Endorphins and other morphine-like substances known as opioids, which are released during exercise, don't just make you feel good -- they may also protect you from heart attacks, according to University of Iowa researchers.
The UI study investigated the idea that the opioids produced by exercise might have a direct role in cardio-protection. The researchers compared rats that exercised with rats that did not. As expected, exercised rats sustained significantly less heart damage from a heart attack than non-exercised rats. The researchers then showed that blocking opioid receptors completely eliminated these cardio-protective effects in exercising rats, suggesting that opioids are responsible for some of the cardiac benefits of exercise.
This result raises the possibility that some day an opioid/endorphin injection or pill might deliver the benefits to your heart that you currently have to get by hard and time-consuming exercise. Time for your exercise injection.
When you can get all the health benefits of exercising without exercising will you still exercise? (assuming that you exercise now)
