Sympathetic Nervous System
The 'fight or flight' branch of the autonomic nervous system that activates in response to stress or danger. Increases heart rate, blood pressure, and alertness while suppressing digestion and immune function.
Overview
The sympathetic nervous system is the 'fight or flight' system that activates during stress, which may be overactive in some individuals with ADHD.
Detailed Description
The sympathetic nervous system activates in response to perceived threat or stress, increasing heart rate, blood pressure, and alertness while suppressing non-essential functions like digestion. In chronic stress or when not balanced by the parasympathetic system, sympathetic activation can contribute to ADHD symptoms, emotional dysregulation, and physical symptoms. Understanding this helps explain connections between stress and ADHD symptoms.
How This Relates to ADHD
Many individuals with ADHD experience heightened stress responses. Understanding the sympathetic system helps explain these experiences and the importance of stress management.
Treatment and Management
Stress management, relaxation techniques, regular exercise, adequate sleep, and creating supportive environments can help balance sympathetic activation.
Examples
