The eight senses (not five)

You probably learned “five senses” at school. There are really eight:

  1. Sight — light and colour
  2. Sound — auditory input
  3. Smell
  4. Taste
  5. Touch — pressure, temperature, pain, texture
  6. Proprioception — where your body is in space
  7. Vestibular — balance and movement (inner ear)
  8. Interoception — signals from inside your body (hunger, thirst, needing the toilet, heartbeat, emotions)

The last three are usually invisible to people who don't have trouble with them — which is why they're often overlooked in conversations about sensory differences. They matter a lot.

Over-responsive vs. under-responsive

Each sense can be either “too loud” (hyper-responsive) or “too quiet” (hypo-responsive), and a single person can be both in different channels. You can be over-responsive to sound and under-responsive to pain, at the same time.

Over-responsive: certain sounds hurt. Fluorescent lights feel aggressive. Clothing tags are unbearable. Perfume gives you a headache. A light touch on the shoulder can feel like a shove.

Under-responsive: you don't notice you're cold. You don't realise you're hungry until you're hangry. You crave deep pressure (weighted blankets, tight hugs) or loud music or strong flavours — because that's the level of input you need to feel properly regulated.

How it actually feels

  • Walking into a supermarket and feeling like someone turned the world up to 11.
  • Not realising you've been uncomfortable for two hours until you leave the room.
  • Finding out at 30 that “clothes should be comfortable” was always the rule — you just assumed you were the defective one.
  • Being told you're “too picky” about food, fabric, or noise when you're actually just honest about the pain.
  • Needing to rock, fidget, pace, chew, or press on things to think clearly.
  • Meltdowns or shutdowns when input has been too high for too long — not a tantrum, a nervous system overflow.

What actually helps

  • Noise-cancelling headphones or earplugs. Loop, Flare, cheap foam — doesn't matter, just have some.
  • Sunglasses indoors if you need them. No one is judging you.
  • Soft, tagless, predictable clothing. It's okay to wear the same thing every day.
  • Weighted blankets. Deep pressure is genuinely calming for many nervous systems.
  • Stim toys and fidgets. Regulation, not distraction.
  • Interoception cues. Alarms that remind you to drink water, eat, stretch. Outsourcing the signals your body isn't sending clearly.
  • Leaving early. Knowing your exit in advance takes the load off.

Sensory sensitivity isn't being dramatic. It's having a working smoke detector.
