Deep breathing, or diaphragmatic breathing, is a skill that many of us have lost. To know what it’s like to really breathe deeply, take a minute out and observe a baby and what happens when they breathe. Their whole belly rises and falls with each breath, rather than just the chest. Now have a look at how most adults breathe - you rarely see the belly moving much at all, and if it does, it’s usually just the upper portions, rather than the whole abdomen. But this is a skill that could be highly important to get back in touch with.
