It helps regulate breathing, heart rate, digestion, metabolism, sleep, hormonal activity, sensory perception, balance, reflexes, mood, and much more. The nervous system ensures these signals are transmitted throughout the body, allowing all systems to function in coordination.
Because the brain and nervous system influence virtually every aspect of human function, disruptions to this network can affect movement, recovery, cognition, sleep, and overall health.
To perform optimally, this system relies on a continuous supply of oxygen and nutrients delivered by the cardiovascular system, along with adequate rest and recovery.
