More than just stretching
Yoga affects the central nervous system (CNS) by shifting it from a "fight-or-flight" (sympathetic) state to a "rest-and-digest" (parasympathetic) state, reducing cortisol while increasing GABA, serotonin, and dopamine. Regular practice could enhance brain structure and function
Possible Key Effects on the Nervous System:
Autonomic Nervous System Regulation: Yoga increases parasympathetic nervous system activity, which lowers heart rate, lowers blood pressure, and promotes a calm state.
Brain Structure and Function: Studies show that regular yoga, particularly Hatha, can increase the volume of the hippocampus and enhance cognitive functions like memory, attention, and awareness.
Neurotransmitter Modulation: Yoga boosts mood-enhancing neurotransmitters, including GABA (which reduces anxiety), serotonin, and dopamine.
Vagus Nerve Stimulation: Techniques used in yoga, such as deep breathing and specific poses (e.g., Child's Pose), stimulate the vagus nerve, which runs from the brain to the gut, impacting heart rate and stress reduction.
Reduced Neuroinflammation: Consistent practice is associated with lower levels of chronic stress and inflammation in the brain.
Neural Plasticity: Yoga stimulates the mTOR pathway, promoting the creation of new nerve connections and overall brain plasticity.
These changes may foster increased resilience to stress, improved cognitive abilities, and enhanced emotional regulation
