits are the outcome of ''dosha'' dominance in bowel. ''Vata, pitta'' and ''kapha'' dominance causes ''krura'' (hard), ''mridu'' (soft) and ''madhyam'' (moderate) ''koshtha'' (bowel habit) respectively. ''Vata'' due to its ''ruksha'' (dry) (As. Hri.

Excessive thirst is a result of impaired digestion and absorption of lipids. Alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid) are essential fatty acids supplied by almost all polyunsaturated fats.  But any defect in their absorption may cause deficiency leading to excessive thirst and dry skin, brittle hair &nails, sleep and attention problems.
