  • Nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin. Some responses are reflexes and happen without conscious decision
24
Q

How breathing effects the autonomic nervous system

A
  • Breathe helps regulate the involuntary response
  • Abnormal breathing can overstimulate the sympathetic system
  • Regulated breathing can moderate the intensity of a pose or situation.
  • Breathing is the tool we use in yoga and outside of yoga.
  • Slowing our breath down, facilitating, controlling our breath
  • If we can teach our students how to move with breath as the most important. If they can channel the breath to the movement, they will find the balance between the sympathetic and parasympathetic
