Why does extremely spicy food make me feel euphoric?
gpt
It triggers your pain receptors which causes increased endorphines (naturally occurring opioid painkillers) to combat the pain but which also results in euphoria.

Normally you don't really notice as you are also actually hurt, but because the capsaicin just tricks your nerves into think they are burning you can enjoy the effects more.  Similar to a weightlifter's or runner's high.
