PTSD: Understanding the Daily Effects on the Nervous System


Today, I want to talk about PTSD or Post-Traumatic Stress Disorder. PTSD is a mental health condition that affects millions of people worldwide. I was diagnosed shortly after finding my husband passed away. Many circumstances and traumatic events can cause PTSD. In this article, I want to focus on understanding its impact on the nervous system. This knowledge can illuminate the physical and emotional challenges faced by those living with the disorder. My symptoms have become worse this spring in anticipation of his fifth death anniversary. After some research, I want to share what I’ve learned. By diving in and learning the everyday effects PTSD has on the nervous system, we can better understand it. We can also support ourselves and others who are impacted by it.

The Basics of PTSD and the Nervous System

In short, PTSD arises after a person experiences or witnesses a traumatic event. Symptoms can include flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the event. The nervous system plays a vital role in how individuals process trauma, as it regulates emotions and responses.

The Stress Response and Hyperarousal

Recently, I’ve found myself jumping to sudden noises. I felt like I was always anxious, just waiting for something to “happen.” It turns out this is the nervous system’s fight-or-flight response. It’s often activated in PTSD, causing what’s called chronic hyperarousal. Individuals might feel constantly on edge, have difficulty sleeping, or be easily startled. This sustained state of alertness can significantly affect daily life, leading to exhaustion and increased stress.

Intrusive Thoughts and the Brain’s Reactions

PTSD can trigger the brain to relive traumatic experiences through intrusive thoughts and memories. Flashbacks can occur, making distinguishing between past and present threats challenging for the nervous system. Fortunately, I was able to find a therapist to administer EMDR for my flashbacks, but this isn’t always the case, depending on the type of trauma endured. Therefore, this reaction can lead to increased anxiety and difficulty concentrating.

Emotional Regulation Difficulties

With this recent relapse, I found myself crying more and experiencing bouts of sadness out of nowhere. I discovered that emotional regulation becomes a struggle for those with PTSD. The nervous system may find it hard to return to a calm state after a trigger. For me, I can experience severe symptoms for weeks. This can result in heightened emotions, such as anger or sadness, impacting relationships and day-to-day interactions.

Physical Symptoms of PTSD on the Nervous System

PTSD also manifests physically. The main thing I want to emphasis is that everyday triggers can complicate and overload the nervous system. Often, it can cause tension headaches, digestive issues, and muscle pain. These symptoms arise from the nervous system’s prolonged stress response, substantiating the disorder’s expansive effect beyond the mind.

Coping Strategies and Healing the Nervous System

It’s easy to get discouraged and think that living in a perpetual anxious state is going to be the norm, but it doesn’t have to be. Symptoms can be managed successfully. Managing PTSD requires strategies that soothe the nervous system. Techniques such as mindfulness, deep breathing exercises, and meditation can aid in calming the body. Various therapeutic approaches exist. They aim to rewire neurological responses and promote recovery.


Understanding PTSD’s impact on the nervous system helps with understanding the complexities of the disorder. Offering insights into its daily effects can provide a foundation for empathy and support in ourselves and those around us, whether we are suffering or know someone suffering. While the journey through PTSD is challenging, hope persists through awareness and effective coping strategies, paving the way for healing.
