Meaning
Autonomic asymmetry defines the state where the sympathetic branch of the nervous system exerts greater influence over physiological functions than the parasympathetic branch. This imbalance keeps the body in a state of mobilization, even when the environment is safe and quiet. Through sympathovagal dominance, the system prioritizes rapid response over long-term maintenance.
The state ends when the vagus nerve successfully reasserts control over the heart and lungs.
Systemic Tension
High sympathetic activity increases blood pressure and suppresses the immune system. When sympathovagal dominance is the default state, the body is unable to enter the repair mode necessary for health. This leads to a gradual erosion of physical and mental resilience.
Regulatory Drift
Alarm triggers lower the baseline requirement for a response. As the system remains in a state of sympathovagal dominance, minor social stressors are processed with the same intensity as major threats. This drift ensures that the person stays in a state of high alert.
Allostatic Burden
The cumulative cost of staying in a state of dominance is a shortened lifespan for the cells and the system as a whole. A founder in this state experiences the world as a series of urgent crises that require an immediate surge of adrenaline. This constant surge burns through the available supply of neurotransmitters and hormones.
Eventually, the system loses the ability to return to a calm baseline, even during a vacation. The permanent elevation of the stress floor makes every future load more expensive to carry and harder to shed.
