When preparing dinner, my friend and I sometimes argue over the amount of pepper. It is often ‘too hot’ for him while I enjoy the heat effects (endorphins) of capsaicin (chili peppers) and piperine (black pepper). Is there a way to experience the endorphins effects of pepper without a burning sensation?
According to my research, the effect of capsaicin that causes the burning sensation is indirectly responsible for the pleasurable release of endorphins, which are the brain's way of counter-acting the pain sensation. If you don't feel any burn, then you probably haven't consumed enough capsaicin to trigger the endorphin rush.
This source from Northwestern University provides the most succinct summary:
Capsaicinoids trick the brain into thinking it is being burned, which is a painful experience, through the transmission of neurotransmitters [...] The brain responds by releasing another type of neurotransmitter known as endorphins. Endorphins are the body’s natural way of relieving pain by blocking the nerve’s ability to transmit pain signals.
