ELI5:Why do we enjoy spicy food, when it's supposed to be a deterrant?
gpt
Spicy food creates the sensation of pain.
Pain causes the brain to release endorphins as a natural painkillers
Morphine and other opiates bind with the same parts as our brain that endorphins do, so opiates are like huge doses of fake endorphins.

So natural endorphins cause minor amounts of the same things, namely, dulling pain and euphoria. Endorphins are what causes "runner's high" too.

So basically, endorphins are like natural opium that your brain gives its self when it feels pain to cheer it's self up, so when people eat spicy food, they feel good. The response varies from person to person, which is why some people hate spicy food, and some people are spice crazy.
