What Childhood Taught the Nervous System
READ — ABOUT 8 MINUTES
Years ago, my family and I went to a posh restaurant in Pasadena, California.
There were six of us, and the dinner marked a special occasion. We were excited about the experience. The restaurant was busy, but after we were seated, the attention we received seemed inadequate. Our water glasses were filled and refilled—we must have consumed gallons of water—yet we waited an extraordinarily long time to order and receive our food.
I recall that nearly an hour passed before our meal arrived.
Leaving for another restaurant would not have been practical. So we stayed. We ate. The food was good, and we managed to enjoy parts of the evening, but the experience was far from what we had anticipated.
My greatest complaint was not simply the delay. It was the lack of communication. No one seemed willing to acknowledge what was happening or assure us that we had not been forgotten.
Shortly afterward, I wrote the restaurant a two-page letter—in 12-point font.
The restaurant responded by sending gift certificates that covered the cost of our dinner that evening and then some.
At the time, that outcome may have seemed like proof that my response was justified. The service had, in fact, been poor. The restaurant agreed that something had gone wrong.
But the letter was also one of my milder responses.
Over the years, I sometimes lashed out severely at customer-service representatives. There were occasions when confronting someone seemed almost recreational. I am not proud of that.
Today, I am decidedly better regulated. It has been—and remains—work.
When the Reaction Is Larger Than the Moment
What took me much longer to understand was that the immediate situation did not always account for the intensity of my response. The person on the telephone, the delayed order, or the unanswered question might have been the present trigger, but something older was sometimes supplying the force.
The present moment had touched an old place.
The Map
The Centers for Disease Control and Prevention and Kaiser Permanente conducted the original Adverse Childhood Experiences Study, commonly called the ACE Study, from 1995 to 1997.
The study examined ten categories of adversity occurring before age eighteen:
- Emotional abuse
- Physical abuse
- Sexual abuse
- Emotional neglect
- Physical neglect
- Violence toward one’s mother or stepmother
- Substance misuse in the household
- Mental illness in the household
- Parental separation or divorce
- An incarcerated household member
Each category a person experienced counts as one point. The total is commonly called an ACE score.
Researchers found what is described as a graded relationship: as the number of reported childhood adversities increased, the risk of various difficulties in health and well-being also increased.
The ACE Study did not establish that every person with a particular score would experience a particular outcome. It revealed patterns of risk across a large group of people.
That distinction matters.
An ACE score is not a diagnosis. It does not measure how often something happened, how severe it was, when it occurred, or how the child understood it. The score does not include every form of childhood adversity. Nor does it account fully for the people, faith, community, opportunities, and other protective influences that may have helped a child endure.
The score tells us something important.
It does not tell us everything.
My ACE score was seven.
Learning that number did not place a curse over my life. It did not define my character or remove my responsibility for the ways I treated other people. It gave me information—a map that helped me recognize that some of my adult reactions had roots.
What the Nervous System Learned
Dr. Nadine Burke Harris, a pediatrician and former Surgeon General of California, has helped bring widespread attention to the relationship between childhood adversity, toxic stress, and lifelong health.
When a child repeatedly experiences danger, instability, neglect, or fear without adequate protection and support, the body’s stress-response system may remain activated for too long. The child’s developing brain and body learn to prepare for threat.
That response can be lifesaving when danger is present.
The difficulty is that the nervous system may continue using what it learned long after the original danger has passed.
An unanswered request may feel like more than inconvenience.
A delayed response may feel like abandonment.
A lack of communication may feel like being disregarded.
A disagreement may feel like danger.
The adult may know intellectually that the present situation is manageable, while the body responds as though something much greater is at stake.
This does not mean that every strong reaction is caused by childhood trauma. Poor service is still poor service. Mistreatment should not be renamed or ignored. Boundaries remain necessary.
But sometimes the size of the reaction invites another question:
Am I responding only to what is happening now, or also to something that happened before?
For me, the work was not merely learning how to complain more politely. It was learning to notice what happened inside me when I believed I was being ignored, dismissed, or treated as though I did not matter.
That recognition did not excuse my conduct. It increased my responsibility.
Once I could see more clearly, I could begin to choose more intentionally.
The Lantern
Paul wrote:
“And be not conformed to this world: but be ye transformed by the renewing of your mind.”
—Romans 12:2, KJV
Renewing the mind is not pretending that painful things did not happen. It is not covering an activated nervous system with a Bible verse and calling the work complete.
Renewal begins with truth.
What happened?
What did I learn in order to survive it?
What does my body expect when I feel ignored, cornered, rejected, or unsafe?
Is that expectation accurate in this present moment?
What response agrees with who God is calling me to become?
The renewing of the mind allows us to examine an old message without continuing to obey it.
I can recognize, Something in me feels disregarded, without deciding that the person in front of me deserves the accumulated force of every earlier wound.
I can address a problem firmly without becoming cruel.
I can ask for accountability without trying to make another person feel powerless.
I can pause before handing an innocent person a bill for pain they did not create.
For me, this is part of loving my neighbor as myself in practice. I am included in that command, but so is the customer-service representative. So is my family. So is every person within earshot of my response.
Buffering the Effects
Dr. Burke Harris’s work emphasizes that our biology is not our destiny. Practices that help regulate the stress response can help buffer the effects of trauma, recognizing that people may be affected differently by similar experiences.
These include:
- Supportive, trustworthy relationships
- Regular physical activity
- Sufficient, consistent sleep
- Balanced nutrition
- Mindfulness and contemplative practices
- Access to appropriate mental-health care
- Time in nature
These are not punishments for having survived adversity. They are ways of helping the brain and body experience safety, steadiness, and connection repeatedly.
For a Christian, prayer, Scripture, worship, wise counsel, and healthy fellowship may also be part of that practice. Faith does not make professional support unnecessary, and professional support does not make faith irrelevant. Help can come through more than one door.
In the moment of activation, buffering may begin with something very small:
Pause before responding.
Place both feet on the floor.
Take a slow breath.
Name what is happening without judging yourself.
Ask whether the situation is dangerous, distressing, or merely disappointing.
Delay the email or telephone call until your body has settled.
Speak to someone safe.
Choose the outcome you want before choosing your words.
Repair the harm when you fail.
No single practice erases the past. Repetition matters. Regulation is not a one-time achievement; it is a capacity we continue to strengthen.
I am better regulated today, but I do not write that as someone who has arrived. I write as someone who has learned to recognize the road.
A Gentle Invitation
If you decide to calculate your ACE score, move gently.
You do not have to disclose your score to anyone. You do not have to retrieve every memory at once. If the questions become overwhelming, you may stop. If painful memories are disrupting your daily life, consider seeking support from a qualified, trauma-informed professional.
Then remember what the number can and cannot tell you.
Your score may help identify exposure.
It does not measure your worth.
It may help explain certain vulnerabilities.
It does not determine your future.
It may reveal what your nervous system once needed to learn.
It does not dictate what you must continue practicing.
Reflect
When do my reactions seem larger than the present situation?
What does being ignored, corrected, delayed, or disappointed awaken in me?
What might my nervous system have learned in order to protect me?
Which of those lessons still serve me?
Which responses now require renewal?
What is one buffering practice I can begin—or return to—this week?
Where might repair be needed?
Childhood may have taught the nervous system how to survive.
With truth, support, practice, and the renewing work of God, we can continue to learn new ways to respond to the effects of trauma.
The map shows me what is. The lantern guides what I choose next.
