Abstract

Review: Can Yoga Breathing Exercises Improve Glycemic Response and Insulin Sensitivity?

Ted Wilson, Kevin L Kelly and Sarah E Baker

This is the first review of the literature on the effects of slow breathing on glycemic regulation and insulin sensitivity. While many studies have investigated the effects of yoga on individuals with diabetes, few studies have specifically focusing on the isolation of slow breathing as the principle factor in their intervention. While it is difficult to separate the exercise-related effects of yoga, there is considerable evidence that a breathing intervention is capable of increasing insulin sensitivity and improving glycemic regulation. This appears to be true both acutely and chronically in healthy individuals and those with diabetes. Yoga pranayama and the slow breathing practices that are fundamental to yoga represent a relatively low-cost and under-utilized intervention for individuals with conditions related to altered glycemic regulation and insulin sensitivity. More studies should focus on pranayama and slow breathing maneuvers to better clarify the role of respiratory modulation on glucose metabolism and insulin response.
