Where Anxiety Shows Up in the Body

You've probably heard the phrase "it's all in your head" about anxiety. It's not. Anxiety is a full-body experience, and for a lot of people (and a lot of kids), the body sends the message long before the mind catches up to what's actually going on.

If you've ever had a racing heart before a presentation you didn’t know you were nervous about, or watched your child clutch their stomach on a school morning with no obvious trigger, you've seen this in action. Let's talk about why that happens and where to actually look for it.

Why Anxiety Lives in the Body, Not Just the Mind

Your nervous system is built to protect you from danger, and it doesn't wait around for your rational brain to weigh in first. When it senses a threat, real or perceived, it triggers a fight, flight, or freeze response: heart rate climbs, muscles tense, breathing gets shallow, digestion slows down. This system doesn't know the difference between an actual emergency and a stressful email, a tough conversation, or a pop quiz. It reacts the same way either way.

This can often feel confusing. The physical response feels so much bigger, random, because the "danger" isn't a tiger. It's a meeting, a deadline, a fight with a friend, a test. But the body doesn't get that memo. It just responds.

A Head-to-Toe Look at Where This Shows Up

Head and mind. Racing or repetitive thoughts, trouble concentrating, difficulty making even small decisions, tension headaches.

Chest and heart. A tight or heavy feeling in the chest, a racing or pounding heart, shallow or quick breathing that can sometimes feel like you can't get a full breath in.

Stomach. Nausea, "butterflies," a knotted or upset stomach, appetite changes in either direction (not hungry at all, or reaching for food to self-soothe).

Muscles. Jaw clenching, shoulder or neck tension, restlessness, an inability to sit still, or the opposite: feeling physically frozen.

Sleep. Trouble falling asleep because the mind won't quiet down, or waking up already feeling wired and on edge before the day has even started.

None of these symptoms are exclusive to anxiety, which is part of why they're so often missed or misattributed. But when several of them show up together, especially in a repeating pattern tied to a specific situation, that's usually the nervous system trying to tell you something.

How This Looks Different for Kids

Kids usually don't have the language yet to say "I'm anxious." What they have instead is a body that reacts, and a limited vocabulary to explain it. So it comes out as "my stomach hurts," a sudden headache, tears that seem to come out of nowhere, or an outburst that is not matching whatever just happened. A good indicator that these could be symptoms of anxiety are when the pattern persists, particularly around school mornings, new events, or changes. 

How This Looks Different for Adults

Adults are often better at naming the feeling, but many have also spent years normalizing it. Chronic low-grade anxiety can start to feel like "just how I am," a jaw that's always a little tight, a stomach that's never quite settled, sleep that's never quite restful. It gets absorbed into personality ("I'm just a worry-wart," "I'm a little high strung") instead of recognized as something the nervous system is actively doing, and something that can actually shift with the right support.

What to Do With This Awareness

1. Name the sensation without judgment. "My chest is tight" or "my stomach is in knots" is more useful than "I'm fine," even if you don't yet know the reason behind it.

2. Try slowing the breath down. A longer exhale than inhale (in for 4, out for 5) signals safety to the nervous system faster than most people expect.

3. Know when to loop in a doctor first. Physical symptoms deserve medical attention, especially if they're new, severe, or unexplained. Ruling out other causes isn't a detour from addressing anxiety; it's part of doing it responsibly.

4. Bring the pattern to therapy, not just the moment. A single stressful day isn't usually the concern. A repeating pattern, tied to certain situations or times, is worth exploring with support.

If This Sounds Familiar

Whether it's your child's stomachaches every school morning or your own jaw that never quite unclenches, these patterns are worth paying attention to, and they're very treatable. I work with both kids navigating school anxiety and adults working through anxious thought patterns, all through online sessions that fit into a real schedule.

My Child Says Their Stomach Hurts Every School Morning — Is It Anxiety?

If you're reading this at 7:15am with a kid on the couch clutching their stomach and refusing to put their shoes on, first: breathe in, breathe out. You're not imagining the pattern and you're not a bad parent for feeling exhausted by it.

Here's the thing about kids and anxiety: it rarely shows up looking like anxiety. It shows up looking like a stomachache. A headache. Sudden nausea that seems to vanish by 10am, or on weekends, or the second summer break starts. Parents often go through the pediatrician route first (which is exactly the right move, ruling things out physically always comes first) and then land in my office asking some version of, "Is this actually anxiety? And if it is, why does it feel so real to them?"

So let's talk about that.

Are the school tardies and absences adding up already? Let’s talk about what could really be going on.

Why Anxiety Shows Up in the Body First

Kids don't usually have the language yet to say "I'm anxious about the math test" or "I'm worried I won't have anyone to sit with at lunch." What they do have is a nervous system that reacts to stress the same way an adult's does. Think racing heart, tight chest, upset stomach. The body prepares for fight or flight. Except they don't yet have the vocabulary to connect the feeling to the cause. So instead, the body just... talks. Loudly. Usually right around 6:45am on a school day.

This isn't manipulation. It isn't your child "faking it" to get out of school. The stomachache is real, the nervous system doesn't know the difference between "I'm scared of the pop quiz" and "there's a tiger in the room." It reacts the same way either way.

A Few Questions That Can Help You Tell What's Going On

• Does the stomachache show up mostly on school mornings, and ease up once they're actually settled at school, or by afternoon?

• Does it disappear almost completely on weekends or during breaks?

• Is there a specific part of the school day they seem to dread — recess, a certain class, lunch, the bus?

• Has anything changed recently like a new teacher, a friendship shift, a bigger transition like a new grade or new school?

None of these questions diagnose anything on their own. But a pattern like "fine on Saturday, miserable by Sunday night, stomach hurts every weekday morning" is a pretty strong signal that something at school, big or small, is weighing on them more than they can put into words yet.

What Actually Helps (Beyond "Just Push Through It")

The instincts to either force them out the door or let them stay home both come from a loving place, but neither one, on its own, actually helps a kid build the skills to move through the anxiety. A few things that tend to make a real difference:

1. Naming the feeling without judgment. Something as simple as, "Your body's telling you it's worried about something, let's figure out what," takes the shame out of it.

2. Small, specific problem-solving. Not "school is scary" in the abstract, but "the walk into the building after the bell feels scary". When we can find the specific trigger, that's something we can actually work on together.

3. Consistency over avoidance. Every day a child stays home to avoid the anxious feeling, the anxiety gets a little more confirmation that school really is something to fear. Gentle, supported exposure, even just getting to the building, matters more than people expect.

4. Getting support before it snowballs. School anxiety that goes unaddressed for a semester looks very different from school anxiety caught in its first few weeks. Look for support from your child’s school. A preferred staff member, the school counselor, or a loyal friend can make a huge difference. 

If This Sounds Familiar

You don't have to figure this out alone, and you don't have to wait until it's a full-blown crisis to ask for help. I work with kids and families navigating exactly this: school anxiety, school refusal, the stomachaches, headaches and meltdowns that come with it, all through online sessions that fit into your actual schedule, not just the once-a-week-if-you're-lucky in-person slot.
