Tolerance wasn’t something I lost overnight. I noticed it as a narrowing — the quiet realization that environments I once handled easily now asked more of me than they used to.

When things finally got quieter, I expected relief. Instead, my body felt more uncomfortable — not because anything got worse, but because the noise that had been carrying me fell away.

Exposure threshold wasn’t something I crossed all at once. I felt it as a limit — the quiet moment when my body stopped compensating and let me know it had reached enough.

I didn’t become more emotional — I became more permeable. Indoors, feelings reached me faster and lingered longer, like my system had less insulation than it used to.

Repeated exposure didn’t feel dramatic. I noticed it as familiarity — the way the same indoor conditions kept showing up in my body, even when each moment felt manageable on its own.

When I stopped moving, everything felt heavier. Indoors, stillness without exertion made the discomfort clearer — not because my body was weaker, but because nothing was buffering the load anymore.

Prolonged exposure wasn’t about one bad moment. I felt it as duration — the quiet way my body changed the longer I stayed in the same indoor environment.

It wasn’t a spike or a crash — it was a drift. Over time, my nervous system stopped returning all the way to baseline, like balance slowly shifted without a clear moment of change.

Background exposure wasn’t something I noticed directly. I felt it as constancy — the sense that my body was always responding to something small, steady, and never fully absent.

Nothing changed when I was alone — except my body stopped performing. Without distraction or shared attention, what I felt indoors became clearer, not because it intensified, but because there was nothing buffering it.
