What do the elements in something like Wusabi, or Chilly Peppers, or what have you, actually do to create this “hot” sensation we feel in our mouths, noses, throats, and heads? Anatomically speaking, what is affected within us to create such a reaction, and why?

Welcome to the Straight Dope Message Board.

I was going to be a smart ass and tell you to search the archives, but I tried, and unless you knew to look for “capsaicin” it wasn’t that obvious.

It’s covered in a staff report:

[Are birds immune to hot pepper, enabling them to eat vast amounts and spread the seeds?](http://www.straightdope.com/mailbag/mchili.html)

BTW, it’s “Wasabi” and “Chili”…
