The buzz of a fluorescent light
used to drive me out of the room.
I was nine or ten. The fluorescent light in our kitchen made a humming sound that nobody else seemed to hear. My mother said I was making it up. My father did not understand why I refused to eat in that room. I could not explain it. The sound hurt. Not in my ears. Everywhere.
Twenty years later, I know it was not invention. It was sensory hypersensitivity. My brain picks up more information than average and, more importantly, it does not filter. What reaches other people as background noise, I receive at full volume.
What is hypersensitivity?
Hypersensitivity is not a medical diagnosis. It is a trait, a way of functioning. Elaine Aron, the American psychologist who has done the most work on it, calls it the "Highly Sensitive Person" (HSP). Around 15 to 20 percent of the population is thought to have it.
It shows up on several levels. Sensory: sounds, lights, textures, smells arrive at an intensity other people do not perceive. Emotional: you feel other people's emotions as if they were your own. A sad film does not just make you sad, it wrecks you. Cognitive: you process more information at once, which can be a strength but also a source of exhaustion.
Hypersensitivity is not a weakness. But in a world designed for brains that filter normally, it can quickly become draining.
How does it overlap with ADHD and giftedness?
A lot of people with ADHD are also hypersensitive. A lot of gifted people too. And when you have two of these, or all three, it creates a particular mix that nobody explains to you.
ADHD makes sensory filtering even harder. Your brain is already in permanent attentional overload. If on top of that every stimulus arrives at full volume, saturation comes fast. That is why many people with ADHD and hypersensitivity need to withdraw regularly. Not because they are antisocial. Because it is survival.
Giftedness adds a layer of deep processing. You do not just receive the stimulus more intensely. You also analyse it in more detail. A strange look from someone on the street, a neurotypical person forgets it in two seconds. You spend twenty minutes wondering what it meant.
The problem is that these three things mask each other during diagnosis. Giftedness compensates for ADHD, ADHD makes hypersensitivity look like emotional impulsivity, and hypersensitivity makes ADHD look like anxiety. A lot of people get diagnosed with anxiety or depression when the real issue is neurological.
How do you live with it daily?
I am not going to write a list of "10 tips for managing your hypersensitivity." That does not exist. What exists is a gradual learning of your own limits.
Environment. I have learned to shape my space. Noise-cancelling headphones. No fluorescent lights at home, only warm lamps. Clothes in fabrics I can tolerate (polyester is over for me). It sounds ridiculous written down. For me, it changed my daily life.
Recovery time. After a socially intense day or a noisy open-plan office, I need silence. Not ten minutes. Sometimes hours. I have stopped feeling guilty about it. My brain needs to discharge what it absorbed.
Leaving early. I often leave parties before other people. I turn down invitations when I know I am already saturated. I used to push through. I would end up exhausted, irritable, sometimes in tears for no apparent reason. Now I choose.
The body. Hypersensitivity is not just mental. It is physical. Fatigue arrives faster. Headaches too. Sleep is often disrupted because the brain takes time to wind down. It took me a long time to connect my "energy crashes" with sensory overload.
What should the people around you know?
If you are reading this because someone in your life is hypersensitive, here is what I wish my own people had known.
It is not being fussy. When I say the noise bothers me, it is not that I am difficult. It is that my brain receives that information at a volume you do not perceive. Telling me "it is not that loud" does not help. It is the equivalent of telling someone in pain "it does not hurt that much."
The intense emotional reactions are not drama. When I react strongly to something that seems minor to you, it is not for attention. The emotion arrives without a filter. I cannot "just calm down." My brain needs time to process.
The need for solitude is not rejection. When I withdraw after time together, it is not that you bored me or that something is wrong. It is that my brain is full. It needs emptiness to function again.
The best support is not questioning what the person feels. You do not need to understand how it works. Just accept that it is real.
