The Science of shudh™

In the Shudh™ method, rapid drinking helps produce a rapid result. A 16-ounce volume of salted water consumed in one to two minutes reliably initiates gastric emptying within 8 to 18 minutes. The lukewarm temperature causes gastric receptive relaxation, easing the consumption of a larger volume of the solution. The bolus (rapid drinking) of solution moving through the system stimulates the gastro-colic reflex and has a "flushing" effect, which helps account for this method's superior thoroughness*.

Deep, controlled breathing, which is so central to yoga, also affects the gastric contents by moving the diaphragm. Internal scans show a marked elongation of the stomach during exhalation and a shortening during inhalation. At the same time, the five exercises in shankh prakshalana increase gastric motility to move the gastric contents along. The steady repetition of posture changes, together with controlled breathing, produces a "pumping" effect in the system.*

Yogic methods have been perfected by practitioners over thousands of years. With more rigorous investigation, Yoga's benefits are becoming even better understood.

Modern biomedical research has identified more of the mechanisms by which mind and body interact. Advanced practitioners of yoga can regulate autonomic functions, including heart rate and respiration. For the relaxed mind in a relaxed body, thinking “clean” may play a role in physically becoming so.
