What happens when you slow your breathing? By repeatedly stimulating the vagus nerve during those long exhalations, slow breathing may shift the nervous system towards that more restful state, resulting in positive changes like a lower heart rate and lower blood pressure.
Why does breathing out feel good? When you become stressed or anxious, your brain releases cortisol, the “stress hormone.” By taking deep breaths, your heart rate slows, more oxygen enters our blood stream and ultimately communicates with the brain to relax. Deep breathing also ups your endorphins, the “feel good” chemical.
What does slow breathing do to the brain? Research shows that deep breathing can have a direct effect on the overall activity level of the brain. What this means is that slow, deep breathing stimulates the vagus nerve, which runs from the brain to the abdomen and is in charge of turning off the “fight or flight” reflex.
