Endorphins

Endorphins are both hormones and neurotransmitters and they can pack a punch. We have at least 20 different types of endorphins some of which are more powerful than morphine. We tend to release endorphins when we’re under stress or in pain. The higher the level of endorphin, the less pain we feel and the more relaxed, even euphoric, we can become. Foods like chocolate or chilli peppers enhance the secretion of endorphins.
