What is nervous system regulation?
The nervous system, a complex network that regulates almost every aspect of the body and mind, can sometimes become dysregulated due to stress, trauma, or chronic mental health conditions alone. Understanding and managing your nervous system effectively can significantly improve your overall health and well-being.
Nervous system regulation involves managing the autonomic nervous system, which includes the sympathetic nervous system (often known as the 'fight or flight' response) and the parasympathetic nervous system (responsible for 'rest and digest' functions). Effective regulation helps balance physiological responses of these systems, ensuring neither side is overly dominant. This balance is crucial for physical health, emotional stability, and cognitive function.
Sympathetic nervous system
The sympathetic nervous system is often called the "fight or flight" system because it gives the body a burst of energy to respond to perceived threats. It prepares the body for rapid, intense action by:
- Increasing heart rate and blood pressure
- Expanding air passages of the lungs
- Mobilizing stored energy, thereby increasing blood glucose levels
- Slowing down non-essential functions like digestion and urinary output during acute stress
This system is vital for survival, as it primes the body to react swiftly and effectively to dangers.
Parasympathetic nervous system
In contrast, the parasympathetic nervous system is called the "rest and digest" system. It conserves energy as it slows the heart rate, the blood flow, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract. Activities of the parasympathetic nervous system include:
- Decreasing heart rate and blood pressure
- Stimulating salivation and digestive activities
- Promoting relaxation and recovery of the body after stressful episodes
This system helps to regulate your nervous system and maintain a state of calm and balance in the body, restoring it to rest after the threat has passed.
