Deep belly breathing optimizes oxygen and cognitive function

Breathing is the most critical bodily function — you die within minutes without oxygen, compared to days without water or weeks without food. Yet most people breathe unconsciously and inefficiently, taking shallow chest breaths rather than deep diaphragmatic ones. Breathe deeply into your belly the way babies naturally do. Take slow deep breaths down to your diaphragm, because most blood vessels in the lungs sit in the lower portions — deep breathing optimizes oxygen absorption in a way that chest breathing simply cannot match. Dr. Andrew Weil has said if he could recommend one thing to improve health and vitality, it would be learning to breathe properly. This is a high-leverage intervention hiding in plain sight.

    Breathe Into Your Belly Not Your Chest

    Breathe deeply into your belly like babies naturally do, rather than shallow breathing in your chest. Take slow deep breaths down to your diaphragm. Most blood vessels in the lungs are in the lower parts, so deep breathing optimizes oxygen absorption better than chest breathing.
