相信很多人都聽過

有些人不開心時會吃辣,即使他本身是不太吃辣的

關於辣椒素與興奮感的關係  最近找了些資料

確實是有科學根據的  (其實知了很久Orz ,不過想不到都是與endorphins有關)

^{Folklore among self-described "pepperheads" attributes this to pain-stimulated release of endorphins, a different mechanism from the local receptor overload that makes capsaicin effective as a topical analgesic.}

^{In support of this theory, there is some evidence that the effect can be
blocked by naloxone and other compounds that compete for receptor sites
with endorphins and opiates.} 

暫時沒有空找mechanism  下次得閒再search  Orz
