Dynorphin and Endorphins

Dynorphin plays a crucial role in managing discomfort during physical exertion by cooling the body and triggering a feedback loop that enhances sensitivity to endorphins. When faced with discomfort, the body responds by increasing mu-opioid receptors, leading to heightened feelings of pleasure from everyday joys. Recent research explores the use of infrared saunas to elevate core body temperature, mimicking a fever to potentially amplify these beneficial responses.
