Your Child's Stomach Aches Before Exams Are Real. Here Is What to Do With Them.

I want to start with something that matters: your child is not making it up.

The stomach ache the morning of an exam is real. The headache that arrives during the two weeks before assessments is real. The nausea on Sunday evenings, the early waking before test days, the shakiness that appears in the minutes before the exam begins — all of this is physiologically genuine. The nervous system is doing exactly what it is designed to do. The problem is simply that it is doing it in the wrong context.

This matters enormously because of what happens when we don't believe the symptom. When a parent says "you're just nervous, it's not a real stomach ache" — however gently, however reasonably — the child receives two messages simultaneously. The first message is: your body's signals are unreliable. The second, and more damaging message is: your distress is not the kind that warrants attention. Both of these messages create problems that persist far longer than the exam season.

What is actually happening in the body

The human stress response is ancient and elegant. When the brain perceives threat, the hypothalamus triggers a cascade: adrenaline and cortisol release, heart rate increases, blood flow is redirected from digestion to the large muscles, breathing becomes shallower. This is the fight-or-flight response, and it evolved to help us deal with predators, not examinations.

The digestive redirection is why stomach aches are the most common somatic anxiety symptom in children. When blood flow leaves the digestive system, the gut becomes genuinely uncomfortable. Nausea, cramping, loose bowels, loss of appetite — these are not psychosomatic in the dismissive sense of "just psychological." They are the direct physical consequence of a stress response that is real, even when the threat is a maths paper rather than a lion.

The sleep disruption is a cortisol effect. Cortisol is highest in the early morning, and when anxiety is high, the body anticipates the threat earlier — waking children at 5 AM with the sense that something is wrong even before consciousness has identified what.

Headaches often result from a combination of muscle tension (particularly in the neck and shoulders, which tighten under stress) and changes in breathing patterns. Anxious breathing tends to be shallow and thoracic rather than deep and diaphragmatic, which affects oxygenation and can trigger headache.

Knowing that these symptoms have this mechanism is useful for parents because it shifts the framing. You are not dealing with a behaviour problem or a performance problem. You are dealing with a nervous system that has learned to respond to academic assessment as though it were a physical threat.

What not to do

Several common parental responses to pre-exam somatic symptoms inadvertently make things worse.

Dismissing the symptom ("you're fine, everyone gets nervous") teaches the child to distrust their body signals and to hide distress. Over time, this produces children who present as coping when they are not.

Catastrophising the symptom in the other direction ("I think something is seriously wrong, let me call the doctor") teaches the child that their physical sensations are dangerous and alarming, which amplifies the anxiety response itself.

Allowing exam avoidance as a consequence of the symptom is the most complex issue. If a child genuinely cannot attend school because of physical distress, that needs to be taken seriously. But if patterns emerge where somatic symptoms reliably produce absence from assessment without any other intervention, the child's nervous system learns that distress is the route to escape. This does not mean forcing an overwhelmed child to sit exams. It means not solving the problem only with avoidance.

Techniques that actually help

These are approaches I use and teach in clinical practice. They work when practised regularly, not only when symptoms are acute.

Diaphragmatic breathing. This is the single most accessible physiological intervention. Breathing from the belly — with the hand on the stomach, feeling it rise and fall — activates the parasympathetic nervous system and begins to down-regulate the stress response within a few minutes. For children, I teach this as "belly breathing" and practise it as a game: see how much your belly can expand like a balloon.

The critical thing: practise this when the child is not anxious. Trying to introduce a new breathing technique to a child in the grip of pre-exam panic is very difficult. It needs to be learned in calm, so it can be accessed in crisis.

The 5-4-3-2-1 grounding exercise. Name five things you can see, four things you can hear, three things you can touch, two things you can smell, one thing you can taste. This exercise works by pulling attention into sensory present-moment experience and interrupting the anxious thought loop. Children often enjoy it as a kind of observation game. It takes about two minutes and is highly portable — it can be done on the bus to school.

Temperature. Cold water on the wrists and face triggers a vagal response — the diving reflex — that slows the heart rate and can reduce acute anxiety rapidly. This is particularly useful for the moment before entering the exam room. A cold water bottle, cold water from a tap, even an ice cube held briefly — these are simple, accessible tools.

Movement. The stress response prepares the body for physical action. When action doesn't happen (because we're sitting in an exam hall), the activation has nowhere to go. Brief, vigorous physical activity — a brisk walk, jumping jacks, running on the spot — before a stressful event metabolises some of the adrenaline and reduces the somatic symptom load.

Warm heat on the abdomen. For stomach aches specifically, a warm water bottle or heat pack on the stomach activates the parasympathetic nervous system and can provide genuine physical relief. It also communicates care — which has its own regulatory effect.

A word about your presence

In my practice and in my own experience as a mother, I have come to believe that parental co-regulation is the most powerful calming tool available to young children. Children, particularly younger ones, regulate their nervous systems through contact with regulated adults. Your calm body, your steady voice, your physical presence without visible anxiety — these settle a child's system in ways no technique can replicate.

This is not an accusation if you are anxious yourself. Parental anxiety about children's exams is completely understandable. But if you can practise your own version of the breathing, or use your own grounding techniques, before you sit with your distressed child — you will bring them something no revision schedule can.

You will bring them a nervous system that says: this is manageable, and I am here.

That message, received through the body before it is understood in the mind, is where recovery begins.
