The Sensitive Patient
Why Am I So Sensitive?
We are built to sense the world around us.
The problem is not sensitivity itself. The problem arises when the threshold for responding becomes too low, the response becomes too large, or the system has difficulty returning to baseline.
We need to notice pain, temperature, hunger, movement, sound, light, danger and changes inside our own bodies. Sensitivity is not a flaw — it is part of how we protect ourselves, adapt and respond to our environment.
But when we feel too much, too often, and without enough respite, that same protective system can become overwhelming and exhausting.
A sound feels too loud. A smell feels intolerable. A normal meal causes disproportionate symptoms. Exercise takes days to recover from. A medication that most people tolerate causes an outsized reaction. Even ordinary stress can feel as though it pushes the body past its limit.
This is where the idea of a sensitive system becomes useful.
In a sensitive system, an ordinary signal may not be adequately filtered or dampened, the threshold for responding to it may be lower, or the response itself may become amplified. The result is that relatively small inputs can produce disproportionately large responses.
And once the system has responded, it may have difficulty switching that response off and returning to baseline.
Sensitivity, then, may not simply be about feeling more. It may also be about having greater difficulty filtering, regulating and recovering from what we feel.
That Joke Isn’t Funny Anymore
Heightened sensitivity is not a diagnosis on its own.
It can appear as part of many different health conditions, and the underlying biology may not be the same from one person to another. What these conditions can sometimes share is a similar pattern:
The response is larger, lasts longer, or requires more recovery than we would expect from the size of the original stimulus.
Most of us have experienced a milder version of this in everyday life.
Imagine you have been stressed at work, sleeping poorly, eating badly, and perhaps had a few too many drinks the night before. One of your children is having a difficult morning, your partner is sick, the house is noisy, and you're already running late.
Something relatively small can suddenly feel enormous.
The spilled cereal. The traffic jam. The extra question. The noise in the background.
Any one of them might be enough to push you over the edge.
Now imagine those same stressors after several nights of good sleep, regular meals, exercise, time outside and a relaxing weekend.
The stressors have not changed.
Your capacity to handle them has.
We see the same thing in children.
A child who is well rested, fed, physically active and comfortable may tolerate frustration remarkably well. The same child who is hungry, overtired, overstimulated and hasn't had enough opportunity to move can completely unravel over something that would normally barely bother them.
And for some women, the same principle can be noticeable across the menstrual cycle.
A joke, inconvenience or comment that barely registers at one point in the month may feel much more irritating or overwhelming in the premenstrual phase.
The joke did not change.
That joke isn't funny anymore.
The physiological context in which it was received has changed.
This is an important idea because the body does not respond to a stimulus in isolation.
It responds based on the state of the system when that stimulus arrives.
The trigger may be small.
