dopamine

Endorphins are peptides that act as neurotransmitters, and belong to the endogenous opiod system. The term “endorphin” is a compound of “endogenous” and “morphine”, referring to a chemical that is naturally produced within the body and that demonstrates effects similar to morphine, in terms of producing analgesia and feelings of well-being. Endorphin production can be stimulated through excitement, pain, exercise, love and orgasm, or even eating spicy foods.
