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 |
