At first, Léa thought she had caught a weird virus.
Her neck was stiff, her stomach twisted for no reason, and a dull headache sat behind her eyes from breakfast to bedtime. She tried magnesium, drank more water, changed her pillow. Nothing worked.
One evening, a colleague asked her, half-joking, “How many tabs do you have open in your brain right now?” She laughed, then suddenly felt like crying. Because that was exactly it: she was running 47 mental tabs at once, non-stop.
Her body wasn’t “sick”.
It was overloaded.
When your brain behaves like a crashed computer
We rarely connect our spinning thoughts to the knots in our shoulders or the weight in our chest. We blame the chair, the weather, that one pastry at lunch. Anything but the state of our mind.
Yet mental overload works a bit like pushing a laptop with 3% battery to run 20 apps while streaming HD video. At first, it gets hot. Then it slows. Then it freezes. The human version of that freeze looks like migraines, tension in the jaw, random chest tightness, restless nights.
Our body keeps the score of the thoughts we don’t process.
Take Karim, 38, project manager, two kids, a calendar that looks like a Tetris screen. For months, he woke up with stabbing stomach pain. Doctors ran tests. Nothing. “Probably stress,” they said, and sent him home with antacids.
His real schedule? Back-to-back meetings, side messages from his boss, WhatsApps from school, unfinished tasks pinging in his head at 2 a.m. He didn’t rest, he just switched screens. On Saturday mornings, when he finally slowed down, the pain was always worse.
The more his mind raced through invisible to‑do lists, the more his body screamed in very visible ways.
There’s a plain physiology behind all this. When the brain reads “too much, too fast, for too long”, it activates the same alert system as if a dog were chasing you down the street. Heart rate climbs, muscles contract, breathing gets shallow, digestion pauses.
➡️ No vinegar and no baking soda needed: pour half a glass and the drain cleans itself effortlessly
➡️ Elon Musk fired so many staff he had a 20-year-old student train an entire AI engineering team
➡️ China Begins Returning Boeing Aircraft to US
➡️ Why people who ask follow-up questions are perceived as more caring
Short bursts like that are fine. They’re useful. The problem is the “too long” part. Mental overload keeps that alert switch half-on, all day, all week, sometimes all year. Muscles never really let go. The gut never truly returns to calm digestion.
That’s when tension migrates into the neck, sleep fragments, back pain appears “for no reason”, and the body quietly pays the bill for our crowded mind.
Small levers that calm the mind–body loop
One simple gesture changes a lot more than people expect: pausing for 60 seconds and breathing like you’re safe. Not like you’re late. Slowly in through the nose for four seconds, hold for two, out through the mouth for six. Twice. Three times.
This tiny pattern tells the nervous system, “No dog. No danger. You can stand down.” Muscles start to soften, heart rate drops a notch, thoughts lose a bit of their sharp edge. Done regularly, it becomes a reset button for both body and brain.
*It’s boring, almost stupidly simple, and yet it quietly moves the dial on physical discomfort.*
Another lever: lowering your “mental tabs” count on purpose. That means writing tasks down instead of letting them float overhead like storm clouds. One list for work, one for personal life. Not a perfect Notion board. A scrappy note on your phone is enough.
Then you choose three tasks that truly matter today. Just three. Not twenty-three. Everything else becomes “later” by default. This reduces that anxious buzz of “I’m forgetting something” which, fun fact, tenses the shoulders just as much as lifting a heavy box.
Let’s be honest: nobody really does this every single day. Yet every day we don’t, our body quietly absorbs what our brain refuses to sort.
“Whenever a patient told me, ‘I’m exhausted but I can’t switch off my brain,’ I started asking about their back, their jaw, their gut,” says Laura, a general practitioner who specializes in stress-related complaints. “Nine times out of ten, those ‘mysterious’ pains had a story of overload behind them.”
- Check‑in cue: Once a day, ask yourself, “Where does my body hurt right now?” and simply notice without judging.
- Mini-reset: Do three slow breaths plus one gentle stretch (neck, shoulders or lower back) before opening a new “mental tab” like email or social media.
- Soft boundary: Pick a time when your work brain officially closes, even if it’s imperfect, and protect it like you would a doctor’s appointment.
Making space for discomfort to finally speak
There’s a strange moment that happens when people first connect their pain to their pace. They often feel a mix of relief and annoyance. Relief because the pain isn’t “all in their head”. Annoyance because it means change, and change is messy when life is already full.
Yet something shifts the day you stop seeing your body as broken and start seeing it as a messenger. The neck tension before a Zoom call, the heart racing at 11 p.m., the knot in the stomach before checking your bank app. These sensations are data.
They’re crude, clumsy, non-verbal, but they’re messages all the same.
Some will read this and think, “Nice, but my job/kids/life don’t allow me to slow down.” Fair. Reality can be brutal and non-negotiable. What does move, a little, is the way we inhabit it. The micro-pauses between two emails. The choice to drop one commitment that nobody remembers you made.
Over time, those small concessions to yourself add up like compound interest. Less mental clutter, a bit more presence. A jaw that isn’t always clenched. Sunday nights that don’t feel like a countdown to impact.
Your body doesn’t need your life to be perfect. It just needs a few windows where it’s not running on emergency mode.
The tricky part is that mental overload has become so normalized we wear it almost like a status symbol. “Busy” sounds important. “Overbooked” sounds successful. Yet the body is stubborn; it doesn’t care about our social labels. It responds to load.
At some point, the tension, the migraines, the strange fatigue that coffee can’t touch, are no longer random symptoms to fix one by one. They’re a quiet, stubborn invitation to rearrange the way we think, plan, and say yes. Or rather, the way we rarely say no.
Maybe the real question isn’t “What’s wrong with my body?” but “What is my body trying, clumsily, to pull me away from?”

FAQ:
- Question 1How do I know if my pain is from stress or something medical?Start by treating it as both: get checked by a health professional to rule out serious issues, then observe if symptoms fluctuate with your mental load, deadlines or emotional spikes. Patterns over several weeks tell you a lot.
- Question 2Can mental overload really cause chest pain?Yes, stress can trigger muscle tension, rapid breathing and palpitations that feel like chest pain, but chest pain should always be evaluated urgently to exclude heart or lung problems first.
- Question 3My job is intense, I can’t change that. What can I change?You can adjust how you recover: short breathing breaks, realistic to‑do lists, clearer cut‑off times, less screen scrolling at night and small pockets of movement during the day all reduce the total load.
- Question 4Why do symptoms often appear when I finally rest, like on weekends or holidays?When you slow down, your nervous system has the first chance to process what’s been pushed aside; tension, fatigue and emotions surface exactly when there’s finally space for them.
- Question 5Is therapy useful if my problem feels mainly “physical”?Often yes: a good therapist can help you untangle chronic stress patterns, perfectionism and boundaries, which can ease physical symptoms that come from long-term overload.
