How Childhood Trauma Affects Mental and Physical Health

How Childhood Trauma Affects Mental and Physical Health

Thursday, February 20, 2025

How childhood experiences shape both mental and physical health in the long run.

While exploring different materials on trauma and its effects, I came across an interview with a somatic therapist who mentioned the ACE (Adverse Childhood Experiences) study. Curious, I dug deeper, and what I found was both shocking and crucial—yet surprisingly, not common knowledge. This information needs to be widely shared because it affects so many lives!

Most people who have learned about mental health or gone through therapy understand that trauma can lead to emotional struggles. For example, someone with depression might trace it back to growing up with an alcoholic parent who was often angry and unpredictable. But what’s truly eye-opening is that childhood trauma doesn’t just affect mental health—it can also lead to chronic physical illnesses like migraines, heart disease, and autoimmune conditions.

What Does the ACE Study Say?

The original ACE study was conducted in the 1990s in the U.S., and since then, many studies worldwide have confirmed and expanded its findings.

What counts as an ACE? Adverse Childhood Experiences include a wide range of difficult or traumatic situations, such as:

  • Physical, sexual, or emotional abuse
  • Neglect
  • Losing a family member to suicide
  • Parents separating or divorcing
  • Growing up with a caregiver who struggled with addiction or mental illness
  • Bullying at school

Key Findings from the Study

  1. ACEs are extremely common. Two-thirds of study participants had experienced at least one ACE, and 25% had gone through three or more.
  2. The more ACEs a person experiences, the higher their risk of serious health problems.

Research shows that people who had four or more ACEs as children have a significantly higher chance of developing chronic illnesses like diabetes, high blood pressure, heart disease, respiratory diseases, liver disease, obesity, and depression. Another study found that ACEs can also increase the risk of autoimmune diseases such as rheumatoid arthritis.*

A Different Perspective

This research offers a deeper understanding of how our early experiences shape our long-term health. It’s interesting to consider how addressing trauma might not only impact mental well-being but also influence physical health in ways we don’t always expect.

In my opinion, it makes sense to focus on the root cause rather than just managing symptoms. If childhood trauma plays such a major role in long-term health, then addressing it directly might be a more effective way to improve both mental and physical well-being. There’s still so much to learn in this area, and it raises important questions about how past experiences connect to present health challenges.

This book offers a vivid and personal account of a childhood trauma survivor. It shares her journey of realizing what she had experienced and how she navigated recovery. It will be especially valuable for those going through a similar process. What makes it even more relevant is that her experience is recent, allowing readers to connect with it on a current and relatable level.
Mastin Kipp. Reclaim Your Nervous System. A Guide to Positive Change, Mental Wellness, and Post-Traumatic Growth While this book isn’t at the top of my list in terms of value for my learning journey, I appreciate Mastin for two things. First, for having the courage to share his perspective despite not being a 'qualified' doctor or therapist. Second, for his approach to trauma recovery—working across past, present, and future—which I completely agree with.
Richard Strozzi-Heckler. The Art of Somatic Coaching. Embodying Skillful Action, Wisdom, and Compassion This was one of the most challenging books I’ve read so far. The language was complex, making it difficult to grasp the author’s messages. Still, I pushed through, found many of the examples valuable, and finished with one key takeaway—somatic work is incredibly useful in trauma healing.
Judith L. Herman. Trauma and Recovery: The Aftermath of Violence -- From Domestic Abuse to Political Terror
This is quite an old book, and some of its examples and descriptions of modern challenges feel a bit outdated. Still, it was important for me to read it. First, it offers an excellent overview of the 'history' of trauma and the approaches used to treat it. Second, it presents a primarily cognitive perspective on trauma treatment, which adds valuable insight to my knowledge base.
