Have you ever heard the saying, “Sticks and stones may break my bones, but words will never hurt me”? This phrase, often repeated to children on playgrounds, is meant to teach resilience. It suggests that while physical aggression is a threat, what someone says is just air—fleeting and harmless.
But anyone who has ever heard something that broke their heart knows this is a lie.
Words are not just sounds. They are carriers of meaning, emotion, and intention that can penetrate deeper than a knife’s blade. A physical wound heals in a few weeks. A broken bone knits together and often becomes stronger in that spot. But a word spoken in anger, a sneer thrown your way in a moment of vulnerability, or cold criticism from a loved one—these things stay with us for years. Sometimes for a lifetime.
In this article, we’ll look at the destructive power of words from three perspectives: the hard science of neurobiology, which sees the pain in our brains; psychology, which studies the scars on our personality; and spirituality, which reminds us of the profound responsibility we have for what comes out of our mouths.
The Brain Sees No Difference: The Neurobiology of Verbal Pain
For a long time, physical and emotional pain were considered two separate phenomena. Physical pain had its place in the body and specific nerve pathways, while emotional pain was something “invented” by the mind, something metaphorical. Modern neurobiology is dismantling this myth.
Semantic Pain is Real Pain
Scientists use the term “semantic pain” to describe the brain’s reaction to words carrying a negative emotional charge. Studies using functional magnetic resonance imaging (fMRI) show something astonishing. When we hear offensive words or experience social rejection, the same areas of our brain that are responsible for feeling physical pain—including the anterior cingulate cortex and the insula—become active.
To your brain, there isn’t a huge difference between hitting your finger with a hammer and having someone you love tell you that you’re worthless. The “pain matrix” in your head lights up in both cases. Evolutionarily, this makes sense. For our ancestors, being excluded from the group (social rejection) meant death. So, the brain developed an alarm system that interprets verbal attacks and rejection as direct threats to life, just as serious as a physical injury.
A Mark on the Nervous System
What’s more, words can physically change the structure of our brain. Long-term exposure to verbal aggression, especially in childhood, can lead to changes in the development of the hippocampus and amygdala—structures responsible for memory and emotion.
This means that hurtful words don’t just “go in one ear and out the other.” They literally sculpt our nervous system, making us more susceptible to stress, anxiety, and depression in the future. This is not a metaphor; it’s a biological fact. Words leave a mark on brain tissue just as a scar remains on the skin.
The Psychological Echo: When Wounds Don’t Heal
Now that we know the brain registers words as pain, let’s look at it from a psychological perspective. Verbal abuse is often downplayed because it doesn’t leave bruises. It’s harder to prove, and the victim often hears, “you’re overreacting,” “you’re too sensitive,” or “it was just a joke.”
It is this invisibility that makes the psychological effects so devastating.
The Erosion of Self-Worth
Verbal abuse isn’t just about yelling and insults. It’s also subtle jabs, sarcasm, constant criticism, or the “silent treatment.” These behaviors act like water dripping on a stone. A single incident can be painful, but chronic exposure to such messages leads to an erosion of identity.
A person subjected to constant criticism begins to internalize these messages. The aggressor’s voice becomes their own inner voice. An adult who was told as a child that they were “stupid” or “clumsy” won’t think, “I made a mistake, I’ll fix it,” when they make a small error at work. They’ll think, “I’m hopeless, I messed up again.” This is a psychological prison built with words.
From my own life, I know how this works. I have a very specific, sharp sense of humor. My friends used to joke that with my cutting remarks, I wouldn’t “die a natural death”—someone would eventually get me for my jokes. For a long time, I didn’t realize that what was funny to me and some friends could be deeply hurtful to others. My words, intended as banter, sometimes landed as blows, chipping away at someone’s confidence without me even noticing. It’s a hard lesson to learn that your intent doesn’t cancel out the impact.
Trauma and Post-Traumatic Stress Disorder (PTSD)
Psychologists are increasingly diagnosing victims of verbal abuse with symptoms identical to Complex Post-Traumatic Stress Disorder (C-PTSD). This manifests as hypervigilance, outbursts of anger, anxiety, depression, and emotional flashbacks.
Children are particularly vulnerable. Their psyche is plastic and absorbent. The words of a parent or teacher are like gospel to a child. If a child hears they are a burden, their developing psyche builds its foundations on a sense of being unwanted. These foundations are incredibly difficult to rebuild in adulthood and often require years of therapy.
The Spiritual Weight of Words: Life and Death in the Power of the Tongue
When we move beyond biology and psychology, we enter the spiritual realm. Here, words take on an even more powerful meaning. In many spiritual traditions, the word is a creative act. “In the beginning was the Word”—this sentence opens the Gospel of John, suggesting that the reality we know originated from an act of speech.
Responsibility for Energy
From a spiritual perspective, words are carriers of energy. They are not neutral. Every spoken sentence is like sending an energetic charge into the world, with the power to build or destroy. The ancient wisdom of the Bible, found in Proverbs 18:21, states it plainly: “Death and life are in the power of the tongue.” This is not a poetic exaggeration. It’s a statement of fact that with our words, we can “kill” someone’s spirit, dreams, or hope, or breathe new life, courage, and faith into them.
Spirituality teaches us that what comes out of our mouths is a testament to the state of our heart (or spirit). Verbal aggression, gossip, mockery—these are all symptoms of inner disorder, pain, or spiritual immaturity. Someone who is fulfilled and connected to the Source (God, a Higher Power) has no need to hurt others with words.
The Power of Silence and Action
My own story taught me this in the harshest way. In my marriage, I failed to build up my wife’s sense of value. I often criticized her actions instead of giving her space, even when I simply disagreed with her methods. I thought my way was “better,” and my words created a space of judgment, not support. This undoubtedly contributed to our separation.
The true weight of words, however, became terrifyingly clear when our relationship was collapsing. After she confessed to another affair and said she wanted to leave, I tried to fix things. I supported her with my actions, helping in many areas and taking primary care of our children, despite my own pain. But my words became weapons. Instead of offering empathy or simply remaining silent, I criticized her and her lover, questioning her choices. I could see my words landing like physical blows, pushing her further away, even as my actions were trying to pull her closer.
This experience showed me that sometimes, the absence of negative words can be more valuable than positive actions. Even with her struggles—which she described as including depression and possibly other personality disorders—my role wasn’t to judge but to offer a space of quiet strength. I learned that in moments of crisis, silence seasoned with empathy can be the most powerful act of love. My empathy should have been stronger than my pain.
The Path to Healing and Mindfulness
The process of healing from hurtful words is not only a matter of brain science and psychology—it’s also intimately linked with forgiveness. If you’ve read my article, “The Power of Forgiveness: Healing Yourself and Others,” you know that forgiveness is not about letting someone “off the hook” or condoning what they did. In my own experience, true healing began only when I learned to forgive—not just my former partner for her choices, but also myself for the words and actions I regretted. That act of release allowed me to reclaim my peace and move forward, no longer shackled to the pain of the past.
Research backs up this transformative power: forgiveness has profound psychological benefits, reducing chronic stress, improving physical health, and breaking cycles of rumination or resentment. Spiritually, forgiveness is a conscious choice to set yourself free, to stop identifying with the role of the victim, as I explored more deeply in that post. Through forgiveness, we not only cut the ties binding us to hurtful memories, but we open ourselves to compassion, growth, and new beginnings—for ourselves and those around us.
Knowing how much words can hurt can be overwhelming, but it also brings hope. If words have such power to destroy, they also have an equal power to heal. The brain’s neuroplasticity—its ability to change throughout life—means we can “overwrite” old, painful pathways with new, positive experiences.
Here’s how we can begin the process of healing and change:
1. Mindful Speech
Before you say something, especially in moments of emotion, pause. Ask yourself three questions (the Socratic test):
- Is it true?
- Is it kind?
- Is it necessary?
If the answer to any of these is “no,” it’s better to remain silent. Mastering the tongue is one of the most difficult, yet most important, spiritual disciplines.
2. Rewriting the Inner Dialogue
If you are a victim of verbal wounds, your task is to change your inner narrator. Cognitive-behavioral therapy, affirmations, or contemplative prayer can help you catch automatic, negative thoughts (which are echoes of others’ words) and replace them with the truth about your worth.
3. The Power of Forgiveness
From a spiritual perspective, holding a grudge for words spoken years ago is like drinking poison and expecting it to harm the person who hurt you. Forgiveness does not mean condoning the harm. It means cutting the energetic cord that binds you to the painful word and its sender. It’s a decision to stop letting those words define your future.
4. Be a Source of Good Words
The best way to heal the world from bad words is to flood it with good ones. Appreciate the people around you. Speak aloud about what is beautiful in them. Your word of encouragement might be the only bright spot in someone’s dark day. Remember, just as negative words change the brain, so do words full of love and support—they build cognitive reserve and mental resilience.
Conclusion: Choose Life
We are not defenseless against words, but we also cannot pretend they don’t matter. Words are a powerful tool we wield every day. They can be a weapon that leaves invisible scars on the brain and soul, or a medicine that mends broken hearts.
The choice is yours. The next time you open your mouth, remember the neurobiological and spiritual weight of what you are about to say. Choose words that build, not destroy. Choose words that give life.
Remember: your words shape reality—yours and that of the people around you. Let it be a reality worth living in.
A Challenge for You Today:
Take a quiet moment and reflect on the words you’ve spoken lately—to yourself and to others. Is there a phrase or comment you regret? Or perhaps there’s someone whose day you could brighten with a kind word or a simple “thank you.” Today, choose one small, mindful action: apologize, encourage, or simply listen before you speak. Notice how it feels to intentionally use your words as a force for healing rather than harm. Your next conversation might be the first step in creating a more compassionate reality—one word at a time.
