The arguments your back knows by heart
For Léa and Mathieu, arguments always follow the same script. Voices rise, then silence falls. The next day, Léa has a migraine. Mathieu's back seizes up. Twelve years together, and their bodies have been keeping accounts neither of them ever wanted to read. I often see couples arrive with a communication problem and leave with something else entirely: a recovery programme for two nervous systems running on empty.
What a relationship does to the nervous system

Your partner is the person whose signals your body monitors most closely: a shift in tone, a sigh, a door closed a little too hard. When the relationship goes through a rough patch, each person's nervous system switches to permanent vigilance, even during the calm moments. You sleep side by side, but each of you sleeps on alert. That constant tension eventually prints itself somewhere: jaw, neck, back, stomach, sleep. And the longer it lasts, the lower the trigger threshold drops: the smallest thing reignites the argument, because both bodies were already charged before the first word.
Somatization, a faithful messenger
Somatizing doesn't mean making it up. The pain is real: muscles contracted for hours on end, digestion slowed by stress, fragmented sleep that blocks recovery. The body expresses what the relationship can no longer say with words. In some couples, it even becomes the last channel of communication left: you no longer talk, but you hurt together. A medical opinion remains essential for any persistent pain, of course: the body can have several reasons for speaking up.
We thought we had a communication problem. What we really had were two exhausted bodies that could no longer listen to each other.
Calm the bodies before going back to words
This is the most useful reversal: stop trying to settle the conversation while both nervous systems are on alert. A brain in defence mode doesn't listen, it protects itself. Hence one simple rule: never open a sensitive subject while holding your breath. Before the conversation, give yourselves three minutes of breathing, together or each on your own: breathe in for 4 seconds, breathe out for 6. Two calmed bodies don't guarantee agreement, but they make listening physically possible.
When support can help
If the same tensions keep coming back on a loop, they often rest on blocks older than the relationship itself: fear of abandonment, need for control, inherited anger. Brief therapy works on those roots individually, and I'm also trained in couples therapy. The immersions, by the way, include life as a couple among their themes: two nervous systems learning to come back down is already a different relationship.
Your back, their migraines, your nights: all of it is talking about the two of you. To start by calming the bodies, discover the immersive workshops.
