I practice breathing for 18 years and I put the question: Why is deep breathing good for you?
Deep breathing and normal breathing are worlds apart. While normal breathing happens autonomously and most of the time unconsciously, deep breathing must be forced to happen. How can you relax to reduce stress by forcing the breathing? In my seminars on breathing movements and strategies that cover philosophical and psychological aspects of breath, deep breathing is not forced but gently activated, in a way controlled.
Gently activating breathing is crucial and effective element which you’ll experience in the breathing exercises that follow. But before we begin, let’s start with some facts and numbers about breathing, to better visualize the structure of the exercises and connect to deep breathing easier.
The adult’s normal breathing (tidal volume) is about ½ liter of air and that is only about 10% of the total lung capacity (TLC) which is some 5 ½ – 6 liters of air. That means that, there is about ten times more volume in the lungs which can be activated through deep breathing.
The fact that we have the tenfold capacity of air in our lungs brings us to the idea and purpose of deep breathing. We apply deep breathing technique because we want to reach the vital capacity of the lungs. The vital capacity (VC) is the sum of the expiration reserve volume (ERC) + tidal volume (TV) + inspirational reserve volume (IRV) as shown on the picture below:
