Dr. Shailinder Sodhi, an Ayurvedic and Naturopathic physician based in Bellevue, Washington demonstrates: Nadi Shudhi - Exhalation and an inhalation through the left nostril, followed by a full breath through the right, with the whole pattern repeated several times. It is highly effective in clearing emotional blocks and infusing energy) Sheetali Pranayama - The cooling breath is usually done after practicing other asanas and pranayamas. Sheetali Pranayama cools the body. Sheetali in sanskrit means ‘cooling’. Sheetali involves folding of the tongue to form a tube like shape. Some people may find it difficult to fold their tongue. They can do an alternate practice call Sheetkari Pranayama, which gives similar benefits. Breathing exercises are important because not enough carbon dioxide exchange is happening due to shallow breathing. This exercise is not only good for the lungs, but for the entire cardiovascular system.
