Trauma in the nervous system

Impactful events in our lives, whether they are mental, physical, or emotional, can leave a lasting imprint and these often happen in our younger years. While the actual impactful and traumatic event may have occurred in the past and no longer be relevant, the effects it has on our autonomic nervous system (ANS) can continue to manifest in our everyday lives.

As pointed out in previous blog posts, the ANS is responsible for regulating our body's unconscious functions, such as heart rate, digestion, and breathing. When we experience trauma, our body's fight-or-flight response is activated, triggering a cascade of physiological changes to help us survive the perceived threat. However, if the trauma is severe or prolonged, it can disrupt the normal functioning of the autonomic nervous system, leading to long-term consequences affecting decision making and choices.

One way in which trauma affects the autonomic nervous system is through dysregulation of the sympathetic and parasympathetic branches. The sympathetic nervous system is responsible for mobilising the body's resources in times of stress, while the parasympathetic nervous system helps the body rest and digest. Trauma can cause an imbalance between these two branches, leading to symptoms such as hypervigilance, anxiety, and difficulty relaxing. When we experience these issues it's like looking at the world in a distorted way, a bit like the perspective in Alice in Wonderland. Small things can seem big and loom over you, distracting you from your true path.

Moreover, trauma can also impact the vagus nerve, a key component of the ANS that plays a crucial role in regulating our emotional responses and social interactions. When the vagus nerve is dysregulated due to trauma, it can result in difficulties with emotional regulation, social engagement, and overall wellbeing.

Even though the actual trauma may have occurred in the past, the autonomic nervous system's response to it can persist in our everyday lives. This can lead to a heightened state of arousal, emotional reactivity, and difficulty in forming and maintaining relationships. It's important to recognise the impact of trauma on the ANS and seek appropriate support and interventions to help regulate its functioning.

In conclusion, trauma can have a profound effect on the autonomic nervous system, leading to long-lasting consequences impacting our choices that impact our daily lives. By understanding how trauma manifests in the nervous system and seeking support to regulate its functioning, we can work towards healing and creating a sense of safety and wellbeing in our lives.
