A consistent factor amongst the breathing techniques in the studies cited above is that they all encourage diaphragmatic breathing. Often referred to as “belly breathing”, diaphragmatic breathing allows the lower belly to expand and contract with each cycle of breath. As we all know, allowing full expansion of the stomach is habitually avoided in today’s society.
However, when the abdomen is able to relax and expand fully on the in-breath, the lowest part of the lungs can be filled with oxygenated air. Without this full inhalation, you may be left feeling anxious and short of breath. Likewise, when the abdomen can contract inwards fully with the out-breath, the carbon dioxide is completely exhaled from the lungs, and breathing slows down.
This slower, more relaxed way of breathing results in a more peaceful body and state of mind. Thus, slowing down your breathing with deep breathing exercises can help you, whether you’re preparing to give an important presentation or want to fall asleep more quickly.
