People’s words and actions can actually shape your brain — a neuroscientist explains how
The below article highlights why as social creatures we require connections and interactions that feel good, its hardwired into us as a basic need. Our bodies and brains literally experience deterioration and deficit in interpersonal situations that cause us stress. . As a therapist, I see social connections as being crucial in our health and well-being. I regularly work with people who have faced social and interpersonal trauma: usually following an accumulation of experiences such as verbal and physical aggression/harm, bullying, social rejection and neglect. These experiences are more often than not devastating and play a significant role in shaping how an individual relates to themselves, others and the world around them. I want to emphasize that there is hope however! Just having one or even a few people around us who provide consistency, safety, trust and 'good vibes' can make a huge difference: for many people who have experienced interpersonal trauma this in itself is healing. Therapy can also provide a helpful space towards learning how to move towards building connections & interactions that are safe, affirming and generally bring out the good in us.

People’s words and actions can actually shape your brain — a neuroscientist explains how
We humans are a social species. We live in groups. We take care of one another. We build civilizations.
Our ability to cooperate has been a major adaptive advantage. It has allowed us to colonize virtually every habitat on Earth and thrive in more climates than any other animal, except maybe bacteria.
Part of being a social species, it turns out, is that we regulate one another’s body budgets — the ways in which our brains manage the bodily resources we use every day. For your whole life, outside of your awareness, you make deposits into other people’s body budgets, as well as withdrawals, and others do the same for you. This has pros and cons, as well as profound implications for how we live our lives.
Your family, friends and even strangers contribute to the structure and function of your brain and help it keep your body humming along.
How do the people around you influence your body budget and rewire your adult brain? Your brain changes its wiring after new experiences, a process called plasticity. Microscopic parts of your neurons change gradually every day. Branch-like dendrites become bushier, and their associated neural connections become more efficient. Little by little, your brain becomes tuned and pruned as you interact with others.
Some brains are more attentive to the people around them and others less so, but everybody has somebody. Ultimately, your family, friends, neighbors and even strangers contribute to your brain’s structure and function and help your brain keep your body humming along.
This co-regulation has measurable effects. When you’re with someone you care about, your breathing can synchronize, as can the beating of your hearts — whether you’re in casual conversation or a heated argument. This sort of physical connection happens between infants and caregivers, therapists and clients, even people taking a yoga class or singing in a choir together.
If you raise your voice or just your eyebrow, you can affect what goes on inside other people’s bodies.
We also adjust each other’s body budgets by our actions. If you raise your voice or just your eyebrow, you can affect what goes on inside other people’s bodies, such as their heart rate or the chemicals carried in their bloodstream. If a loved one is in pain, you can lessen their suffering merely by holding their hand.
Being a social species has all sorts of advantages for us humans, including the fact that we live longer if we have close, supportive relationships with others. Studies show that if you and your partner feel that your relationship is intimate and caring, that you’re responsive to each other’s needs and that life seems enjoyable when you’re together, both of you are less likely to get sick.
And if you’re already sick with a serious illness, such as cancer or heart disease, you’re more likely to get better. These studies were conducted on married couples, but the results appear to hold for close friendships and for pet owners too.
We also get sick and die earlier when we persistently feel lonely — possibly years earlier, based on the data.
In general, being a social species is good for us, but there are also disadvantages. We also get sick and die earlier when we persistently feel lonely — possibly years earlier, based on the data. Without others helping regulate our body budgets, we bear an extra burden inside.
Have you ever lost someone through a breakup or a death and felt like you’d lost a part of yourself? That’s because you did — you lost a source of keeping your bodily systems in balance.
A surprising disadvantage of shared body budgeting is its impact on empathy. When you have empathy for other people, your brain predicts what they will think and feel and do. The more familiar the other people are to you, the more efficiently your brain predicts their inner struggles. The whole process feels natural, as if you were reading another person’s mind.
But there’s a catch — when people are less familiar to you, it can be harder to empathize. You might have to learn more about the person, an extra effort that translates into more withdrawals from your body budget, which can feel unpleasant. This may be one reason why people sometimes fail to empathize with those who look different or believe different things and why it can feel uncomfortable to try. It’s metabolically costly for our brains to deal with things that are hard to predict.
A hateful word may cause your brain to flood your bloodstream with hormones, squandering resources from your body budget.
No wonder people create so-called echo chambers, surrounding themselves with news and views that reinforce what they already believe — it reduces the metabolic cost and unpleasantness of learning something new. Unfortunately, it also reduces the odds of learning something that could change a person’s mind.
We also regulate each other with words — a kind word may calm you, like when a friend gives you a compliment at the end of a hard day. And a hateful word may cause your brain to predict threat and flood your bloodstream with hormones, squandering precious resources from your body budget.
The power of words over your biology can span great distances. I can text the words “I love you” from the US to my close friend in Belgium, and even though she cannot hear my voice or see my face, I will change her heart rate, her breathing and her metabolism.
Or, someone could text something ambiguous to you like “Is your door locked?” and odds are that it would affect your nervous system in an unpleasant way.
Your nervous system can be perturbed not only across distances, but also across centuries. If you’ve ever taken comfort from ancient texts such as the Bible or the Koran, you’ve received body-budgeting assistance from people long gone.
Books, videos and podcasts can warm you or give you the chills. These effects might not last long, but research shows that we all can tweak one another’s nervous systems with mere words in very physical ways that go beyond what you might suspect.
The power of words is not a metaphor; it’s in our brain wiring.
Why do the words you encounter have such wide-ranging effects inside you? Because many brain regions that process language also control the insides of your body, including major organs and systems that manage your body budget.
These brain regions are contained in what scientists call the “language network” and guide your heart rate up and down. They adjust the glucose entering your bloodstream to fuel your cells. They change the flow of chemicals that support your immune system.
The power of words is not a metaphor; it’s in our brain wiring. We see similar wiring in other animals; for example, neurons that are important for birdsong also control the organs of a bird’s body.
Words, then, are tools for regulating human bodies. Other people’s words have a direct effect on your brain activity and your bodily systems, and your words have that same effect on other people. Whether you intend that effect is irrelevant. It’s how we’re wired.
Does this mean that words can be harmful to your health? In small doses, not really. When someone says things you don’t like, insults you or even threatens your physical safety, you might feel awful.
Over time, anything that contributes to chronic stress can gradually eat away at your brain — this includes verbal aggression, social rejection and neglect.
Your body budget is taxed in that moment, but there’s no physical damage to your brain or body. Your heart might race, your blood pressure might change, you might ooze sweat, but then your body recovers and your brain might be a bit stronger afterward.
Evolution gifted you with a nervous system that can cope with temporary metabolic changes and even benefit from them. Occasional stress can be like exercise — brief withdrawals from your body budget followed by deposits create a stronger, better you.
But if you are stressed over and over and over again without much opportunity to recover, the effects can be far more grave. If you constantly struggle in a simmering sea of stress and your body budget accrues an ever-deepening deficit, that’s called chronic stress. It does more than just make you miserable in the moment.
Over time, anything that contributes to chronic stress can gradually eat away at your brain and cause illness in your body. This includes physical abuse, verbal aggression, social rejection, neglect and the countless other creative ways that we social animals torment one another.
It’s important to understand that the human brain doesn’t seem to distinguish between sources of chronic stress. If your body budget is already depleted by the circumstances of life — like physical illness, financial hardship, hormone surges, not sleeping or exercising enough — your brain becomes more vulnerable to stress of all kinds. This includes the biological effects of words designed to threaten, bully or torment you or people you care about.
When your body budget is continually burdened, momentary stressors pile up, even the kind you’d normally bounce back from. It’s like children jumping on a bed — the bed might withstand 10 kids bouncing but the 11th one snaps the bed frame.
Simply put, a long period of chronic stress can harm a human brain. When you’re on the receiving end of sustained verbal aggression, studies show you’re more likely to get sick. Scientists don’t understand all the underlying mechanisms yet, but we know it happens.
These studies of verbal aggression tested average people across the political spectrum, left, right and center. If people insult you, their words won’t hurt your brain the first or second time or maybe even the twentieth.
We are free to speak and act, but we are not free from the consequences of what we say and do.
But if you’re exposed to verbal aggression continually for months or if you live in an environment that relentlessly taxes your body budget, words can physically injure your brain. Not because you’re weak or a so-called snowflake, but because you’re a human.
Your nervous system is bound up with the behavior of other humans, for better or for worse. You can argue what the data means or if it’s important, but it is what it is.
It’s the fundamental dilemma of the human condition: The best thing for your nervous system is another human and the worst thing for your nervous system is another human. Scientists are often asked to make our research useful to everyday life, and these findings about words, chronic stress and disease are a perfect example. There is a real biological benefit when people treat one another with basic human dignity.
A realistic approach to our dilemma is to realize that freedom always comes with responsibility. We are free to speak and act, but we are not free from the consequences of what we say and do. We might not care about those consequences or we might not agree that those consequences are justified, but they nonetheless have costs that we all pay.
We pay the costs of increased health care for illnesses — like diabetes, cancer, depression, heart disease and Alzheimer’s disease — that are worsened by chronic stress. We pay the costs of ineffective government when politicians spew vitriol at one another and make personal attacks instead of having reasoned debate. We pay the costs of a citizenry that struggles to discuss politically charged topics with one another productively, a standoff that weakens our democracy.
As our society makes decisions about health care, the law, public policy and education, we can ignore our socially dependent nervous systems, or we can take them seriously. Our biology won’t just go away.
