Gut Feeling: What Your Body Knows Before You Do
I'm writing this post shortly after realizing, once again, the incredible wisdom and power our bodies hold. I'm currently in Ecuador, having just completed another Yoga Teacher Training. The original plan was to travel to Egypt right after the training to visit my best friend.
On the morning of my departure to Egypt, nausea set in at 4 a.m. Stomach pain, vomiting, diarrhea—the full package. The taxi was supposed to pick me up at seven. I didn't get in.
Food poisoning, I thought. It happens. Even though I hadn't had a single issue in five months in Ecuador. Even though everyone else at the same table was completely fine the next day. Even though the pizza I shared had zero effect on the other person.
By the afternoon, I felt fine again. So the following day, I set out to rebook the flight. Changing the original ticket wasn't an option—as usual, I had picked the cheapest fare. Getting from Ecuador to Egypt isn't a simple route, but I found a way. A few hours later, an email arrived from the agency: prices had surged so dramatically that they couldn't honor the booking. Canceled.
Ayyy. It felt as if Ecuador wanted to keep me around a little longer. The apartment in Egypt had been booked ages ago, my best friend was waiting, and I was so excited to see her. So I kept searching and booked for a third time.
And then, almost exactly a week later—on the day of this third departure—I was sitting in a closing meeting. It started all over again. The same stomach pain. The same creeping nausea. The same undeniable knowledge that in half an hour, I’d be in the bathroom.
To this day, I don't know if it was food poisoning both times. I can't prove it, and I don't care to. What's far more interesting is something else: what I actually did with that signal the second time around.
THE SCIENCE
What happens in your gut when something feels off
Embedded within the wall of your digestive tract lies its very own nervous system. Estimates range from one hundred to six hundred million nerve cells, distributed along the entire path from the esophagus to the rectum. Technically, it is known as the enteric nervous system. It regulates digestion largely independently, even without orders from above.
"Second brain" is the common metaphor for it. It is both helpful and misleading: this network does not think—it has no thoughts and no intentions. But it perceives. And it signals.
Above all, it signals primarily in one direction. The vagus nerve connects the abdomen and the brain, and roughly eighty percent of its fibers run from the bottom up, from the body to the head. Only about twenty percent carry instructions in the opposite direction. Your body talks significantly more than it listens. I’ve described in detail how this pathway works and how you can strengthen it in my article on the vagus nerve.
These signals almost never reach your conscious mind as raw information. You don't receive raw data about intestinal movement or muscle tension. You get a feeling: tightness, heaviness, a flutter, a tug. That's why it doesn't feel like knowledge. It feels like a mood.
The fact that stress plays a role here is well documented. Persistent stress has been proven to alter gut motility and pain sensitivity in the abdominal region.
THE CAVEAT
Why your gut feeling isn't always right
Neuroscientist Antonio Damasio calls these signals somatic markers: past experiences leave physical traces that signal before you’ve had a chance to consciously weigh your options. While influential, this hypothesis is not without controversy. Subsequent research showed that test subjects possessed far more conscious awareness than previously assumed. The body doesn't act as a sole decision-maker as much as the popular narrative suggests.
A study by Dunn and colleagues (2010) is even more revealing. People who were more accurate at perceiving their own heartbeat showed a tighter coupling between physical reaction and felt arousal. Expected enough. But the second part is surprising: better bodily awareness didn't automatically lead to better decisions. It helped or harmed depending on whether the signal pointed in a favorable or unfavorable direction.
Even when your gut feeling gives you instructions, be aware that it draws on past experiences. And experiences can also carry old fear and avoidance. Those who feel more finely can also tune into old patterns more intensely—just as easily as they tune into wise impulses. I’m someone who often follows my gut, yet I still want to leave you with this: don't trust your gut blindly. First, learn to truly feel it, and then learn to discern.
ANCIENT KNOWLEDGE
What traditions knew about the gut
Long before anyone could count nerve fibers, various traditions attributed a distinct agency to the abdominal region. And strikingly consistently, they viewed it not just as a corner for emotions, but as a foundation. That proves nothing. But it is worth taking a closer look.
In Hawaiian Huna, this part is called Unihipili: the unconscious, emotional self, symbolically located in the abdomen and understood as the guardian of the body, memory, and life energy. What's interesting is the role attributed to it there. In this concept, the conscious head-self, ʻUhane, cannot connect directly with the higher self. Every intention, every prayer first goes down to the Unihipili, and only when it establishes trust does it release the energy to carry the intention forward. So the belly is not the destination, but the eye of the needle.
And according to this teaching, it behaves like a very sensitive child. It needs attention and safety. If it is continuously bypassed, criticized, or ignored, it reacts with defiance, fear, or physical symptoms. Iris, the elder who told me about this, put it dryly: "The first time, maybe it was the food. The second time, not anymore."
In Zen, Hara is the center in the lower abdomen, a few fingers' breadth below the navel. Karlfried Graf Dürckheim, who brought the concept to Europe, described it as the center from which a person acts when they are not acting out of tension. In Japanese disciplines like archery, calligraphy, and martial arts, technique isn't trained first; instead, the focus is on this downward shift. Whoever acts from the head tenses up. Whoever acts from the Hara is centered. Here too, the belly is not just a place of feeling, but the place from which things happen.
In Yoga, this is where Manipura lies, literally the "city of jewels," connected to Agni, the inner fire. In this philosophy, the same force that digests food also digests experiences. If it is weak, both just sit there. The food and the experience. Manipura therefore stands for willpower and agency: for the ability to actually do something rather than just knowing it.
Three traditions, three languages, the same observation: The gut is not merely a digestive organ, nor is it merely a feeling. It is the place where something is allowed through. Or not.
THE THREE CENTERS
How to make sense of your gut feeling instead of being at its mercy
In my work, I approach signals like these through three centers. Not because it sounds nice, but because a gut feeling needs something different at every level.
Head · Understanding
Knowing that eighty percent of vagus nerve fibers report upward takes away the eeriness of the feeling. It’s neither imagination nor superstition—it's a channel that is constantly running anyway. Understanding creates safety.
Heart · Feeling
Perceiving a signal means letting it be for a moment without immediately explaining, judging, or rationalizing it away. That is precisely the step most people skip. Feeling creates peace.
Gut · Embodying
And then comes the real work: discerning whether that tightness is a warning or just a habit. That can't be done in your head. It only happens by staying in your body and observing what unfolds. Sensing creates clarity.
SOMETHING TO TRY
Two Paths on the Floor
We mull over most decisions sitting down. In doing so, the body stays completely still—and along with it, whatever it might have to say. This exercise shifts the question directly into the room. You’ll need ten minutes, a bit of space, and two sheets of paper.
Set up. Write one of your choices on each sheet of paper. Keep it brief—three or four words are plenty. Place the sheets on the floor a few steps apart so that a short path leads to each. Find a starting point in the middle.
Arrive at neutral. Stand at your starting point, barefoot if possible. Feel the ground beneath both feet. Take a few breaths with a lengthened exhale until your body settles. If that feels difficult, start with a quick stress-relief breathing technique first, such as extended exhales. Don’t think yet—just stand.
Walk the first path. Walk slowly toward the first sheet. Notice how walking feels along the way: do your steps feel lighter or heavier? Stand on the sheet and look in the direction this path would take you. Stay there for a moment. What’s happening in your belly, chest, and jaw? How is your pelvis aligned? Where is your breath moving? Don't judge anything; simply describe it to yourself.
Return to center, then walk the second path. Step back, shake out your arms and legs, and wait until you return to neutral. This step is crucial—otherwise, you’ll carry the residue of the first path into the second. Then repeat the process with the other sheet: walk over, stand, and tune in.
Discern. Return to the center. Now for the pivotal question: Which path was easier to walk, and was that true lightness or avoidance? Does the tightness you felt on one sheet feel like withdrawal or excitement? Both can feel similar, yet mean opposite things. If you can't tell them apart today, don't make a decision yet. This exercise provides you with data, not an instant answer.
TANGIBLE SHIFTS
What changes when you start listening
You won't magically make the "right" choice every single time. What actually shifts is something deeper.
You start catching signals earlier—before your body is forced to get loud. You create space between impulse and reaction, instead of wondering afterward why you said yes yet again. And you begin to recognize your own patterns: Which tightness keeps returning, and what is it actually warning you about?
I canceled a trip to Egypt. The apartment was booked, my best friend knew, and I had been so excited. It wasn't an easy decision, but I know it was the right one.
I was proud of myself because I stopped doing things just because "that's what you're supposed to do." Because it's normal. Because that's how it's done. Once again, I listened—and that alone was the entire point.
