PTSD is a whole-body tragedy, an integral human event of enormous proportions with massive repercussions. ― Susan Pease Banitt
Intergenerational Trauma is the idea that serious trauma can affect the children and grandchildren of those who had the first-hand experience, due to living with a person suffering from PTSD and the challenges that can bring. What’s new is that thanks to the emerging field of epigenetics, science is discovering that trauma is being passed down to future generations through more than simply learned behaviors.
One widely reported example is of holocaust survivors passing on the effects of trauma to children and grandchildren. It seems that trauma or its effects are being passed down through our genes, and it has enormous consequences for us as a species.
What are we Passing on our Children?
The single most dangerous idea I learned in school is that the genes you get from your parents are passed on to your children, and nothing you do in your life changes them. Thankfully, however, the findings of the new scientific field of epigenetics is starting to change this dangerous attitude. We do indeed pass on the exact same chromosomes from parent to child, however, the quality they are in when we receive them can be improved or diminished according to what happens to us and the choices we make during our lifetime.
The reason why it’s dangerous for us to believe otherwise is that it has lead to entire generations of people believing that their choices concerning their own body and the environment affecting it have no detrimental effect on the genes of future generations. In short, it has the potential to see us devolve, simply out of ignorance. Fortunately, as awareness of epigenetics spreads, it’s helping people understand that how we live our lives can change the quality of our own genes for the better and those we pass on to our offspring.
What Is Epigenetics?
We all know the image of a DNA double helix. Imagine now that each of the thirteen rungs in the spiral ladder that makes a chromosome is not simply a rung, but a binary, amino acid on/off switch. You may have received an exact same chromosome that your mother or your father carried, but this chromosome has been changing according to the way you’ve been living your life Some rungs in the ladder are off where they were once on and vice versa. Your genes are responding to the environment like you are, because like you are, they are alive.
Our DNA exists at the heart of our cells and provide the instructions for new cells to be created, so better quality DNA equals better quality instructions for cells to be created and in turn a happier, healthier body. On the other hand, continued degradation of the epigenetic structure of our genes could be leading to lowering of immunity and fertility and increased susceptibility to cellular mutation.
When Emotional Trauma Becomes Overwhelming
In simple terms, trauma occurs when we reach a point where we can’t cope, we are overwhelmed and we don’t have the tools or skills to find our way through. We find ourselves in a state where our sympathetic nervous system goes into overdrive and we can get stuck in fight or flight mode for far longer than our body is designed to remain that way. Sustaining this state of high alert causes depletion and disruption of the normal functions of our system. In our culture, we refer to acute cases of this as PTSD, post-traumatic stress disorder.
Thanks to this diagnosis, we have this somewhat arbitrary boundary which almost says that the truly traumatized people are on one side and the rest of us are on the other. The reality is that the boundary between those who suffer from PTSD and everyone else was invented, created, made up by the human mind with little regard for the fact that trauma is carried within us all in varying degrees. Each of us is on a sliding scale that goes all the way up to and past the line that tips a person into being diagnosed with PTSD.
The kind of trauma we all carry can include the smallest things like the time we were laughed at for not knowing the answer to a question or other seemingly insignificant things like being teased as a child. It can include any moments of pain and tragedy that have occurred throughout our life, but by far the biggest factor of whether the pain remains with us as trauma is whether it was overwhelming and whether it continued to be overwhelming.
