Sensory Processing Disorder: What It Really Feels Like
Imagine walking into a grocery store and being hit all at once by buzzing fluorescent lights, clattering carts, cold air from the freezer aisle, and the smell of a dozen different foods. For most people, the brain quietly filters most of this out. For someone with Sensory Processing Disorder (SPD), none of it gets filtered. It all comes rushing in at full volume, all at once.
SPD is a condition where the brain has trouble receiving and responding to information that comes in through the senses. This isn’t just about sight and sound. It includes touch, taste, smell, balance, and even the sense of where your own body is in space. In a typical brain, sensory input gets sorted, prioritized, and toned down so a person can function smoothly. In a brain affected by SPD, that sorting system doesn’t work the way it should.
There are generally two sides to this. Some people are oversensitive, meaning ordinary sensations feel overwhelming or even painful. A tag on a shirt might feel like sandpaper. A hug might feel like being squeezed too hard. A room full of chatter might feel like standing next to a jet engine. Other people are under sensitive, meaning they don’t register sensations strongly enough. They might not notice they’re hurt, may crave intense movement like spinning or crashing into things, or may not feel full after eating.
It’s important to understand that SPD isn’t about being dramatic or “too sensitive” in a personality sense. It’s a real difference in how the nervous system processes information. Someone with SPD isn’t choosing to be bothered by a scratchy sweater or unable to sit still in a noisy classroom. Their brain is genuinely struggling to manage the flood of input.
SPD often shows up in children, and it’s frequently seen alongside autism, ADHD, and other developmental differences, though it can also occur on its own. A child with SPD might melt down in a loud cafeteria, refuse certain textures of food, or seem clumsy because their sense of balance isn’t giving them accurate signals. Adults can have it too, though it sometimes goes unnoticed for years because they’ve built quiet coping habits, like avoiding crowded places or wearing noise-canceling headphones, without ever having a name for why they needed to.
The good news is that Sensory Processing Disorder (SPD) is manageable. Occupational therapy is one of the most common and effective approaches. Therapists use structured sensory activities to help the brain learn to organize and respond to input in a calmer, more predictable way. Simple everyday tools help too, like weighted blankets, noise-reducing headphones, textured toys, or having a quiet space to retreat to when things feel like too much.
Perhaps the most helpful thing anyone can offer someone with SPD is patience and understanding. What looks like an overreaction from the outside is often a very real, very physical experience on the inside. When we stop asking “why can’t you just deal with it” and start asking “what would make this easier for you,” we create space for people with SPD to feel safe, understood, and capable of thriving in a world that isn’t always built with their senses in mind.
