How does breathing differently have all of these great benefits? It can seem strange that we have so much potential in changing the way we breathe. Below, we’ll give you a quick introduction to the science of breathing and SOMA Breath.
When you breathe in, you inhale oxygen (O₂) (and other molecules and gases), when you breathe out, you exhale (CO₂) (and other molecules and gases). That’s respiration.
When you breathe in, your heart rate goes up a bit. When you breathe out, your heart rate goes down a bit (Lehrer, 2007). This is the basic principle of respiration, but it is also important for metabolism.
When you breathe in O₂, it binds to red blood cells from your lungs. Those blood cells transport the O₂ to tissue and organ cells thanks to the pumping action of your heart. The oxygen is needed by the mitochondria in the cells of your body as a means of energy, like a fire (“Cellular Respiration”, n. d.).
Imagine you have a fire burning inside of you that produces all the energy you need to live.
Too little oxygen, and a fire cannot burn at all. Just like in our bodies: too little oxygen and we can’t survive. Too much oxygen, and the fire will burn too much, potentially cause some damage. If our body has too much oxygen, it causes something called oxidative stress. Oxidative stress happens when there is an imbalance between free radicals and antioxidants in our body. It can lead to cell and tissue damage.
So it is clear that we need the right balance of oxygen; not too much and not too little.
O₂ + Glucose ⇨ ATP (energy) + CO₂+ H₂O
The oxygen you inhale is carried around your body by red blood cells and it combines with glucose in the mitochondria of your cells, which produces adenosine triphosphate (ATP) energy, carbon dioxide (CO₂), and water (H₂O). When you exhale, you breathe out the carbon dioxide and water. The ATP provides energy to your body, so it can function normally.
The autonomic nervous system is made up of the sympathetic nervous system and the parasympathetic nervous system. It regulates bodily functions like pupil dilation, heart rate, and saliva production.
Inhalation stimulates your sympathetic nervous system, exhalation stimulates the parasympathetic nervous system. By changing the way you breathe you can make one of them more dominant than the other in that moment depending on what you want (Russo et al., 2017).
Rapid breathing and taking in more oxygen than normal energises your body. It will also cause contraction in the body as you breathe out carbon dioxide at a faster rate, stimulating the sympathetic nervous system.
Slowing down your breathing and extending your exhale to be longer than your inhale will have a relaxing effect on the body. It causes an increase in carbon dioxide levels and also stimulates the production of nitric oxide, which dilates blood vessels (vasodilation). Vasodilation reduces blood pressure and increases blood flow (Russo et al., 2017).
