ENDORPHINS
Endorphins
Endorphins are endogenous opioid peptides that function as neurotransmitters. They are produced by the pituitary gland and the hypothalamus in vertebrates during exercise, excitement, pain, spicy food consumption, love, and sexual activity, and they resemble the opiates in their abilities to produce analgesia and a feeling of well-being.The above text is a snippet from Wikipedia: Endorphins
