You can eat well, sleep well, and still get blindsided by migraines.
[00:06]
Because not all triggers are physical.
[00:09]
In this episode, we uncover 5 subtle ways boundary-violating people dysregulate your
[00:14]
nervous system and lower your migraine threshold.
[00:17]
And more importantly, what to do without guilt, confrontation, or burning bridges.
[00:26]
Welcome to the Migraine Heroes podcast.
[00:29]
A podcast for people living with chronic migraines, years of pain, misunderstanding,
[00:35]
I'm Diane Ducarme, and I've helped more than a thousand people reduce the burden
[00:40]
of migraines and feel more in control.
[00:43]
Each episode brings you grounded insights into what your body might be asking for and
[00:48]
what can truly help.
[00:51]
Recently, Linda, who went through the Migraine Heroes journey, came to visit me in New Zealand.
[00:57]
She talked to me about how much had changed, not just her migraines, but how she understands
[01:03]
herself, how she makes decisions, how she feels in control again.
[01:07]
And it reminded me how powerful clarity really is.
[01:11]
The real shift in migraine starts there, with clarity.
[01:15]
And for many people, migraine feels so confusing, unpredictable, and the constant question is,
[01:22]
why is this happening to me?
[01:25]
When that question begins to have an answer, something changes.
[01:29]
You know what you're working with, and you know what to do next.
[01:34]
That's the kind of work that happens in our 90-minute personal migraine sessions, where
[01:39]
we slow down and apply everything we explore here directly to you, to your history, your
[01:46]
patterns, your questions.
[01:49]
After seeing Linda, I felt deeply grateful, and I wanted to create a space for more of
[01:53]
those conversations.
[01:54]
So this month, this month of March 2026, I've set aside time to personally hold more of
[02:01]
these sessions, and I'm offering them at no cost.
[02:05]
If you'd like to explore your migraines in this way, with me, just book a call in the
[02:10]
show notes of your podcast, or download the Migraine Heroes app, complete your Getting
[02:15]
Started steps, and you'll see how to reserve your session.
[02:19]
This offer is for March 2026 only.
[02:24]
Now take a deep breath, and let's dive in.
[02:35]
In this episode, you will learn how boundary-violating people quietly activate your nervous system,
[02:41]
and why your head takes the hit, five subtle, science-backed ways that stress from toxic
[02:47]
interactions create the perfect storm for a migraine, and what you can do today to start
[02:53]
protecting your energy, reclaim your space, and reduce migraine frequency.
[02:58]
Stay with me till the end, because the fifth trigger will surprise you, especially if you're
[03:04]
always trying to be the nice one.
[03:07]
This episode is dedicated to one woman in particular, someone living with a partner
[03:12]
who repeatedly crosses her boundaries, and seems to take pleasure in doing so.
[03:18]
If she recognizes herself here, I hope she feels my deep affection and my empathy.
[03:25]
Her situation is not simple, not chosen, and not easily escaped, and she deserves far more
[03:32]
peace, safety, and gentleness that she's been given.
[03:37]
Let's begin with what boundary-violating really means.
[03:41]
In psychological terms, these are people who regularly ignore, dismiss, or overstep your
[03:48]
emotional, physical, or energetic limits.
[03:52]
They might interrupt your rest, demand too much, guilt-trip you, or monopolize your energy.
[03:57]
And while it may sound like a social inconvenience, research shows these experiences are biologically
[04:07]
So for a long time, we called these people toxic, and the word was catchy, validating,
[04:13]
and helped name the harm. But it also flattens the picture.
[04:18]
Toxic frames the person as the problem, as if they are universally dangerous, or intentionally
[04:25]
Boundary-violating shifts the lens from who they are to what happens in the relationship.
[04:31]
It's a bit more precise, more humane, and more useful for healing, especially when you
[04:36]
can't leave, when the person isn't evil, or when the harm comes from chronic overstepping
[04:42]
rather than overt abuse.
[04:45]
This language helps explain why your nervous system reacts even in relationships that look
[04:50]
normal on the outside.
[04:52]
The injury isn't the person, it's the repeated erosion of your internal limits.
[04:58]
Now before we go any further, it matters to say this gently, if you're in a relationship
[05:03]
like this, it doesn't mean you're weak, naïve, or bad at boundaries.
[05:08]
Many people don't choose those dynamics, they grow into them slowly, they inherit them
[05:14]
through family roles, through work hierarchies, illness, or caregiving, or fall into them
[05:20]
while they're trying to be kind, loyal, or safe.
[05:23]
Changing or changing them isn't always possible, and it's often emotionally, financially, or
[05:29]
If your body reacts with migraines, that's not a failure, it's your nervous system signaling
[05:34]
overload long before your conscious mind is allowed to.
[05:37]
And if that resonates, know this, migraines are not random in these contexts, they are
[05:43]
patterned responses to emotional dysregulation.
[05:47]
To understand why your body reacts this way, we need to look at what happens inside the
[05:51]
migraine brain when safety, agency, and nervous system boundaries are repeatedly crossed.
[05:57]
So the migraine brain, as we know, is hypersensitive to environmental and internal stressors.
[06:03]
The study published in the Journal of Neurology, Neurosurgery, and Psychiatry confirms that
[06:08]
emotional stress is one of the most commonly reported migraine triggers.
[06:12]
When you interact with someone who makes you feel unseen, or unsafe, it's not in your head,
[06:19]
it's in your nervous system.
[06:21]
So here are the 5 ways boundary violating, or toxic people, can trigger a migraine.
[06:28]
They spike your cortisol.
[06:30]
Boundary violations, especially chronic ones, activates the HPA axis, the hypothalamic pituitary
[06:37]
adrenal, elevating your cortisol and keeping your body in fight or flight state.
[06:43]
And a 2014 study in Headache, the Journal of Head and Face Pain, put a strong link between
[06:48]
elevated cortisol levels and migraine incidence.
[06:52]
They create anticipatory stress.
[06:55]
You're not just reacting to them, you're dreading them.
[06:59]
This form of chronic vigilance keeps your nervous system on high alert, preventing the
[07:03]
deep parasympathetic states where healing occurs.
[07:09]
They drain your emotional reserves.
[07:11]
Constant self-monitoring or emotional caretaking around a person suppresses your body's ability
[07:17]
Studies from Cephalalgia show a correlation between emotional suppression and increased
[07:22]
migraine frequency.
[07:25]
They destabilize your sense of agency.
[07:27]
Gaslighting, or undermining your choices, can reduce your perceived control, a psychological
[07:33]
state shown to intensify pain processing.
[07:38]
They make you override your own needs.
[07:42]
One of the biggest hidden triggers?
[07:45]
Being around people who make it unsafe to say no.
[07:49]
Every time you push past your exhaustion, your brain receives danger signals and often
[07:55]
responds with a migraine.
[07:57]
So that's the perspective from the West.
[07:59]
In the East, this dynamic is rarely framed in terms of people being the problem.
[08:04]
It's understood as a disturbance of energetic boundaries.
[08:08]
In martial arts and spiritual traditions, every human is seen as having a field, a living
[08:15]
responsive space of chi around the body that constantly negotiates contact with the world.
[08:22]
When someone repeatedly intrudes into that field through pressure, dominance, emotional
[08:27]
bullying, criticism, or unpredictability, the body is forced into defense.
[08:32]
It either hardens to protect itself, or becomes hyper-alert, scanning constantly to anticipate
[08:40]
Both states require enormous energy, and neither can be maintained without consequence.
[08:47]
In internal martial arts, the core teaching is never to meet force with force.
[08:53]
Strength comes from staying centered, grounded, and fluid, soft at the edges, stable at the
[09:02]
You are taught to let pressure pass, rather than lodge inside of you.
[09:06]
Healing begins not by fixing the other person, but by rebuilding your internal perimeter
[09:12]
so your system no longer has to scream to be heard.
[09:15]
But when this intrusion is chronic, personal, or emotionally loaded, as it often is in close
[09:21]
relationships, that skill becomes nearly impossible to sustain.
[09:25]
The nervous system loses its ability to settle, breath rises into the chest, muscles brace
[09:30]
and energy that should flow downward begins to surge upward instead.
[09:35]
From this perspective, migraines are not a sign of fragility or over-sensitivity. They
[09:39]
are the biological outcome of a system that has been guarding its perimeter for too long
[09:46]
and without relief.
[09:47]
When energy can no longer disperse through the body safely, it accumulates in the head,
[09:53]
creating pressure, heat, and pain.
[09:55]
Migraine becomes the body's last line of communication, signaling that the boundary
[10:00]
breach has exceeded what the system can quietly absorb.
[10:05]
And this is why we don't treat migraine as a single-issue story.
[10:10]
Here at Migraine Heroes, you'll find podcasts across a wide range of topics. Nervous systems,
[10:16]
safety, boundaries, hormones, food, sleep, emotions, transitions, so you can follow what
[10:21]
your body is asking for.
[10:24]
When you're invited to search the keywords that resonate with you within the Migraine
[10:28]
Heroes podcast, move at your own pace and tailor your learning without pressure or perfection.
[10:35]
Healing is not linear and you don't have to understand everything at once for your
[10:40]
system to begin softening.
[10:42]
Advice of the day.
[10:43]
If this is you, take a one-hour to detox your calendar.
[10:48]
Look at the week ahead and circle any meetings, calls, or texts that
[10:54]
make you feel dread or resentment.
[10:57]
Then, do one of the following, cancel it, delegate it, or reschedule it with a boundary.
[11:03]
If that person lives under your roof, do the opposite.
[11:08]
Create blocks when you can be outside of home, for your own leisure, or with people who give
[11:14]
Your nervous system will notice, and so will your migraine frequency.
[11:19]
And remember, every small step you take moves you closer to freedom.
[11:25]
You are powerful, you are resilient, and you are no longer alone.
[11:30]
Keep rising, Migraine Hero.
