How does exercise help relieve menstrual discomfort in adolescents?

• A. Releasing endogenous opiates
• B. Increasing prostaglandin production
• C. Decreasing vasodilation
• D. Reducing pelvic discomfort

Answer: (A)

Regular exercise relieves menstrual cramps primarily by triggering the release of endorphins, the body's natural opioids. These endorphins bind to receptors in the brain and spinal cord to dampen pain signals and raise the threshold for pain, making cramps feel less intense. In adolescents with cramps caused by prostaglandin-driven uterine contractions, this analgesic effect helps reduce the perceived pain. Exercise doesn’t increase prostaglandin production; if anything, the pain relief comes from the endorphin surge and the associated mood benefits, which can further lessen how distressing the cramps feel. So, the key mechanism is endorphin-mediated analgesia that lowers pain perception, rather than changes in prostaglandins or vasodilation.
